Tang dynasty
The Tang capital at Chang'an (present-day Xi'an) was then the world's most populous city. Two censuses of the 7th and 8th centuries estimated the empire's population at about 50 million people, which grew to an estimated 80 million by the dynasty's end. From its numerous subjects, the dynasty raised professional and conscripted armies of hundreds of thousands of troops to contend with nomadic powers for control of Inner Asia and the lucrative trade-routes along the Silk Road. Far-flung kingdoms and states paid tribute to the Tang court, while the Tang also indirectly controlled several regions through a protectorate system. The adoption of the title Khan of Heaven by the Tang emperor Taizong was eastern Asia's first "simultaneous kingship". In addition to its political hegemony, the Tang exerted a powerful cultural influence over neighboring East Asian nations such as Japan and Korea.

Tang dynasty [SEP] Introduction
The Tang dynasty (, ; ) or Tang Empire was an imperial dynasty ruling China from 618 to 907, with an interregnum between 690 and 705. It was preceded by the Sui dynasty and followed by the Five Dynasties and Ten Kingdoms period. Historians generally regard the Tang as a high point in Chinese civilization, and a golden age of cosmopolitan culture. Tang territory, acquired through the military campaigns of its early rulers, rivaled that of the Han dynasty. The Lǐ family () founded the dynasty, seizing power during the decline and collapse of the Sui Empire and inaugurating a period of progress and stability in the first half of the dynasty's rule.
