Zhènxióng

Zhenxiong originated as Mangbu, a Wuman Yi domain in the mountains where Yunnan, Sichuan and Guizhou meet. The Yuan established Mangbu Route in 1285; the hereditary Long clan later ruled its Ming successor.

In 1525 Long Zheng lured his half-brother and recognized heir Long Shou to his death and seized the seal. Ming forces intervened in 1526, replacing native rule and renaming it Zhenxiong Military and Civilian Prefecture; it became the regular Zhenxiong Prefecture in 1609. The Qing transferred it to Yunnan in 1727, then reduced it to a department after the Wumeng rising of 1728.
