Emperor Wu of Han

Emperor Wu of Han (30 June 156 BC – 29 March 87 BC), born Liu Che, courtesy name Tong, was the seventh emperor of the Han dynasty of China, ruling from 141–87 BC.

Emperor Wu's reign lasted 54 years — a record that was not broken until the reign of the Kangxi Emperor more than 1,800 years later, although he has remained the longest reigning Emperor of Han ethnicity. His reign resulted in vast territorial expansion, development of a strong and centralized state resulting from his governmental re-organization, including his promotion of Confucian doctrines. In the field of historical social and cultural studies, Emperor Wu is known for his religious innovations and patronage of the poetic and musical arts, including development of the imperial Music Bureau into a prestigious entity. It was also during his reign that cultural contact with western Eurasia was greatly increased, directly or indirectly. Many new crops and other items were introduced to China during his reign.

As a military campaigner, Emperor Wu led Han China through its greatest expansion — at its height, the Empire's borders spanned from modern Kyrgyzstan in the west, to Korea in the east, and to northern Vietnam in the south. Emperor Wu successfully repelled the nomadic Xiongnu from systematically raiding northern China, and dispatched his envoy Zhang Qian in 139 BC to seek an alliance with the Yuezhi of modern Uzbekistan. This resulted in further missions to Central Asia. Although historical records do not describe him to be aware of Buddhism, emphasizing rather his interest in shamanism, the cultural exchanges that occurred as a consequence of these embassies suggest that he received Buddhist statues from Central Asia, as depicted in the murals found in the Mogao Caves.
