Zhang Zuo
In 353, Zhang Chonghua died, and Zhang Yaoling became the ruler (as Duke Ai), but actual power was in the hands of Zhang Chonghua's older brother Zhang Zuo, who was having an affair with Zhang Chonghua's mother Princess Dowager Ma and received her support in early 354 to depose Zhang Yaoling and claim the throne himself. Later that year, when he declared independence from Jin Dynasty (266–420), which Former Liang had been a titular vassal of, he created Zhang Xuanjing the Marquess of Liangwu.
