Tang dynasty
Zhu Wen, originally a salt smuggler who had served under the rebel Huang Chao, surrendered to Tang forces. By helping to defeat Huang, he was granted a series of rapid military promotions. In 907 the Tang dynasty was ended when Zhu Wen, now a military governor, deposed the last emperor of Tang, Emperor Ai of Tang, and took the throne for himself (known posthumously as Emperor Taizu of Later Liang). He established the Later Liang, which inaugurated the Five Dynasties and Ten Kingdoms period. A year later Zhu Wen had the deposed Emperor Ai poisoned to death.

During Yang Pu's reign as emperor, she was honored as empress dowager.
