The Tang Empire
The Tang dynasty reunited continental East Asia using institutions inherited from the nomad-dominated Northern dynasties: state-owned land; exactions of grain, cloth, and labor service levied on notional “average” households; a hereditary “divisional army” concentrated around the capital and professional soldiers at the frontier, cities divided into walled wards with state-administered markets; a hereditary, imperial super-elite; and state-sponsored Buddhism and Daoism. The An Lushan Rebellion in the mid-eighth century eliminated these institutions. In their place emerged the major characteristics of late-imperial China: a fiscal system that assessed actual wealth and taxed trade; a new pattern of state service based on textual, technical, and military expertise measured by examinations; large-scale interregional trade through purely commercial entrepôts and local market towns; the incorporation of China into a multistate East Asian world; and the linkage of continental East Asia into a world economy through oceanic trans-shipment of commodities.
