Third Period
The Third Period was a strategic doctrine formulated by the Communist International (Comintern) at its Sixth World Congress in Moscow during the summer of 1928, designating the contemporary historical phase as the terminal crisis of world capitalism, fraught with economic collapse, fascist ascendancy, and the brink of imperialist war, which demanded that affiliated communist parties launch immediate revolutionary assaults on bourgeois states while denouncing social democratic movements as the primary social buttress of capitalism—termed "social fascism"—and thus unfit for any tactical collaboration.[1] This ultra-sectarian orientation, formalized further at the Comintern's Executive Committee plenum in July 1929, prioritized the mobilization of communist vanguards for spontaneous uprisings and mass strikes over broader working-class alliances, reflecting Joseph Stalin's consolidation of control over the organization through ideological enforcement and purges of dissenting leaders.[1] The policy's most notorious consequence unfolded in Germany, where the Communist Party of Germany (KPD), adhering rigidly to the rejection of united fronts with the Social Democratic Party (SPD), fragmented the antifascist opposition and facilitated Adolf Hitler's accession to power in 1933, culminating in the rapid suppression and exile of communist forces amid widespread arrests and executions.[1][2] Abandoned by 1935 in favor of the Popular Front strategy amid escalating global threats, the Third Period exemplified the Comintern's oscillation between adventurism and opportunism, yielding electoral gains for some parties but overall isolation from mass movements and strategic defeats that underscored the perils of dogmatic internationalism divorced from local contingencies.[1]Origins and Theoretical Foundations
Adoption by the Comintern
The Communist International (Comintern) formally adopted the Third Period strategy at its Sixth World Congress, convened in Moscow from July 17 to September 1, 1928.[3] The congress, attended by 515 delegates representing 64 communist parties and organizations from across the globe, marked a pivotal shift in Comintern policy, declaring the end of the post-World War I capitalist stabilization phase (the Second Period, roughly 1924–1928) and the onset of a new era of intensified global economic crisis and revolutionary upheaval.[4] This adoption reflected the Comintern's assessment that the world economy had entered a terminal stage of decay, driven by factors such as the onset of the Great Depression precursors and perceived weaknesses in bourgeois democracies, necessitating a return to ultra-revolutionary tactics over prior collaborative approaches.[5] Nikolai Bukharin, then a leading figure in the Comintern leadership, presented the draft Programme of the Communist International on August 6, 1928, which encapsulated the Third Period framework by outlining three successive historical phases since 1914: the first of war and initial revolutions (1914–1923), the second of partial stabilization, and the third—beginning in 1928—as one of capitalism's final collapse and proletarian advance.[6] The programme, debated over several weeks amid internal factional tensions, was ultimately approved on August 27, 1928, embedding the Third Period as the doctrinal basis for Comintern directives to national sections, emphasizing independent proletarian action against all reformist elements.[3] This endorsement aligned with Joseph Stalin's consolidating influence within the Soviet leadership, which pressured the Comintern to purge "rightist" deviations favoring economic accommodation, though Bukharin initially defended the programme before his later opposition.[5] The congress resolutions, including those on tactics and the international situation, operationalized the Third Period by instructing communist parties to intensify class warfare, form independent workers' governments, and combat social democracy as a variant of fascism, thereby abrogating earlier united front experiments.[4] Approximately 200 amendments were proposed to the draft programme, reflecting debates on the timing and intensity of the crisis, but the final text affirmed 1928 as the demarcation for the new period, influencing Comintern strategy until its reversal at the Seventh Congress in 1935.[6] Scholarly analyses attribute the adoption partly to Soviet domestic priorities, where the policy paralleled Stalin's forced collectivization and rapid industrialization, exporting an aggressive line to affiliates despite uneven global conditions.[7]Definition of the "Third Period" Concept
The "Third Period" refers to the strategic and ideological framework adopted by the Communist International (Comintern) at its Sixth World Congress, convened in Moscow from July 17 to September 1, 1928, which characterized the global historical moment as the onset of capitalism's terminal crisis.[8] This doctrine divided post-World War I developments into three successive phases: the first (roughly 1917–1921) as a period of revolutionary upsurge following the Bolshevik Revolution; the second (1921–1928) as one of partial capitalist stabilization amid economic recovery and relative class truce; and the third, commencing in 1928, as an era of acute, irreversible contradictions in the capitalist system, marked by intensifying economic crises, the collapse of bourgeois democracies, the rise of fascism, and the sharpening preconditions for proletarian revolution or imperialist war.[9] [10] Central to the concept was the assertion that the end of the Soviet New Economic Policy in 1928 signaled broader global destabilization, with overproduction, falling prices, and mass unemployment heralding capitalism's "final phase" rather than mere cyclical downturns.[11] Comintern theorists, influenced by Nikolai Bukharin's report on the international situation, argued that this period demanded intensified class struggle, rejecting compromises with reformist forces and prioritizing independent communist mobilization to exploit the purported revolutionary opportunities.[8] The policy remained in effect until the Seventh Comintern Congress in 1935, when it was superseded by the Popular Front strategy amid escalating fascist threats.[10] This framing, while rooted in Marxist analysis of capitalist contradictions, was critiqued even contemporaneously for overemphasizing conjunctural crises as structurally terminal without sufficient empirical grounding in varying national conditions, leading to tactical adventurism in communist parties worldwide.[11] Nonetheless, it formalized the Comintern's ultra-left orientation during a decade of profound economic turmoil, including the Great Depression's onset in 1929.[9]Theoretical Justifications and Influences
The Third Period doctrine was grounded in the Comintern's interpretation of Marxist-Leninist crisis theory, positing that capitalism, as the highest stage of imperialism outlined by Lenin in 1917, was undergoing its terminal decomposition. This view held that the uneven development of global capitalism had exhausted temporary stabilizations, leading to an acute phase of economic collapse, sharpened class antagonisms, and the ascendancy of fascist regimes as the bourgeoisie resorted to overt dictatorship to suppress proletarian resistance. The framework divided post-World War I history into sequential phases: an initial revolutionary upsurge immediately after 1917, a subsequent period of partial capitalist recovery through 1927, and the onset of the third period by 1928, characterized by insoluble contradictions between expanding productive forces and contracting markets under monopolistic control. Central to these justifications was the Comintern's 1928 programme, drafted primarily by Nikolai Bukharin under Stalin's oversight and adopted at the Sixth World Congress (17 July–1 September 1928), which analyzed the Wall Street Crash precursors and global economic indicators—such as falling commodity prices and industrial overproduction—as empirical signs of systemic breakdown. The congress resolutions emphasized that this crisis would catalyze mass radicalization and revolutionary opportunities, necessitating uncompromising class-against-class tactics to expose reformist illusions and build Bolshevik-style parties. Influences included Lenin's earlier Comintern congress addresses on tactical flexibility amid crisis, but adapted rigidly to predict imminent proletarian victory, diverging from empirical realities where revolutions failed to materialize in major capitalist states.[9][12] Stalin's theoretical contributions reinforced the doctrine by linking international dynamics to Soviet priorities, arguing in internal party documents that the third period validated accelerated socialist construction in the USSR as the vanguard against fascist encirclement. This synthesis prioritized causal chains from imperialist decay to domestic upheavals, drawing on dialectical materialism to dismiss social democratic alliances as capitulationist, though critics like Trotsky later attributed its ultra-leftism to bureaucratic distortions rather than pure theoretical fidelity. The approach reflected a mechanical application of crisis periodicity, underestimating capitalism's adaptive resilience as evidenced by subsequent New Deal policies and delayed fascist defeats.[13][11]Domestic Implementation in the Soviet Union
Alignment with Stalin's Consolidation of Power
The adoption of the Third Period doctrine at the Communist International's (Comintern) Sixth World Congress, convened from July 17 to September 1, 1928, occurred amid Joseph Stalin's maneuvering against the Right Opposition led by Nikolai Bukharin and Alexei Rykov within the Soviet Communist Party (CPSU).[14] [8] This congress proclaimed the onset of a final crisis of capitalism, demanding heightened class confrontation globally, which paralleled Stalin's domestic pivot away from the New Economic Policy (NEP)—a partial market concession ended in 1928—toward aggressive collectivization of agriculture and the First Five-Year Plan for industrialization launched in 1929.[14] [15] Stalin explicitly endorsed the Third Period framework in his writings, arguing it necessitated uncompromising struggle against all perceived capitalist agents, including social democrats branded as "social fascists," thereby ideologically arming the CPSU against internal moderates advocating gradualism.[14] This international ultra-left shift reinforced Stalin's consolidation by subordinating the Comintern more directly to CPSU authority under his control. Prior Comintern leaders like Grigory Zinoviev (removed in 1926) and Bukharin (chairman until 1929) had favored tactical flexibility, such as limited cooperation with non-communist forces; the Third Period's rejection of such approaches eliminated ideological space for oppositionists sympathetic to these views.[8] Stalin's loyalist Vyacheslav Molotov, previously uninvolved in Comintern affairs, assumed a dominant role in its executive by late 1928, streamlining directives from Moscow and purging dissenters in foreign parties to mirror Soviet internal discipline.[8] The policy's emphasis on imminent revolution justified domestic repressions, including the dekulakization campaign that liquidated over 1.8 million peasant households as "class enemies" between 1929 and 1933, framing these as necessary defenses of socialism against capitalist encirclement—a narrative extended abroad to delegitimize rivals.[15] By aligning Comintern strategy with Stalin's "left turn," the Third Period facilitated the isolation of Trotskyist and Bukharinist factions internationally, as foreign communists were compelled to denounce social democrats and centrists, precluding alliances that might have amplified Soviet dissident voices.[8] This synchronization peaked with Bukharin's ouster from the Comintern chairmanship in 1929 and his expulsion from the CPSU Politburo, solidifying Stalin's unchallenged dominance by 1930.[14] The doctrine thus served not merely as economic prognostication but as a tool for bureaucratic centralization, prioritizing Soviet state imperatives over global revolutionary prospects, with Comintern sections compelled to echo CPSU line on pain of dissolution or execution of leaders.[8]Integration with Soviet Economic and Purge Policies
The Third Period doctrine, formalized at the Comintern's Sixth World Congress from July to September 1928, aligned closely with the Soviet Union's shift to the First Five-Year Plan, approved by the Fifteenth Party Congress in December 1927 and launched on October 1, 1928, which prioritized heavy industry and ended the New Economic Policy's market elements.[16] This economic strategy demanded resource extraction from agriculture through forced collectivization, beginning in earnest in 1929, to fund industrialization amid expectations of capitalist collapse and war, mirroring the Comintern's thesis of a global revolutionary crisis.[8] The policy's internal disruptions, including peasant resistance and the 1932–1933 famine that killed millions, were framed as necessary sacrifices for building socialism in one country, reinforcing the Third Period's rejection of gradualism.[17] Stalin's consolidation intertwined Comintern ultra-leftism with domestic purges starting in 1928, targeting the Right Opposition for opposing rapid collectivization and favoring continued NEP concessions.[18] Leaders like Nikolai Bukharin, Alexei Rykov, and Mikhail Tomsky were expelled from the Politburo in November 1929 and faced further isolation by 1930, accused of ideological deviation akin to the social fascism denounced internationally.[8] This period saw over 100,000 party members scrutinized and thousands removed by 1933 for alleged sabotage or kulak sympathies, with Third Period rhetoric providing justification by portraying moderates as agents of imperialist encirclement.[18] The synergy extended to subordinating Comintern activities to Soviet security needs, as the doctrine's emphasis on imminent revolution rationalized internal repression to eliminate potential fifth columns.[17] By equating domestic opposition with foreign threats, Stalin purged Comintern personnel suspected of insufficient loyalty, such as critical figures in foreign sections, paving the way for later escalations in the mid-1930s.[8] This integration transformed the Comintern into an instrument of Soviet state policy, prioritizing defense of the USSR over independent revolutionary initiatives abroad.[8]International Application and Strategies
Ultra-Left Tactics in Communist Parties
The ultra-left tactics adopted by communist parties under Comintern guidance during the Third Period (1928–1935) emphasized uncompromising "class against class" confrontation, rejecting any tactical alliances with social democratic or reformist elements deemed obstacles to proletarian revolution. These tactics, rooted in the Sixth World Congress's assessment of an impending final capitalist crisis, directed parties to prioritize independent actions such as forming rival "red" trade unions, launching spontaneous strikes without coordination, and mobilizing paramilitary-style self-defense units to assert dominance over the working class.[19] The Comintern's resolutions urged parties to expose social democrats as "social fascists"—the purported moderate wing of fascism—thereby justifying aggressive opposition to them as the principal enemy within the labor movement, even amid rising fascist threats.[12] In Germany, the Communist Party (KPD) exemplified these tactics through systematic vilification and physical assaults on the Social Democratic Party (SPD), which it accused of betraying workers via collaboration with bourgeois democracy. KPD leader Ernst Thälmann's directives led to initiatives like the Antifaschistische Aktion in 1932, ostensibly anti-Nazi but primarily targeting SPD-affiliated trade unions and functionaries as "fascist agents," resulting in street battles that fragmented anti-fascist resistance; for instance, KPD forces disrupted SPD-led demonstrations and refused joint defenses against Nazi SA attacks, contributing to over 100 fatalities in Berlin clashes between communists and social democrats in 1931 alone.[20] The party's independent "wildcat" strikes, such as those in the Ruhr region in 1931–1932, bypassed SPD-dominated unions to recruit militants but alienated broader workers, with KPD membership peaking at around 360,000 in 1932 while failing to halt the Nazis' electoral surge from 18.3% in 1930 to 37.3% in March 1933.[21] Similar patterns emerged in France, where the French Communist Party (PCF) pursued isolationist strategies, denouncing the Socialist SFIO as complicit in "social fascist" policies and organizing separate mass actions that undermined potential unity. PCF tactics included boycotting joint union efforts and promoting autonomous "unitary" unions, which captured only a fraction of the workforce; by 1932, amid economic depression, the PCF's electoral support had dwindled to 8% of the vote, reflecting worker disaffection from its refusal to collaborate on unemployment protests or anti-fascist mobilizations.[22] In Britain, the Communist Party of Great Britain (CPGB) engaged in ultra-left adventurism, such as unauthorized factory occupations and calls for "independent leadership" in the 1929 general strike aftermath, leading to expulsions from mainstream unions and a stagnant membership of under 3,000 by 1930.[8] These approaches, enforced via Comintern purges of "rightist" leaders, prioritized ideological purity over pragmatic mass work, fostering adventurist impulses like premature calls for armed uprisings in localized disputes.[23] Critics within the communist movement, including Leon Trotsky, argued that such tactics reflected bureaucratic degeneration under Stalinist influence, substituting ultraleft posturing for genuine revolutionary strategy and accelerating fascist gains by dividing the proletariat; Trotsky documented instances where Comintern envoys overrode local assessments to impose "leftist" errors, as in the KPD's mishandling of 1931 Prussian referendum campaigns against SPD governance.[12] Empirical outcomes bore this out: across Europe, communist parties experienced organizational isolation, with collective vote shares for KPD and PCF stagnating or declining relative to fascists between 1928 and 1933, underscoring the tactics' failure to harness crisis-induced radicalization.[20]Refusal of United Fronts with Social Democrats
The Comintern's Third Period policy explicitly prohibited communist parties from entering united fronts with social democratic organizations at the leadership level, designating social democrats as the chief obstacle to proletarian revolution. At the Sixth World Congress in July–September 1928, resolutions framed the era as one of acute capitalist crisis demanding intensified class struggle, with social democracy cast as "the moderate variant of fascism" that sustained bourgeois rule through reformist illusions and collaboration with capitalist states. This doctrinal shift, influenced by Stalin's emphasis on social democracy's role in stabilizing capitalism, overrode earlier tactical flexibility from the 1920s united front initiatives, mandating instead a "united front from below" to siphon social democratic workers away from their parties without compromising on principles like armed insurrection or Soviet defense.[24] In practice, this refusal prioritized denunciation of social democrats as "social fascists"—a term codified in Comintern directives portraying them as fascism's "twin brother" for allegedly paving the way to reaction via participation in bourgeois governments. Communist parties were instructed to combat social democratic influence in trade unions and workplaces aggressively, often through dual unionism or strikes against social democratic-led actions, while dismissing fascism as a secondary threat that would collapse amid the predicted revolutionary upsurge.[8] The policy's rigidity stemmed from the Comintern's belief that alliances with "opportunists" would dilute revolutionary purity, as articulated in the 1928 Programme of the Communist International, which called for exposing social democracy's "treachery" before turning to fascist elimination post-revolution.[24] Germany exemplified the policy's application, where the KPD, under Ernst Thälmann's leadership aligned with Moscow, rebuffed multiple SPD initiatives amid Weimar's instability. In October 1931, SPD chairman Otto Wels proposed a joint front against National Socialism following Prussian government clashes, but the KPD countered with demands for the SPD to exit coalitions, arm proletarian units, and reject parliamentarism—conditions the Comintern enforced to avoid legitimizing social democratic "reformism," resulting in impasse.[25] Similar rejections occurred in 1932, including during the Berlin transport strike where KPD-SPD divisions prevented coordinated resistance to Nazi street violence, with Comintern envoys overruling KPD moderates advocating tactical unity.[8] This stance extended internationally: in Britain, the CPGB labeled the Labour Party social fascist and boycotted joint anti-fascist efforts; in Czechoslovakia, KSČ splits mirrored German patterns, fracturing left opposition to rising authoritarianism.[26] The refusal's theoretical underpinning rested on empirical observations of social democrats' wartime support for imperialism and post-war stabilization roles, yet it disregarded tactical necessities in fascism's ascent, as later critiqued in Comintern self-assessments. By equating social democrats with fascists, the policy isolated communists numerically—KPD membership peaked at around 360,000 in 1932 but electoral gains stalled without broader alliances—while fostering perceptions of communist intransigence among workers facing immediate threats.[1] Primary Comintern documents from 1928–1933 reveal no flexibility for ad hoc pacts, reinforcing the doctrine until the Seventh Congress reversal in 1935 amid fascist victories.Regional Variations Outside Europe
In China, the Comintern's Third Period doctrine translated into directives for the Chinese Communist Party (CCP) to prioritize urban proletarian uprisings and establish soviets, rejecting any collaboration with the Nationalist Kuomintang as "social fascist." This approach, influenced by Soviet advisors and figures like Pavel Mif, intensified after the CCP's Sixth Congress in June-July 1928, where Nikolai Bukharin advocated for aggressive class struggle amid perceived revolutionary opportunities. The policy fueled adventurist campaigns, such as Li Lisan's 1930 push for insurrections in Changsha and other cities, resulting in heavy casualties and territorial losses to Nationalist forces, with CCP membership plummeting from around 100,000 in 1930 to under 30,000 by 1933. Wang Ming's subsequent leadership, backed by Comintern funding and orthodoxy, extended this ultra-leftism, contributing to the encirclement and near-elimination of rural bases like Jiangxi Soviet by 1934, precipitating the Long March. In the United States, the Communist Party USA (CPUSA) implemented Third Period strategies by branding the American Federation of Labor (AFL) and its affiliates as instruments of "social fascism," thereby abandoning infiltration efforts in favor of creating parallel "revolutionary" unions under the Trade Union Unity League (TUUL), founded in September 1929. This shift emphasized dual unionism and direct action, as seen in strikes like the 1934 Minneapolis Teamsters' strike, where CPUSA influence promoted militant tactics but alienated broader workers, with party membership stagnating around 25,000-30,000 despite economic depression. The policy also manifested in cultural fronts, such as the John Reed Clubs, which prioritized ideological purity over mass appeal, leading to electoral isolation—CPUSA presidential votes fell from 1.06 million in 1928 (including write-ins) to under 100,000 by 1932. Across Latin America, Comintern agencies enforced Third Period sectarianism, directing local parties to denounce bourgeois nationalists and social democrats while organizing clandestine military cells for uprisings, often with disastrous results due to premature timing and isolation from indigenous peasant movements. In Brazil, the Aliança Nacional Libertadora (ANL), under Luís Carlos Prestes, attempted a nationwide revolt starting November 1935 in the northeast, seizing cities like Natal but collapsing within weeks amid government crackdowns, resulting in over 500 deaths and the execution or imprisonment of key leaders. Similar adventurism in Colombia's 1928-1931 strikes and Peru's underground activities reduced communist influence, with parties in countries like Chile and Argentina seeing membership dwindle as the policy's ultra-left rigidity clashed with regional semi-feudal dynamics and anti-imperialist sentiments. This phase's emphasis on proletarian exclusivity marginalized potential alliances, exacerbating organizational fragmentation until the 1935 Popular Front reversal.The Social Fascism Doctrine
Core Tenets and Comintern Promotion
The social fascism doctrine, formalized by the Communist International (Comintern), posited that social democracy represented "social-fascism," a conciliatory variant of fascism that stabilized capitalism through reformist policies, trade union bureaucracy, and bourgeois parliamentary illusions, thereby obstructing proletarian revolution.[8] Core to this view was the assertion that social democrats and fascists were ideological "twin brothers," with social democracy acting as the more pernicious force by dividing the working class and paving the way for open fascist terror during capitalism's terminal crisis.[8] The theory rejected any distinction between the two, directing communists to treat social democratic parties and their affiliated unions as the principal enemy, surpassing even avowed fascists, whom it depicted as a reactionary outburst signaling bourgeois desperation rather than a novel threat.[3] Comintern promotion began at the Sixth World Congress (July 1 to September 19, 1928), which proclaimed the Third Period of intensified revolutionary crisis and adopted program theses identifying social democracy as a counter-revolutionary bulwark akin to fascism.[3] The doctrine was sharpened and disseminated at the Tenth Plenum of the Comintern Executive Committee (July 1929), issuing resolutions that branded social democracy outright as "social-fascism" and mandated affiliated parties to prioritize anti-social democratic agitation, including dual unionism to siphon their membership and street-level confrontations over collaborative tactics.[8] Under Stalin's direction, enforcement involved purging non-compliant leaders, installing loyalists like Ernst Thälmann to head the German Communist Party, and propagating the line via Comintern journals and directives, framing it as essential for capturing the masses amid purported upsurges in class struggle.[8] This alignment served to synchronize global communist strategies with Soviet internal consolidation, marginalizing figures like Bukharin who had earlier toyed with similar rhetoric but resisted its extremes.[8]Application in Key Contexts
In Germany, the social fascism doctrine manifested most prominently through the Communist Party of Germany's (KPD) refusal to collaborate with the Social Democratic Party (SPD), prioritizing attacks on the latter as the "principal enemy" within the working class. KPD propaganda routinely equated SPD leaders with fascists, labeling figures like Otto Wels as "social fascists" and accusing the SPD of paving the way for capitalist dictatorship, as directed by Comintern resolutions from the Sixth Congress in 1928. This led to practical measures such as the establishment of rival "Red Aid" organizations to undermine SPD-linked welfare efforts and the promotion of independent KPD strikes that split worker unity, exemplified by opposition to SPD-led actions in Berlin's transport sector in 1932, where communists disrupted joint efforts against wage cuts.[8][27] A stark operational application occurred in the September 1931 Prussian Landtag referendum, where the KPD formed a temporary electoral pact with the Nazi Party (NSDAP) to dissolve the SPD-dominated state government, framing the SPD as the immediate "social fascist" threat more dangerous than overt fascism. This "red-brown" alliance secured over 5.6 million votes for dissolution but failed to topple the regime, highlighting the doctrine's tactical extremism; KPD leadership justified it as exposing social democratic "illusions" to workers, despite internal dissent from figures like Heinrich Brandler. In industrial contexts, the policy fueled dual unionism, with KPD-dominated factory cells boycotting SPD trade unions and inciting violence against their members, contributing to fragmented labor resistance amid rising unemployment, which reached 6 million by 1932.[20][8] In France, the French Communist Party (PCF) applied social fascism by denouncing the Socialist SFIO as a fascist variant complicit in colonial oppression and austerity, adhering to Comintern directives until external pressures shifted policy. PCF tactics included sabotaging SFIO-led strikes, such as during the 1931 metalworkers' disputes where communists formed breakaway committees to compete for influence, and rejecting joint anti-fascist demonstrations until riots in February 1934 prompted a tactical pivot. This period saw PCF membership dwindle to under 30,000 by 1932, as the doctrine alienated potential allies amid fascist leagues' growth, like the Croix-de-Feu numbering 500,000 by 1936.[28][27] Beyond Europe, the doctrine influenced ultra-left adventurism in China, where Comintern advisors like Pavel Mif directed the Communist Party to assault Kuomintang "social fascist" elements, culminating in the 1927 Shanghai massacre where urban insurrections were crushed, costing thousands of lives and forcing a rural pivot. In the United States, the Communist Party USA echoed the line by branding the Socialist Party as "social fascists" and disrupting their events, such as the 1932 Bonus Army march where CPUSA agitation alienated veterans, limiting recruitment despite the Great Depression's radicalizing effects. These applications underscored the Comintern's centralized imposition, often overriding local conditions for ideological purity.[29][27]Immediate Operational Consequences
The social fascism doctrine, formalized at the Sixth Comintern Congress in July–September 1928, directed affiliated parties to treat social democratic organizations as the primary enemy of the proletariat, superseding other bourgeois threats and mandating "class against class" confrontations. This shift enforced operational directives for independent communist actions, including the creation of parallel "red" mass organizations to siphon workers from social democratic unions and parties, such as the expansion of the Profintern's rival trade union networks which fragmented joint labor efforts across Europe.[30] In Germany, the KPD under Ernst Thälmann immediately amplified street-level hostilities against SPD paramilitaries like the Reichsbanner Schwarz-Rot-Gold, prioritizing clashes with "social fascists" over coordinated anti-capitalist mobilization, which isolated communists from broader working-class support.[24] Internally, parties underwent rapid purges of perceived "right opportunists" advocating any cooperation with social democrats, expelling thousands of members and leaders to align with the ultra-left line; for instance, the KPD ousted figures like Heinrich Brandler's remnants and enforced "Bolshevization" to centralize control under Moscow-vetted cadres, reducing tactical adaptability but intensifying militant rhetoric and adventurist initiatives like unauthorized factory occupations.[30] [31] Tactically, this manifested in "united front from below" strategies, urging communist agitation among social democratic rank-and-file while denouncing their leadership, but in operation it yielded limited conversions and heightened divisions, as evidenced by failed attempts to disrupt SPD-led strikes in Britain via the National Minority Movement, which alienated potential allies without building sustainable alternatives.[32] Electorally and organizationally, the doctrine spurred short-term polarization but immediate setbacks, with communist parties gaining marginal votes in contexts like the KPD's rise from 10.6% in the May 1928 German Reichstag election to 13.1% in September 1930 amid economic crisis, yet at the cost of refusing electoral pacts that could have consolidated anti-fascist opposition, thereby enabling right-wing advances through left disunity.[33] In France, the PCF's adherence led to schisms and membership drops from around 30,000 in 1928 to under 20,000 by 1930, as ultra-sectarian campaigns against the SFIO repelled moderate workers during rising unemployment.[34] These consequences underscored the doctrine's causal role in operational rigidity, prioritizing ideological purity over pragmatic mass engagement in the anticipated "third period" of capitalist collapse.[35]Consequences and Policy Reversal
Contribution to the Nazi Seizure of Power in Germany
The Communist Party of Germany (KPD), adhering to Comintern directives during the Third Period, designated the Social Democratic Party (SPD) as the primary enemy of the proletariat, branding it "social fascist" and prioritizing conflict with social democrats over opposition to the rising National Socialist German Workers' Party (NSDAP). This stance, formalized at the Comintern's Sixth World Congress in 1928, manifested in KPD propaganda and actions that equated SPD policies with fascism, such as claims that social democracy facilitated capitalist stabilization and worker betrayal.[36] Consequently, KPD members engaged in frequent street clashes with SPD-affiliated Reichsbanner Schwarz-Rot-Gold paramilitaries, diverting resources from unified anti-Nazi efforts amid the Great Depression's exacerbation of unemployment, which reached 6 million by 1932.[37] Electoral fragmentation underscored the policy's impact, as the divided left failed to consolidate working-class support against the Nazis' surge. In the May 1928 Reichstag election, the NSDAP secured 2.6% of the vote (810,127 votes, 12 seats), while the SPD held 29.8% (9,153,761 votes, 153 seats) and KPD 10.6% (3,264,857 votes, 54 seats); by September 1930, NSDAP support exploded to 18.3% (6,409,600 votes, 107 seats), with SPD at 24.5% (8,846,331 votes, 143 seats) and KPD at 13.1% (4,616,688 votes, 77 seats). The July 1932 election saw NSDAP peak at 37.3% (13,745,000 votes, 230 seats), narrowly ahead of combined SPD (21.6%, 7,952,000 votes, 133 seats) and KPD (14.3%, 5,280,000 votes, 89 seats) totals of 35.9%; even in November 1932, despite NSDAP decline to 33.1% (11,737,000 votes, 196 seats), left unity remained absent, with SPD at 20.4% (7,248,000 votes, 121 seats) and KPD at 16.9% (5,980,000 votes, 100 seats).[20]| Election Date | NSDAP % (Votes, Seats) | SPD % (Votes, Seats) | KPD % (Votes, Seats) |
|---|---|---|---|
| May 1928 | 2.6% (810,127, 12) | 29.8% (9,153,761, 153) | 10.6% (3,264,857, 54) |
| Sep 1930 | 18.3% (6,409,600, 107) | 24.5% (8,846,331, 143) | 13.1% (4,616,688, 77) |
| Jul 1932 | 37.3% (13,745,000, 230) | 21.6% (7,952,000, 133) | 14.3% (5,280,000, 89) |
| Nov 1932 | 33.1% (11,737,000, 196) | 20.4% (7,248,000, 121) | 16.9% (5,980,000, 100) |
