Wu Zhou

Historical Development

In the later reign of Emperor Gaozong of Tang, Wu Zetian gradually participated in and then dominated government. After Gaozong died in 683, she ruled as empress dowager and successively deposed and enthroned Emperor Zhongzong and Emperor Ruizong. In 690, the first year of Tianshou, Wu Zetian accepted petitions urging her to take the throne, changed the state name to Zhou, and proclaimed herself emperor. She governed from Luoyang, promoted officials who entered central government through the imperial examinations and special examinations, and also used cruel officials to strike at opponents. In the middle and later period of the regime, competition arose between the Wu clan and the Li-Tang imperial family over succession. In 705, the first year of Shenlong, Zhang Jianzhi and others launched a coup, Wu Zetian abdicated, and Li Xian was restored.

Politics and Institutions

Wu Zhou largely retained Tang's Three Departments and Six Ministries, prefectural and county administration, and examination system, while repeatedly changing the names of government offices to create symbols of the new regime. Wu Zetian expanded recruitment through the imperial examinations and special examinations, promoting officials such as Di Renjie and Yao Chong and weakening the monopoly of older Guanzhong-Longxi aristocratic families. The use of cruel officials and denunciation systems suppressed opponents but also created political fear. In her later years, favored courtiers and succession disputes intensified court conflict.

Military and Diplomacy

Wu Zhou faced pressure from the Turks, Tibetans, Khitans, and other powers in the Western Regions, the north, and the northeast. The Four Garrisons of Anxi were restored for a time, and frontier garrisons continued to bear the burden of imperial defense. The Khitan uprising of 696 exposed weaknesses in Hebei's defenses. External war and domestic politics developed simultaneously, and the appointment of military commanders became important to imperial stability.

Economy and Commerce

Wu Zhou inherited Tang's early equal-field system, rent-labor-tax arrangements, and prefectural fiscal system, while agriculture and population continued to grow overall. Luoyang received major investment as the Divine Capital and was connected to Guanzhong, Hebei, and Jianghuai through grain-transport routes. Policies emphasized agriculture and local administration, although major construction projects, frontier wars, and court expenses also increased fiscal burdens.

Culture and Society

Wu Zetian used ritual institutions, auspicious omens, Buddhist scriptural interpretations, and monumental religious imagery to justify female rulership. Surviving sites such as the Longmen Grottoes reflect the combination of state power, religion, and art. Expansion of the examination system promoted literary culture and bureaucratic mobility. Assessment of Wu Zhou should consider both political propaganda and changes in recruitment channels and social structure.

Rulers and Political Core

Wu Zetian; Li Xian and Li Dan were central to the succession and restoration processes before and after the change of state name.

Historical Assessment and Legacy

Wu Zhou altered the structure of imperial succession and the political elite during the Tang period, expanded examination recruitment, and strengthened Luoyang's political position. Traditional histories often criticized female imperial rule and the politics of cruel officials, while modern scholarship has paid greater attention to institutional continuity, political mobilization, and gender. Treating Wu Zhou as a separate entity helps explain the fifteen-year change of state name, but its institutional continuity with Tang must be emphasized.
