Yingjiang, China

History

Yingjiang county became part of Chinese territory for the first time in the Western Han dynasty. It was under control of Yizhou Prefecture (益州郡) (Yìzhōu jùn) in the Western Han dynasty. During the Eastern Han, the Shu Han, the Western Jin, and the Eastern Jin, it was governed by Ailao county (哀牢縣) (Āiláo xiàn), Yongchang Prefecture (永昌郡) (Yǒngchāng jùn), and then by Xicheng county (西城縣) (Xīchéng xiàn) from the Southern Qi dynasty in 479.

From the 320s, the Cuan (爨) (Cuàn) family began to control Yunnan. China was very unstable during the Northern and Southern Dynasties, and the central governments had no force to control Yunnan. The Cuan family took the strategy by which they recognized the nominal sovereignty of the central governments while remaining themselves as the real local rulers. In this way, the Cuan family had controlled Yunnan for more than 400 years until it was conquered by Nanzhao in 769.

Yingjiang was ruled by Nanzhao and later by Dali from the 8th to the 13th century and hence was not governed by China during the Tang dynasty and the Song dynasty. It was conquered by the Mongols and again became part of the Chinese territory. During the Ming dynasty and the Qing dynasty, Yingjiang was governed by local chiefs under the "Tusi system" (土司制度) (Tǔsī Zhìdù), i.e. the Native Chieftain system, in which the central government had the nominal sovereignty.
