Jurchens broke out in warfare with the Ming in Liaodong in which Nurhaci fought with Xiong Tingbi (1569-1625), the Ming military commander. By this time, he had declared a unified Jurchen regime that called itself "Jin," reminiscent of the former Jurchen empire. From this warfare, the Ming grew increasingly aware of Nurhaci's increasing and tremendous military power. Nurhaci, in 1622, convinced Mongols who were supporting the Ming's military efforts, to abandon their posts and it resulted in a disastrous defeat for the Ming at Guangning. Nurhaci's troops soon occupied Shenyang, the former Ming provincial capitol. This battle helped strengthen the Jianzhou and established more relationships with surrounding groups.
