The Tang dynasty, with its capital at Chang'an, the most populous city in the world at the time, is regarded by historians as a high point in Chinese civilization-- equal, or even superior, to the Han period. Its territory, acquired through the military exploits of its early rulers, was greater than that of the Han. Stimulated by contact with India and the Middle East, the empire saw a flowering of creativity in many fields. Buddhism, originating in India around the time of Confucius, continued to flourish during the Tang period and was adopted by the imperial family, becoming thoroughly sinicized and a permanent part of Chinese traditional culture. Block printing made the written word available to vastly greater audiences.
The Tang period was the golden age of literature and art. A government system supported by a large class of Confucian literati selected through civil service examinations was perfected under Tang rule. This competitive procedure was designed to draw the best talents into government. But perhaps an even greater consideration for the Tang rulers, aware that imperial dependence on powerful aristocratic families and warlords would have destabilizing consequences, was to create a body of career officials having no autonomous territorial or functional power base. As it turned out, these scholar-officials acquired status in their local communities, family ties, and shared values that connected them to the imperial court. From Tang times until the closing days of the Qing empire in 1911, scholar officials functioned often as intermediaries between the grassroots level and the government.
By the middle of the 8th century, Tang power had ebbed. Military defeat in 751 by Arabs at the Battle of Talas marked end of Tang authority in Central Asia. Domestic economic instability and subsequent rebellions of An Lushan and warlordism marked the beginning of five centuries of steady military decline for the Tang empire. Misrule, court intrigues, economic exploitation, and popular rebellions weakened the empire, making it possible for warlord Zhu Wen to terminate the dynasty in 907. The next half-century saw the fragmentation of China into five northern dynasties and ten southern kingdoms.
