After The Death Of Emperor Gongsun Shu Of Chengjia The Empire Was Conquered By The Eastern Han Dynasty - December 25 in History

AD 36 (XXXVI) was a leap year starting on Sunday of the Julian calendar. At the time, it was known as the Year of the Consulship of Allenius and Plautius. The denomination AD 36 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Gongsun Shu was the founder and only emperor of Chengjia, a state that controlled China's Sichuan Basin from 25 to 36. A successful official of the Western Han and short-lived Xin dynasties, Gongsun was the Administrator of Daojiang Commandery when the Xin regime fell in 23, amid rebellions aimed at restoring the Han dynasty. Through a series of political and military maneuvers, Gongsun secured control of Yi Province and in 24 proclaimed himself king of Shu. In the following year, he assumed imperial title and founded the Cheng dynasty. Under his administration, the Sichuan region experienced a period of peace and economic prosperity, and the city of Chengdu was developed into an imperial capital. But Gongsun adopted a defensive military posture that kept his influence confined within Sichuan while Liu Xiu's revived Eastern Han regime secured the North China Plain. In 36, Gongsun was mortally wounded in battle against an Eastern Han invasion force, and Chengjia capitulated on the following day.

Chengjia, also called the Cheng dynasty or Great Cheng, was a self-proclaimed empire established by Gongsun Shu in 25 AD after the collapse of the Xin dynasty of Chinese history, rivalling the Eastern Han dynasty founded by Emperor Guangwu later in the same year. Based in the Sichuan Basin with its capital at Chengdu, Chengjia covered a large area including modern Sichuan, Chongqing, Guizhou, Yunnan, and southern Shaanxi, and comprised about 7% of China's population at the time. Chengjia was the most dangerous rival to the Eastern Han and was the last separatist regime in China to be conquered by the latter, in 36 AD.

The Han dynasty was an imperial dynasty of China established by Liu Bang and ruled by the House of Liu. The dynasty was preceded by the short-lived Qin dynasty (221–206 BC) and a warring interregnum known as the Chu–Han Contention (206–202 BC), and it was succeeded by the Three Kingdoms period (220–280 AD). The dynasty was briefly interrupted by the Xin dynasty (9–23 AD) established by the usurping regent Wang Mang, and is thus separated into two periods—the Western Han and the Eastern Han (25–220 AD). Spanning over four centuries, the Han dynasty is considered a golden age in Chinese history, and had a permanent impact on Chinese identity in later periods. The majority ethnic group of modern China refer to themselves as the "Han people" or "Han Chinese". The spoken Chinese and written Chinese are referred to respectively as the "Han language" and "Han characters".

After the death of Emperor Gongsun Shu of Chengjia, the empire was conquered by the Eastern Han dynasty.
