Prince of Hongnong
In summer 907, Zhu Quanzhong forced Emperor Ai to yield the throne to him, ending the Tang Dynasty. He established a new Later Liang (as its Emperor Taizu). Most Tang military governors at least nominally submitted to him as emperor, with a few exceptions—Li Keyong, Yang Xingmi's son and successor Yang Wo (titled the Prince of Hongnong), Wang Jian (titled the Prince of Shu), and Li Maozhen (titled the Prince of Qi), all of whom initially continued to use the Tang era names to show refusal to submit to Later Liang. (Wang, however, soon declared himself emperor of a new state of Shu (commonly known as Former Shu)). In reality, Li Keyong's state of Jin was now an independent state, although when Wang wrote him and suggested that he assume imperial title as well, he refused, claiming continued loyalty to Tang. Later in the year, he met at Yun Prefecture (the one in Datong) with Yelü Abaoji, the ruler of the Khitan, and tried to enlist Yelü's aid in an alliance against Later Liang. Yelü initially agreed, but later entered into relations with Later Liang.
