1900
1900 (MCM) was a common year starting on Monday in the Gregorian calendar, serving as the final year of the 19th century and the inception of widespread anticipation for the new millennium, though mathematically the 20th century began in 1901.[1] It featured intensified imperial conflicts, such as the Boxer Rebellion in China, where the Yihetuan movement targeted foreign influences, leading to the siege of international legations in Peking from June to August, ultimately relieved by an allied expeditionary force comprising troops from eight nations.[2] Concurrently, the Second Boer War raged in South Africa, with British forces suffering setbacks like the Battle of Spion Kop in January, highlighting the guerrilla tactics of Boer commandos against a larger imperial army.[1] Natural disasters underscored human vulnerability, notably the Galveston Hurricane on September 8, which devastated Galveston, Texas (population around 37,000)[3], killing 6,000 to 8,000 people with winds exceeding 130 mph and a 15-foot storm surge, prompting innovations in urban flood control.[2] Scientific and technological milestones defined progress amid strife: Max Planck proposed the quantum hypothesis in December to resolve discrepancies in black-body radiation, laying foundational principles for quantum mechanics by positing energy emission in discrete quanta rather than continuous waves.[4] Ferdinand von Zeppelin achieved the first controlled flight of a rigid airship on July 2 over Lake Constance, advancing aerial navigation capabilities.[5] The Exposition Universelle in Paris drew over 50 million visitors, exhibiting electrical innovations, the Eiffel Tower's continued prominence, and early cinematic displays, while the concurrent Olympic Games introduced events like the marathon, emphasizing international athletic competition.[1] Politically, the United States saw Republican incumbent William McKinley secure reelection in November against Democrat William Jennings Bryan, affirming the Gold Standard Act's earlier passage stabilizing currency on gold reserves.[6] In Europe, the Labour Party was founded in Britain via a conference in February, marking organized working-class political representation.[1] These events collectively reflected a world transitioning from 19th-century certainties toward industrialization's uncertainties, with empires straining under internal and external pressures.[2]Overview
Geopolitical and Military Landscape
In 1900, imperial competition among European powers and emerging nations like the United States and Japan intensified efforts to secure trade routes and resources, particularly in Asia and Africa, where foreign legations and economic concessions faced direct threats from local resistance. The Boxer Rebellion exemplified this dynamic, as the Yihetuan (Boxers), a Chinese secret society backed initially by Qing authorities, launched violent attacks on foreign missionaries, diplomats, and converts, culminating in the siege of Beijing's diplomatic quarter from June to August.[7] [8] This anti-foreign uprising, fueled by resentment over unequal treaties and missionary influence, prompted the formation of the Eight-Nation Alliance—comprising Britain, the United States, Germany, France, Russia, Japan, Italy, and Austria-Hungary—which deployed approximately 20,000 troops to relieve the siege on August 14, breaking Boxer and Qing resistance in the capital.[7] [9] The intervention protected vital consular and trade interests, reflecting causal imperatives of defending extraterritorial rights and access to Chinese markets amid rival spheres of influence.[8] The Second Boer War further highlighted Britain's imperial strains in securing African mineral wealth and strategic positions against independent settler republics. By early 1900, Britain had committed over 180,000 troops—the largest expeditionary force in its history—to counter Boer commandos from the South African Republic (Transvaal) and Orange Free State, capturing key cities like Bloemfontein in May and Pretoria in June to consolidate control over gold and diamond regions essential for industrial trade.[10] Despite conventional victories, the Boers adapted to guerrilla tactics, prolonging the conflict and exposing vulnerabilities in imperial overextension against determined local forces defending autonomy.[10] Concurrently, European colonial administrations in Africa and Asia, largely finalized by the 1900 partition, emphasized territorial consolidation to stabilize supply chains; Britain dominated South Africa and India, France controlled much of West Africa and Indochina, while Germany and others held peripheral holdings, all prioritizing resource extraction and market access over local governance.[11] American geopolitical maneuvering underscored shifting Pacific power balances, with the Hawaiian Organic Act of April 30, 1900—effective June 14—formally establishing Hawaii as a U.S. territory, codifying annexation from 1898 to bolster naval bases amid rivalries with Japan and European fleets for transpacific dominance.[12] This expansion secured coaling stations and trade lanes, countering imperial encirclement. Diplomatic initiatives, such as the 1899 Hague Conventions carrying into 1900, attempted to codify warfare rules—including prohibitions on certain weapons and protections for civilians—but lacked enforcement mechanisms, as evidenced by ongoing brutalities in colonial conflicts, revealing the primacy of national interests over nascent international norms.[13]Scientific and Technological Advances
In physics, Max Planck derived a formula for black-body radiation that incorporated discrete energy quanta, resolving inconsistencies between classical electromagnetic theory and experimental spectra observed by researchers such as Otto Lummer and Ferdinand Kurlbaum.[14] He presented this quantum hypothesis on December 14, 1900, to the German Physical Society in Berlin, marking the inception of quantum theory through empirical fitting rather than initial physical interpretation of quanta as particles.[15] Planck's approach started from combinatorial entropy considerations for oscillators in thermal equilibrium, yielding the distribution now known as Planck's law, which accurately matched ultraviolet catastrophe predictions avoided by introducing E = h\nu.[16] In medicine, Karl Landsteiner conducted serological experiments in 1900 at the University of Vienna, identifying three major human blood groups—A, B, and C (later O)—based on agglutination patterns between red blood cells and sera from different donors.[17] These findings, published in early 1901, demonstrated that incompatible mixing caused clumping due to isoagglutinins, laying the groundwork for type-specific transfusions by revealing compatibility as an observable biochemical property rather than universal interchangeability assumed in prior practices.[18] Landsteiner's systematic mixing of cells and sera from staff and patients provided direct evidence against earlier failures in transfusion medicine, where reactions were often fatal without recognition of group disparities.[19] In engineering, Ferdinand von Zeppelin launched the LZ 1, the first rigid airship, on July 2, 1900, from a floating hangar on Lake Constance near Friedrichshafen, Germany, achieving an 18-minute flight at altitudes up to 410 meters despite structural issues like engine failures and girder buckling.[20] The design featured a lightweight aluminum frame enclosing 17 gas cells for hydrogen buoyancy, with external gondolas for 16-horsepower Daimler engines, enabling controlled aerial navigation through empirical adjustments over non-rigid predecessors.[21] This test validated Zeppelin's modular, semi-monocoque structure for scalability, though initial flights highlighted needs for reinforced rigging and reliable propulsion, informing subsequent iterations.[22] Danish dermatologist Carl Rasch described polymorphous light eruption in 1900, linking polymorphic skin lesions—such as eczematous or papular rashes—to ultraviolet exposure in photosensitive individuals via clinical observations of summer recurrences.[23] His terminology emphasized the variable morphology triggered by sunlight, distinguishing it from other photodermatoses through repeated patient histories and exclusion of infectious causes, establishing a basis for recognizing idiopathic photosensitivity in dermatology.[24]Economic Progress and Policies
The Gold Standard Act, signed into law by President William McKinley on March 14, 1900, formally established gold as the sole monetary standard for the United States, defining the dollar as equivalent to 25.8 grains of 90% pure gold, or approximately $20.67 per troy ounce.[25] This legislation ended the lingering bimetallism debate following the 1896 election and de facto specie resumption in 1879, anchoring the currency to a tangible commodity and thereby limiting discretionary monetary expansion.[25] Empirical evidence from the era indicates that this fixed framework contributed to monetary stability, with reduced long-term inflation volatility compared to periods of fiat experimentation, fostering confidence in U.S. dollar-denominated trade and credit markets.[26] By tying paper money redeemability exclusively to gold reserves, the Act supported international commerce, as foreign holders could reliably convert dollars without fear of debasement, aligning with classical economic principles that prioritize sound money for sustained growth.[27] The U.S. population reached 76,212,168 according to the 1900 census, reflecting robust natural increase and immigration inflows that expanded the labor pool for industrialization.[28] Between 1890 and 1900, over 3.7 million immigrants arrived, primarily from Europe, providing low-cost labor that correlated with surges in key sectors: steel production doubled to around 10 million tons annually by 1900, oil output exceeded 63 million barrels, and railroad mileage grew to over 193,000 miles, facilitating resource extraction and market integration.[29] These developments, driven by entrepreneurial capital accumulation and minimal regulatory interference, positioned the U.S. to command half of global manufacturing capacity by century's end, with immigration-fueled workforce expansion enabling efficient division of labor and technological adoption in assembly-line precursors.[29] Such dynamics exemplified how open labor markets and property rights incentivized productivity gains, outpacing agrarian constraints. The Foraker Act, enacted on April 2, 1900, reorganized Puerto Rico's governance post-Spanish-American War, imposing a civilian administration while subjecting island imports to the U.S. to a 15% ad valorem duty under the Dingley Tariff schedule, though allowing duty-free U.S. exports to Puerto Rico.[30] This framework integrated Puerto Rico's economy into U.S. orbits by exempting the territory from federal income taxes and providing preferential market access, which spurred export growth in sugar and tobacco—Puerto Rican sugar shipments to the mainland rose from 200,000 tons in 1901 to over 300,000 by 1904—as colonial producers adapted to American demand and infrastructure investments.[31] Despite initial tariff frictions, the Act's structure promoted trade liberalization relative to prior Spanish mercantilism, enabling capital inflows and agricultural specialization that boosted per capita output, though full tariff reciprocity awaited the 1917 Jones-Shafroth Act.[32] Globally, commodity trade expanded amid colonial resource mobilization, with raw cotton exports from U.S. and British India totaling over 10 million bales annually by 1900, underpinning textile industrialization through efficient plantation scaling and rail transport.[33] Rubber production similarly surged from 10,000 tons in 1875 to over 50,000 tons by 1900, fueled by wild extraction in the Belgian Congo and Dutch East Indies, where colonial enforcement lowered costs and met rising pneumatic tire demand from automobiles and bicycles.[34] These flows, facilitated by imperial efficiencies in labor coercion and extraction technology, enhanced supply chain reliability for industrial powers, correlating with falling real prices—rubber dropped 20% in the 1890s—and broader prosperity via comparative advantage, unencumbered by protectionist distortions.[35]Cultural and Social Dynamics
In 1900, Sigmund Freud published The Interpretation of Dreams, a work derived from clinical case studies that proposed dreams as pathways to the unconscious mind, establishing core tenets of psychoanalysis.[36] This text, completed in 1897 but released publicly in 1900, emphasized wish-fulfillment in dream content and introduced methods for symbolic interpretation, influencing subsequent psychological inquiry despite methodological debates over empirical verifiability.[37] Societal shifts toward urbanization accelerated, driven by mechanized agriculture displacing rural labor toward factory employment in expanding industrial centers. In the United States, the 1900 census recorded approximately 40% of the population residing in urban areas, a marked increase from prior decades, correlating with agricultural productivity gains that released workers for urban manufacturing roles.[38] This migration pattern reflected broader global trends, where improved farm machinery reduced agrarian labor needs, fostering denser city populations and altered daily social structures around wage work and communal living. The Exposition Universelle in Paris, attended by over 50 million visitors from April to November, served as a nexus for cultural exchange, exhibiting Art Nouveau designs, colonial artifacts, and early cinematic projections that integrated moving images with sound in short films.[39] Coinciding with the second modern Olympic Games (May to October), which drew 997 athletes from 24 nations across 95 events including the first Olympic marathon, these events highlighted emerging internationalism in sports and leisure, with American competitors dominating track-and-field while French participants amassed the highest medal tally.[40] Fashion trends, exemplified by the Gibson Girl ideal of tailored blouses, corseted waists, and high collars for women alongside men's sack suits, mirrored this era's blend of formality and nascent mobility, as bicycles and early automobiles encouraged practical yet elegant attire suited to modern paces of life.[41]Chronological Events
January
Chiune Sugihara, a Japanese diplomat who later saved thousands of Jewish lives by issuing transit visas during World War II, was born on January 1, 1900, in Yaotsu, Gifu Prefecture, Japan.[42][43]Xavier Cugat, a Spanish-born musician and bandleader known for popularizing Latin music in the United States, was born on January 1, 1900, in Girona, Catalonia, Spain.[44][45]
Edith Frank (née Holländer), mother of diarist Anne Frank, was born on January 16, 1900, in Aachen, Germany.[46][47]
February
In February 1900, adherents of the Yihetuan movement, known as Boxers, intensified assaults on foreign-associated infrastructure in northern China, targeting segments of the German-built Tianjin-Pukou railway and Russian-influenced lines in Manchuria, which empirically halted rail traffic and severed supply chains for over 100 miles in affected areas.[48] These disruptions compounded logistical challenges for foreign legations and commercial interests, as documented in naval dispatches reporting ambushes on relief trains carrying provisions to besieged missionaries.[8] Russian imperial forces, stationed to safeguard the Chinese Eastern Railway, repelled multiple Boxer incursions near the Manchurian border, resulting in skirmishes that killed dozens of insurgents and prompted further troop deployments to secure Port Arthur and surrounding garrisons already under Russian lease since 1898.[49] Such engagements underscored the escalating volatility along imperial frontiers, with Russian commanders logging over 20 reported attacks on rail depots during the month.[48] Concurrently, the U.S. Senate engaged in deliberations over Philippine administration amid the protracted insurgency following the 1898 acquisition, where senators debated bills for military funding and provisional governance structures to suppress Filipino resistance led by Emilio Aguinaldo, with records indicating votes on appropriations exceeding $10 million for troop sustainment.[50] These discussions reflected strategic calculations for retaining control against rival powers, as articulated in congressional proceedings emphasizing naval basing advantages in the Pacific.[51] On February 5, the Hay-Pauncefote Treaty between the United States and Great Britain abrogated prior canal-sharing agreements, authorizing exclusive American construction of a Central American waterway and signaling assertive diplomatic positioning.[52]March
On March 13, British forces under Field Marshal Frederick Roberts captured Bloemfontein, the capital of the Orange Free State, marking a significant advance in the Second Boer War and prompting President Marthinus Steyn to flee the city the previous day.[53] This victory facilitated the annexation of the Orange Free State as the Orange River Colony, proclaimed by Roberts on March 15, reflecting Britain's strategic mobilization to consolidate control amid ongoing guerrilla resistance.[53] The U.S. Congress passed the Gold Standard Act on March 14, which President William McKinley signed into law the same day, defining the dollar's value at 25.8 grains of gold and requiring the Treasury to maintain parity among all forms of currency, thereby formalizing the gold standard and addressing monetary instability from the 1896 election's silverite debates.[54][55] Amid escalating anti-foreign violence by the Yihetuan (Boxers) in northern China, the United States initiated coordination for international relief efforts, with Secretary of State John Hay issuing diplomatic notes in March to European powers and Japan emphasizing preservation of China's territorial integrity while preparing naval and ground reinforcements, though the primary Seymour Expedition departed later in June.[56]April
In April 1900, the Boxer Rebellion intensified in northern China as militant societies, known as the Yihetuan or "Righteous Harmony Society," expanded their anti-foreign activities from Shandong province toward Beijing and Tianjin. These groups, initially suppressed by Qing authorities, gained tacit support amid widespread resentment against foreign economic privileges and missionary influence, leading to attacks on Chinese Christians and Western property. By mid-April, Boxers had disrupted rail lines and killed foreign missionaries, including the murder of American Presbyterian Eva Price and her associates near Taiyuan, escalating fears among expatriates. On April 6, the U.S. Navy gunboat USS Newark evacuated 36 foreign nationals from peril near the Chinese coast amid rising Boxer threats, highlighting early international naval interventions to protect legation staff and civilians.[8] Throughout the month, empirical reports from consular dispatches detailed Boxer advances, with militias numbering in the thousands converging on the capital, destroying infrastructure to isolate foreign enclaves. This prompted allied powers, including Britain, the United States, Germany, and Japan, to concentrate warships off Taku and concentrate troops, preparing for potential relief operations.[7] By April 25, Boxer forces had pressed closer to Beijing, besieging missionary compounds and prompting urgent telegrams from diplomats like British Minister Claude MacDonald requesting reinforcements, as Qing troops offered minimal resistance. These developments marked a shift from localized unrest to coordinated assaults, with Boxers employing guerrilla tactics and claiming supernatural invulnerability through ritual practices. Allied naval squadrons, totaling over 20 vessels by month's end, positioned for action, reflecting the powers' commitment to safeguarding treaty ports and extraterritorial rights amid the Qing court's ambivalence.[9]May
On May 1, 1900, an explosion at the Winter Quarters No. 4 coal mine near Scofield, Utah, triggered by ignited coal dust, killed at least 200 miners and boys through blast force and toxic gases, marking one of the deadliest mining accidents in U.S. history at the time.[57] [58] Throughout May 1900, the Boxer Rebellion in China escalated as Yihetuan (Boxer) militias, supported implicitly by Qing authorities after an initial condemnation was rescinded, intensified attacks on foreign missionaries, diplomats, and Chinese converts, destroying churches and railways while converging on Beijing, resulting in dozens of deaths among foreigners and Christians.[59] [8] On May 17, 1900, British imperial forces under Colonel Bryan Mahon relieved the 217-day Boer siege of Mafeking, breaking through Boer lines after a night march and skirmish that inflicted light casualties on the defenders while prompting Boer withdrawal, bolstering British morale in the Second Boer War.[60] On May 23, 1900, U.S. Army Sergeant William H. Carney received the Medal of Honor for seizing and protecting his regiment's colors under fire during the July 18, 1863, assault on Fort Wagner in the Civil War, making him the first African American soldier so honored despite wounds sustained in the action.[61] [62]June
In early June 1900, the Boxer Rebellion in China reached a critical stage as foreign legations in Beijing faced mounting attacks from Boxer militias, who believed themselves immune to Western bullets due to spiritual rituals. On June 10, an international relief expedition led by British Admiral Edward Seymour, comprising about 2,000 sailors and marines from eight nations, departed Tianjin by train and steamer to reinforce the legations, but encountered fierce resistance from Boxers and Qing forces, leading to heavy casualties and a retreat back to Tianjin by late June without reaching Beijing.[8][63] Defenders in the Beijing legations, numbering around 900 foreigners and Chinese Christians, held their positions through June using small arms such as rifles and machine guns to repel assaults, exploiting the Boxers' initial reliance on edged weapons despite some access to outdated firearms.[7] By mid-June, Boxers had entered Beijing en masse, killing foreign diplomats including the German minister on June 20 and initiating a formal 55-day siege of the diplomatic quarter on the same date, with legation guards maintaining defenses amid sporadic bombardment and infantry charges.[64] Elsewhere, British forces in the Second Boer War captured Pretoria, the capital of the Transvaal Republic, on June 5 after a brief siege, led by Lord Roberts with over 20,000 troops, though Boer commandos continued guerrilla resistance.[65] No major technological patents directly tied to mining safety, such as early carbide lamps, were issued in June, with significant developments like Frederick Baldwin's acetylene lamp patent following later in August.[66]July
On July 14, multinational allied forces, including troops from eight nations, captured the treaty port of Tianjin after intense fighting against Boxer rebels and Qing imperial army units, relieving the siege on foreign concessions and enabling further advances toward Beijing in the Boxer Rebellion campaign.[67][68] This victory, achieved through coordinated artillery barrages and infantry assaults, demonstrated the superiority of modern Western and Japanese weaponry over irregular Boxer militias armed primarily with melee weapons and outdated firearms, though it also highlighted logistical challenges in joint operations among rival powers.[69] On July 28, Louis Lassen, proprietor of Louis' Lunch in New Haven, Connecticut, served what is credited as the first hamburger: a grilled ground beef patty placed between two slices of bread to accommodate a customer's request for a portable meal.[70] This innovation, using vertical broiler-cooked meat without condiments to preserve simplicity, marked an early adaptation of ground beef sandwiches for American fast eating, though competing claims exist for similar preparations elsewhere.[71] On July 29, Gaetano Bresci, an Italian-American anarchist motivated by the Italian government's suppression of 1898 bread riots, assassinated King Umberto I during a public festival in Monza by firing multiple shots at close range as the king exited a restaurant.[72][73] The ease of Bresci's approach—mingling in an unsecured crowd without detection—exposed critical lapses in royal security protocols, reflecting broader monarchical complacency toward anarchist infiltration amid Europe's wave of regicidal attacks, including prior attempts on Umberto himself in 1897.[74] Bresci's act, financed partly through U.S. anarchist networks, intensified debates on radical threats and prompted stricter protective measures across European courts, though it failed to spark the predicted revolutionary upheaval.[75]August
In early August 1900, the Eight-Nation Alliance initiated the final advance on Beijing, with an allied force of approximately 20,000 troops departing Tianjin on August 4 to relieve the besieged foreign legations.[76] This expedition encountered resistance at the Battle of Beicang on August 5, where coordinated allied assaults defeated Qing and Boxer forces through disciplined infantry maneuvers and artillery support, demonstrating the technological and tactical advantages of Western and Japanese military training over irregular Chinese militias armed primarily with edged weapons and outdated tactics.[8] On August 14, the alliance's columns breached Beijing's outer walls and stormed the capital, lifting the 55-day siege of the international legations that had begun on June 20.[8] The success stemmed from empirical superiority in firepower—modern rifles, machine guns, and field artillery outmatched the defenders' capabilities—and better logistics enabling sustained operations, resulting in the rapid collapse of organized resistance within the city.[76] The U.S. contingent of roughly 2,500 soldiers and Marines, commanded by Major General Adna R. Chaffee, contributed significantly to the assault on key gates and the Imperial City.[76] Following the relief, allied troops, including American units, secured strategic positions across Beijing to prevent Boxer resurgence and maintain order, with U.S. forces occupying portions of the Tartar Wall and legation defenses amid ongoing skirmishes.[77] This phase underscored the alliance's commitment to protecting foreign interests without immediate partition demands, as evidenced by informal diplomatic understandings among commanders to prioritize stabilization over territorial grabs.[78]September
In September 1900, the multinational alliance's occupation of Beijing following the relief of the foreign legations in August gave rise to significant controversies over looting by foreign troops, who plundered imperial treasures from sites including the Old Summer Palace, with artifacts divided among the powers amid disputes over shares.[7] While full withdrawals awaited the Boxer Protocol of 1901, some allied contingents initiated partial pullbacks from outer areas as initial peace negotiations advanced under the Qing court.[8] The U.S. presidential campaign between incumbent Republican William McKinley and Democratic challenger William Jennings Bryan intensified during the month, centering on imperialism as a key issue, with Bryan decrying territorial expansion in the Philippines as a departure from American republican principles.[79] McKinley's platform defended recent acquisitions from the Spanish-American War as essential for national security and economic interests, contrasting Bryan's anti-expansionist stance that framed the election as a choice between republic and empire.[80] On September 17, the Commonwealth of Australia was officially proclaimed by the Governor-General in Melbourne, uniting the six colonies under a federal constitution ahead of the first national parliamentary elections in 1901, reflecting domestic political consolidation in the British Empire.[81] Concurrently, the U.S. anthracite coal miners' strike commenced on the same date, demanding higher wages and involving over 100,000 workers, which pressured operators amid the election season.[81]October
On October 6, Britain formally annexed the Orange Free State, renaming it the Orange River Colony, as part of the ongoing Second Boer War; this followed British military advances that subdued Boer resistance in the region, though guerrilla warfare persisted.[82] The annexation reflected Britain's strategy to consolidate control over former Boer republics, imposing martial law and restructuring administration to favor imperial governance.[83] In the aftermath of the Boxer Rebellion, United States Marines were withdrawn from China on October 11, concluding their deployment to protect legations and suppress anti-foreign uprisings in Beijing and surrounding areas.[8] The eight-nation alliance, including American forces, had relieved the siege of foreign legations in August, leading to the Qing court's capitulation; the withdrawal signaled a shift toward diplomatic negotiations for reparations and concessions, with the U.S. advocating an "Open Door" policy to limit territorial dismemberment of China.[8] On October 19, German physicist Max Planck presented his empirical formula for black-body radiation to the German Physical Society in Berlin, accurately fitting experimental spectral data across ultraviolet, visible, and infrared wavelengths where classical Rayleigh-Jeans and Wien approximations failed.[84] Derived from thermodynamic analysis of oscillators in thermal equilibrium, the formula incorporated a frequency-dependent energy distribution that resolved the "ultraviolet catastrophe" predicted by classical theory, though Planck initially viewed it as an interpolation without deeper physical interpretation.[84][85] This presentation laid groundwork for later quantum insights, as subsequent theoretical justification in December introduced discrete energy quanta.[85]November
On November 6, 1900, Republican incumbent President William McKinley secured reelection against Democratic challenger William Jennings Bryan in the United States presidential contest, a rematch of their 1896 matchup.[86] McKinley garnered 7,219,530 popular votes, comprising 51.6 percent of the total, while Bryan received 6,358,133 votes, or 45.5 percent; the remaining votes went to minor candidates, including the Prohibition Party's John G. Woolley with 208,914 votes.[86] In the Electoral College, McKinley and running mate Theodore Roosevelt amassed 292 votes to Bryan's 155, carrying key states like New York, Illinois, and Ohio amid a prosperous economy buoyed by the gold standard, which McKinley championed against Bryan's free-silver advocacy.[87] This outcome empirically validated McKinley's expansionist foreign policy, as Bryan's campaign emphasized anti-imperialism, criticizing the acquisition and governance of territories from the Spanish-American War, such as the Philippines, where U.S. forces had suppressed the independence movement.[86] Voters, benefiting from wartime gains and economic recovery, rejected Bryan's platform, signaling broad acceptance of American overseas engagement, including the recent dispatch of troops to quell the Boxer Rebellion in China earlier that year, where U.S. forces joined an international coalition to protect legations in Beijing.[87] In the ongoing aftermath of the Boxer Rebellion, which had seen anti-foreign uprisings suppressed by August 1900, allied powers maintained occupation of Beijing through November, initiating preliminary diplomatic exchanges with Qing representatives to demand reparations calibrated to verified losses in lives, property damage to legations, and missionary stations. These discussions laid groundwork for indemnity calculations, ultimately formalized in the 1901 Boxer Protocol at 450 million taels (roughly $333 million), distributed among the powers based on their documented claims, though exact November terms remained provisional amid Qing concessions to avert partition.December
On December 14, 1900, Max Planck delivered a seminal presentation to the German Physical Society in Berlin, articulating the quantum hypothesis to account for the spectrum of black-body radiation.[15] Classical electromagnetic theory, particularly the Rayleigh-Jeans law, had predicted an unrealistically infinite energy output at short wavelengths—termed the ultraviolet catastrophe—diverging sharply from experimental measurements of heated bodies like incandescent lamps.[14] Planck resolved this by positing that oscillators in the black body emit and absorb energy not continuously, but in discrete units or "quanta," with energy E = h\nu, where h is a universal constant (later Planck's constant, approximately $6.626 \times 10^{-34} J·s) and \nu is frequency; this interpolation formula precisely matched observed data across all wavelengths.[14] [88] Planck derived the hypothesis through combinatorial entropy considerations for N identical resonators sharing energy in multiples of quanta, yielding a distribution function that avoided infinities inherent in continuous models.[14] Initially, Planck regarded the quanta as a heuristic rather than a physical reality, stating it as "an act of despair" to fit data, yet the work marked the inception of quantum theory, challenging deterministic classical physics.[88] The constant h was determined empirically from radiation curves, with Planck's value refined over time through subsequent experiments.[14] By December 1900, combat operations in the Boxer Rebellion had concluded following the Eight-Nation Alliance's capture of Beijing in August, shifting focus to occupation, execution of rebel leaders (over 100 by allied forces), and stabilization under joint administration.[8] With the Yihetuan (Boxer) militias dispersed and Qing imperial support withdrawn, foreign legations were secured, enabling preliminary discussions on reparations—ultimately set at 450 million taels in the 1901 protocol—while select expeditionary units from nations like the United States initiated repatriation planning amid reduced hostilities.[7] This wind-down reflected the rebellion's suppression, though guerrilla remnants persisted into 1901, with total allied casualties exceeding 2,500 dead or wounded from the June-to-December campaign.[8]Notable Births

On May 1, 1900, an explosion at the Winter Quarters No. 4 coal mine near Scofield, Utah, triggered by ignited coal dust, killed at least 200 miners and boys through blast force and toxic gases, marking one of the deadliest mining accidents in U.S. history at the time.[57] [58] Throughout May 1900, the Boxer Rebellion in China escalated as Yihetuan (Boxer) militias, supported implicitly by Qing authorities after an initial condemnation was rescinded, intensified attacks on foreign missionaries, diplomats, and Chinese converts, destroying churches and railways while converging on Beijing, resulting in dozens of deaths among foreigners and Christians.[59] [8] On May 17, 1900, British imperial forces under Colonel Bryan Mahon relieved the 217-day Boer siege of Mafeking, breaking through Boer lines after a night march and skirmish that inflicted light casualties on the defenders while prompting Boer withdrawal, bolstering British morale in the Second Boer War.[60] On May 23, 1900, U.S. Army Sergeant William H. Carney received the Medal of Honor for seizing and protecting his regiment's colors under fire during the July 18, 1863, assault on Fort Wagner in the Civil War, making him the first African American soldier so honored despite wounds sustained in the action.[61] [62]June
In early June 1900, the Boxer Rebellion in China reached a critical stage as foreign legations in Beijing faced mounting attacks from Boxer militias, who believed themselves immune to Western bullets due to spiritual rituals. On June 10, an international relief expedition led by British Admiral Edward Seymour, comprising about 2,000 sailors and marines from eight nations, departed Tianjin by train and steamer to reinforce the legations, but encountered fierce resistance from Boxers and Qing forces, leading to heavy casualties and a retreat back to Tianjin by late June without reaching Beijing.[8][63] Defenders in the Beijing legations, numbering around 900 foreigners and Chinese Christians, held their positions through June using small arms such as rifles and machine guns to repel assaults, exploiting the Boxers' initial reliance on edged weapons despite some access to outdated firearms.[7] By mid-June, Boxers had entered Beijing en masse, killing foreign diplomats including the German minister on June 20 and initiating a formal 55-day siege of the diplomatic quarter on the same date, with legation guards maintaining defenses amid sporadic bombardment and infantry charges.[64] Elsewhere, British forces in the Second Boer War captured Pretoria, the capital of the Transvaal Republic, on June 5 after a brief siege, led by Lord Roberts with over 20,000 troops, though Boer commandos continued guerrilla resistance.[65] No major technological patents directly tied to mining safety, such as early carbide lamps, were issued in June, with significant developments like Frederick Baldwin's acetylene lamp patent following later in August.[66]July
On July 14, multinational allied forces, including troops from eight nations, captured the treaty port of Tianjin after intense fighting against Boxer rebels and Qing imperial army units, relieving the siege on foreign concessions and enabling further advances toward Beijing in the Boxer Rebellion campaign.[67][68] This victory, achieved through coordinated artillery barrages and infantry assaults, demonstrated the superiority of modern Western and Japanese weaponry over irregular Boxer militias armed primarily with melee weapons and outdated firearms, though it also highlighted logistical challenges in joint operations among rival powers.[69] On July 28, Louis Lassen, proprietor of Louis' Lunch in New Haven, Connecticut, served what is credited as the first hamburger: a grilled ground beef patty placed between two slices of bread to accommodate a customer's request for a portable meal.[70] This innovation, using vertical broiler-cooked meat without condiments to preserve simplicity, marked an early adaptation of ground beef sandwiches for American fast eating, though competing claims exist for similar preparations elsewhere.[71] On July 29, Gaetano Bresci, an Italian-American anarchist motivated by the Italian government's suppression of 1898 bread riots, assassinated King Umberto I during a public festival in Monza by firing multiple shots at close range as the king exited a restaurant.[72][73] The ease of Bresci's approach—mingling in an unsecured crowd without detection—exposed critical lapses in royal security protocols, reflecting broader monarchical complacency toward anarchist infiltration amid Europe's wave of regicidal attacks, including prior attempts on Umberto himself in 1897.[74] Bresci's act, financed partly through U.S. anarchist networks, intensified debates on radical threats and prompted stricter protective measures across European courts, though it failed to spark the predicted revolutionary upheaval.[75]August
In early August 1900, the Eight-Nation Alliance initiated the final advance on Beijing, with an allied force of approximately 20,000 troops departing Tianjin on August 4 to relieve the besieged foreign legations.[76] This expedition encountered resistance at the Battle of Beicang on August 5, where coordinated allied assaults defeated Qing and Boxer forces through disciplined infantry maneuvers and artillery support, demonstrating the technological and tactical advantages of Western and Japanese military training over irregular Chinese militias armed primarily with edged weapons and outdated tactics.[8] On August 14, the alliance's columns breached Beijing's outer walls and stormed the capital, lifting the 55-day siege of the international legations that had begun on June 20.[8] The success stemmed from empirical superiority in firepower—modern rifles, machine guns, and field artillery outmatched the defenders' capabilities—and better logistics enabling sustained operations, resulting in the rapid collapse of organized resistance within the city.[76] The U.S. contingent of roughly 2,500 soldiers and Marines, commanded by Major General Adna R. Chaffee, contributed significantly to the assault on key gates and the Imperial City.[76] Following the relief, allied troops, including American units, secured strategic positions across Beijing to prevent Boxer resurgence and maintain order, with U.S. forces occupying portions of the Tartar Wall and legation defenses amid ongoing skirmishes.[77] This phase underscored the alliance's commitment to protecting foreign interests without immediate partition demands, as evidenced by informal diplomatic understandings among commanders to prioritize stabilization over territorial grabs.[78]September
In September 1900, the multinational alliance's occupation of Beijing following the relief of the foreign legations in August gave rise to significant controversies over looting by foreign troops, who plundered imperial treasures from sites including the Old Summer Palace, with artifacts divided among the powers amid disputes over shares.[7] While full withdrawals awaited the Boxer Protocol of 1901, some allied contingents initiated partial pullbacks from outer areas as initial peace negotiations advanced under the Qing court.[8] The U.S. presidential campaign between incumbent Republican William McKinley and Democratic challenger William Jennings Bryan intensified during the month, centering on imperialism as a key issue, with Bryan decrying territorial expansion in the Philippines as a departure from American republican principles.[79] McKinley's platform defended recent acquisitions from the Spanish-American War as essential for national security and economic interests, contrasting Bryan's anti-expansionist stance that framed the election as a choice between republic and empire.[80] On September 17, the Commonwealth of Australia was officially proclaimed by the Governor-General in Melbourne, uniting the six colonies under a federal constitution ahead of the first national parliamentary elections in 1901, reflecting domestic political consolidation in the British Empire.[81] Concurrently, the U.S. anthracite coal miners' strike commenced on the same date, demanding higher wages and involving over 100,000 workers, which pressured operators amid the election season.[81]October
On October 6, Britain formally annexed the Orange Free State, renaming it the Orange River Colony, as part of the ongoing Second Boer War; this followed British military advances that subdued Boer resistance in the region, though guerrilla warfare persisted.[82] The annexation reflected Britain's strategy to consolidate control over former Boer republics, imposing martial law and restructuring administration to favor imperial governance.[83] In the aftermath of the Boxer Rebellion, United States Marines were withdrawn from China on October 11, concluding their deployment to protect legations and suppress anti-foreign uprisings in Beijing and surrounding areas.[8] The eight-nation alliance, including American forces, had relieved the siege of foreign legations in August, leading to the Qing court's capitulation; the withdrawal signaled a shift toward diplomatic negotiations for reparations and concessions, with the U.S. advocating an "Open Door" policy to limit territorial dismemberment of China.[8] On October 19, German physicist Max Planck presented his empirical formula for black-body radiation to the German Physical Society in Berlin, accurately fitting experimental spectral data across ultraviolet, visible, and infrared wavelengths where classical Rayleigh-Jeans and Wien approximations failed.[84] Derived from thermodynamic analysis of oscillators in thermal equilibrium, the formula incorporated a frequency-dependent energy distribution that resolved the "ultraviolet catastrophe" predicted by classical theory, though Planck initially viewed it as an interpolation without deeper physical interpretation.[84][85] This presentation laid groundwork for later quantum insights, as subsequent theoretical justification in December introduced discrete energy quanta.[85]November
On November 6, 1900, Republican incumbent President William McKinley secured reelection against Democratic challenger William Jennings Bryan in the United States presidential contest, a rematch of their 1896 matchup.[86] McKinley garnered 7,219,530 popular votes, comprising 51.6 percent of the total, while Bryan received 6,358,133 votes, or 45.5 percent; the remaining votes went to minor candidates, including the Prohibition Party's John G. Woolley with 208,914 votes.[86] In the Electoral College, McKinley and running mate Theodore Roosevelt amassed 292 votes to Bryan's 155, carrying key states like New York, Illinois, and Ohio amid a prosperous economy buoyed by the gold standard, which McKinley championed against Bryan's free-silver advocacy.[87] This outcome empirically validated McKinley's expansionist foreign policy, as Bryan's campaign emphasized anti-imperialism, criticizing the acquisition and governance of territories from the Spanish-American War, such as the Philippines, where U.S. forces had suppressed the independence movement.[86] Voters, benefiting from wartime gains and economic recovery, rejected Bryan's platform, signaling broad acceptance of American overseas engagement, including the recent dispatch of troops to quell the Boxer Rebellion in China earlier that year, where U.S. forces joined an international coalition to protect legations in Beijing.[87] In the ongoing aftermath of the Boxer Rebellion, which had seen anti-foreign uprisings suppressed by August 1900, allied powers maintained occupation of Beijing through November, initiating preliminary diplomatic exchanges with Qing representatives to demand reparations calibrated to verified losses in lives, property damage to legations, and missionary stations. These discussions laid groundwork for indemnity calculations, ultimately formalized in the 1901 Boxer Protocol at 450 million taels (roughly $333 million), distributed among the powers based on their documented claims, though exact November terms remained provisional amid Qing concessions to avert partition.December
On December 14, 1900, Max Planck delivered a seminal presentation to the German Physical Society in Berlin, articulating the quantum hypothesis to account for the spectrum of black-body radiation.[15] Classical electromagnetic theory, particularly the Rayleigh-Jeans law, had predicted an unrealistically infinite energy output at short wavelengths—termed the ultraviolet catastrophe—diverging sharply from experimental measurements of heated bodies like incandescent lamps.[14] Planck resolved this by positing that oscillators in the black body emit and absorb energy not continuously, but in discrete units or "quanta," with energy E = h\nu, where h is a universal constant (later Planck's constant, approximately $6.626 \times 10^{-34} J·s) and \nu is frequency; this interpolation formula precisely matched observed data across all wavelengths.[14] [88] Planck derived the hypothesis through combinatorial entropy considerations for N identical resonators sharing energy in multiples of quanta, yielding a distribution function that avoided infinities inherent in continuous models.[14] Initially, Planck regarded the quanta as a heuristic rather than a physical reality, stating it as "an act of despair" to fit data, yet the work marked the inception of quantum theory, challenging deterministic classical physics.[88] The constant h was determined empirically from radiation curves, with Planck's value refined over time through subsequent experiments.[14] By December 1900, combat operations in the Boxer Rebellion had concluded following the Eight-Nation Alliance's capture of Beijing in August, shifting focus to occupation, execution of rebel leaders (over 100 by allied forces), and stabilization under joint administration.[8] With the Yihetuan (Boxer) militias dispersed and Qing imperial support withdrawn, foreign legations were secured, enabling preliminary discussions on reparations—ultimately set at 450 million taels in the 1901 protocol—while select expeditionary units from nations like the United States initiated repatriation planning amid reduced hostilities.[7] This wind-down reflected the rebellion's suppression, though guerrilla remnants persisted into 1901, with total allied casualties exceeding 2,500 dead or wounded from the June-to-December campaign.[8]Date Unknown
Sadie Goodson, an American jazz pianist and singer active in the New Orleans scene, was born circa 1900; she collaborated with musicians including her sister Billie Pierce and performed traditional jazz repertoire.[89] Zizwezenyanga Qwabe, a Zulu wood carver from South Africa known for depicting ethnographic subjects such as warriors and daily village life, was born around 1900 and worked primarily in the 1920s–1940s.[90] John Gordon Leak, a Zuni silversmith from New Mexico, was born circa 1900 and gained recognition for intricate jewelry incorporating traditional Pueblo motifs like inlay and overlay techniques.[91] These figures represent contributions in music and indigenous arts where precise birth records were limited due to historical documentation practices in their respective communities.Notable Deaths
January–June
On January 20, John Ruskin, the influential English art critic, writer, and social reformer, died at age 80 in Coniston, England, from complications of influenza.[92] His passing marked a significant loss to Victorian intellectual circles, where his works like Modern Painters and The Stones of Venice had profoundly shaped discourse on aesthetics, architecture, and ethics, influencing subsequent generations in art history and cultural critique.[93] On March 6, Gottlieb Daimler, the German engineer and industrialist pivotal to early automotive development, died at age 65 in Cannstatt, Germany, likely from heart-related issues following prolonged illness.[94] Daimler's innovations, including the high-speed internal combustion engine and the first practical motorcycle in 1885, laid foundational advancements in transportation technology, accelerating industrial progress and enabling modern mobility.[95] Richard Doddridge Blackmore, English novelist known for Lorna Doone, died on March 20 at age 75 in Teddington, England, after suffering from a long-term illness. His death diminished contributions to romantic literature, where his detailed portrayals of rural life and historical settings had enriched narrative traditions. On April 30, John Luther "Casey" Jones, the American locomotive engineer, perished at age 37 in a collision near Vaughan, Mississippi, when his train struck a stalled freight; he remained at the controls to brake, saving his crew but sacrificing himself.[96] This incident, while tragic, underscored risks in expanding rail networks essential to economic growth, later inspiring folklore that highlighted human resilience in industrial labor.[97] On May 5, Ivan Aivazovsky, the prolific Russian-Armenian marine painter renowned for over 6,000 works depicting seascapes, died at age 82 in Feodosia from heart failure. His demise represented a setback for Romantic art, as his mastery of light and motion on water influenced maritime representation and preserved visual records of naval history. On June 5, Stephen Crane, the American author of The Red Badge of Courage and innovative naturalist fiction, died at age 28 in Badenweiler, Germany, from advanced tuberculosis exacerbated by prior exposures.[98] Crane's early death curtailed a promising trajectory in literature, where his realistic war depictions and psychological insights had pioneered modernist techniques, impacting narrative realism and journalism.[99] These losses in diverse fields—art, engineering, literature, and transportation—deprived advancing societies of key contributors during a period of rapid industrialization and cultural evolution, with verifiable causes rooted in infectious diseases or occupational hazards prevalent at the time.July–December
The most politically significant death in the latter half of 1900 was that of Umberto I, King of Italy, on July 29 in Monza, where he was shot by Gaetano Bresci, an Italian-born anarchist who had emigrated to the United States.[72][73] Bresci's act was motivated by retribution for the Italian government's violent suppression of worker demonstrations, including the 1898 Milan bread riots under Umberto's reign, which resulted in hundreds of deaths.[100] This assassination, the third attempt on Umberto's life, exposed systemic vulnerabilities in monarchical security protocols amid the transnational spread of anarchist ideology, influencing subsequent European discussions on protecting political figures from ideological extremists.[101] On August 25, Friedrich Nietzsche, the influential German philosopher known for works critiquing traditional morality and religion, died in Weimar at age 55 from complications of pneumonia following a series of strokes that had incapacitated him since 1889.[102] Other notable figures who died during this period included Collis P. Huntington, American railroad magnate and key promoter of the Central Pacific Railroad, on August 13 from heart-related issues.[103] Étienne Lenoir, Belgian-French inventor of an early internal combustion engine, passed away on August 4.[104] These deaths, while not directly tied to security failures, reflect the era's toll on industrial and intellectual pioneers.Demographics and Population
Global Population Estimates
The global population in 1900 is estimated at approximately 1.65 billion, reflecting a significant increase from earlier centuries due to improvements in agricultural productivity and early public health measures.[105] Historical estimates vary, with ranges cited between 1.55 billion and 1.76 billion based on compilations of national censuses and demographic reconstructions.[106]| Continent/Region | Population (millions) |
|---|---|
| Asia | 947 |
| Europe | 295 |
| Africa | 133 |
| North America | 82 |
| South America | 38 |
| Oceania | 6 |
Regional and National Trends
The Twelfth United States Census, conducted as of June 1, 1900, recorded a total population of 76,212,168, marking a 21.01 percent increase from the 1890 figure of 62,947,714.[28] This growth was fueled by high immigration rates, with foreign-born residents comprising 13.6 percent of the population, or approximately 10.3 million individuals, concentrated in urban industrial centers.[107] Urban areas, defined as places with 2,500 or more inhabitants, housed 30.2 million people, or 39.6 percent of the total, reflecting rapid migration from rural regions and overseas, particularly from southern and eastern Europe.[28] In Europe, national censuses revealed higher population densities compared to the expanding Americas. The German Empire's 1900 census enumerated 56,367,178 residents, with dense industrial regions in the Ruhr Valley driving urbanization.[108] The United Kingdom's 1901 census counted 41,681,030 people across England, Wales, Scotland, and Ireland, where over 77 percent lived in urban settings amid ongoing emigration to the Americas. Russia's 1897 census, the most recent comprehensive count, reported 125,640,021 for the empire excluding Finland, highlighting vast rural densities in European territories despite internal migrations eastward.[109] These figures underscored Europe's role as a net exporter of population, with millions departing for opportunities in the New World. Across the Americas, demographic expansion contrasted Europe's relative density. Canada's 1901 census tallied 5,371,315 inhabitants, bolstered by immigration and settlement in prairie provinces. In Australia, the 1901 census—following federation—registered 3,773,801 people, with urbanization accelerating in coastal cities like Sydney and Melbourne due to internal migration from rural goldfields and British inflows.[110] This pattern of overseas settlement and urban pull mirrored the U.S., where westward expansion continued, adding states like Oklahoma to the union by 1907 but rooted in 1900 trends of frontier settlement.[28] In China, no formal national census occurred in 1900, but estimates placed the population at around 400 million, with the Boxer Rebellion (1899–1901) inflicting localized demographic shocks in northern provinces through combat deaths, reprisals, and displacement estimated in the tens of thousands.[111] The uprising's violence, including sieges in Beijing, disrupted rural communities and exacerbated famine risks, though overall national figures showed resilience amid prior upheavals like the Taiping Rebellion's lingering effects.[112] Reparations imposed post-rebellion, scaled to population size, strained resources without altering broader growth trajectories significantly by year's end.| Country/Region | Population | Census/Estimate Year | Key Trend |
|---|---|---|---|
| United States | 76,212,168 | 1900 | Urbanization and immigration-driven growth[28] |
| German Empire | 56,367,178 | 1900 | High industrial density[108] |
| United Kingdom | 41,681,030 | 1901 | Emigration and urban concentration |
| Russian Empire (excl. Finland) | 125,640,021 | 1897 | Rural expanse with European focus[109] |
| Australia | 3,773,801 | 1901 | Coastal urbanization post-federation[110] |
| China (estimate) | ~400,000,000 | 1900 | Localized disruptions from rebellion[111] |
