Fushun
Fushun was a fortified Ming settlement on the Hun River, guarding a route into the Jurchen lands east of Shenyang. It was also a place where the Ming traded with neighboring peoples. In 1618 Nurhaci attacked the city after declaring his grievances against the Ming. Its commander Li Yongfang surrendered, and the fall of Fushun marked the opening of a war that would overturn Ming rule in Liaodong. Li entered Later Jin service and married a granddaughter of Nurhaci.
