Wu Zetian
Wu Zetian (624–705 CE), born Wu Zhao, was the only woman to rule as emperor of China in her own right, founding the short-lived Second Zhou dynasty from 690 to 705 as an interregnum within the [Tang dynasty](/page/Tang dynasty).[1][2] She originated from a merchant family in Wenshui County, Shanxi Province, entering the imperial court as a low-ranking concubine to Emperor Taizong in 637, later becoming a favored consort to his successor, Emperor Gaozong, whom she married after Taizong's death.[3][1] As empress consort from 655, Wu Zetian exerted substantial influence over Gaozong's decisions amid his health issues, deposing rivals and consolidating power through strategic alliances and informants.[4] Following Gaozong's death in 683, she ruled as regent for her sons Emperors Zhongzong and Ruizong, ultimately deposing them in 690 to proclaim herself emperor, adopting the reign name Zetian and relocating the capital to Luoyang.[1][3] Her administration prioritized meritocratic selection of officials via expanded examinations, land redistribution to bolster agriculture, and suppression of aristocratic privileges, fostering economic growth and military campaigns that expanded Tang borders into Central Asia.[1][5] She prominently sponsored Buddhism, commissioning temples and scriptures to legitimize her rule, including self-identifying with the Maitreya Buddha.[6] Wu Zetian's reign, however, involved ruthless purges of Confucian officials and Li family members perceived as threats, employing secret police and executions that numbered in the thousands, actions later amplified in historical records by Tang loyalists to vilify her usurpation.[2][4] Forced to abdicate in 705 amid a coup by her ministers, she died later that year, with her legacy enduring as a symbol of female political agency amid enduring debates over her methods' necessity for dynastic stability.[1][2]Names and Titles
Personal Names and Origins
Wu Zetian's birth name was Wu Zhao (武曌), though some historical records alternatively record it as Wu Mei (武媚), reflecting the rarity with which women's given names were documented in Tang-era sources.[7][8] The surname Wu traced to her family's origins in Wenshui County, Bingzhou prefecture (modern Taiyuan, Shanxi province), where the clan had risen from timber merchant roots; her father, Wu Shihuo, leveraged commercial success into official appointments, leading to her birth in 624 CE at Lizhou (modern Guangyuan, Sichuan province, then part of Guang Prefecture) during one such posting.[1][7] This discrepancy between ancestral seat and birthplace underscores reliance on Tang dynastic histories like the Old Book of Tang, which prioritize clan genealogy over precise nativity amid mobile bureaucratic families.[1] Upon ascending power, Wu adopted a unique iteration of her given name by inventing the character 曌 (zhào) for Zhao, combining radicals for "sun" (日), "moon" (月), and "to illuminate" or "cloud" to evoke celestial brilliance and dual luminosity under heaven's canopy, symbolizing transcendent authority beyond conventional naming.[8][9] This neologism avoided homophonous common characters, aligning with her broader efforts to craft nomenclature evoking Buddhist-influenced cosmic harmony, though direct etymological ties to specific sutras remain interpretive rather than explicit in primary records.[1] Her temple name, Zetian (則天), connoted "ruling in accordance with heaven," a posthumous designation emphasizing Mandate of Heaven legitimacy, while her full posthumous title became Zetian Dasheng Huangdi (則天大聖皇帝), or "Emperor Zetian the Great and Sagacious."[9] To bolster imperial claims, Wu eschewed "empress" (huánghòu) in self-reference, instead employing huangdi (皇帝, "emperor") to equate her sovereignty with male precedents, circumventing Confucian gender norms and affirming dynastic rupture via the Zhou interregnum.[10][1]Imperial and Posthumous Titles
Wu Zetian's formal titles progressed from those denoting subordinate imperial roles to assertions of supreme sovereignty, marking her unprecedented status as China's sole female emperor. During her service under Emperor Taizong (r. 626–649), she received the title zhaoyi (昭仪), a rank within the concubine hierarchy that signified favor but subordinate position to the empress and higher consorts.[11] Following Taizong's death and her marriage to Emperor Gaozong (r. 649–683), she ascended to huanghou (皇后, empress consort) on October 17, 655, after the deposition of Empress Wang, consolidating her influence within the Tang court.[1] By 660, she adopted the elevated title Tianhou (天后, Heavenly Empress), reflecting growing authority during Gaozong's reign, though still framed within consort norms.[8] In a deliberate break from tradition, Wu Zetian proclaimed herself huangdi (皇帝, emperor) on October 16, 690, founding the Wu Zhou dynasty and changing the imperial surname from Li to Wu; this title, rendered as Zetian Dasheng Huangdi (則天大聖皇帝, Emperor Who Regulates Heaven, Great and Sagely), rejected the diminutive "hou" suffix to equate her rule with that of male predecessors, thereby legitimizing female sovereignty amid Confucian patriarchal constraints.[9][8] The dynasty name Wu Zhou, coupled with era titles like Tianshou (天授, Heaven-bestowed, 690–692), invoked celestial authority to embed ideological claims of divine endorsement, diverging from Tang naming conventions tied to ancestral Li lineage.[3]| Period | Key Title | Significance |
