Kings of the Han dynasty
The kings from other dynasties (, "yìxìng wáng") were mostly remnants of the rebellion against the Qin dynasty. Following the Dazexiang Uprising, many noblemen rose in rebellion. Heirs, pretenders, and warlords called themselves "kings" and claimed sovereignty as continuations of the six states previously suppressed by Qin. Among these, Chu was the most powerful. However, its rightful ruler Huai II was assassinated on the orders of the warlord Xiang Yu and the 18 Kingdoms Xiang had formed rose in rebellion against him. Liu Bang, king of Han, ultimately defeated Chu and established the new Han dynasty. The kings who had sided with him were then permitted to maintain their titles and lands. A few other kingdoms were also formed by Liu Bang for generals and favorites.

Empress Dowager Wang (王太后, personal name unknown) was briefly an empress dowager of the Chinese dynasty Liang Dynasty. She was the wife of Xiao Huan (蕭歡), Prince An of Yuzhang, a grandson of the dynasty's founder Emperor Wu through his first crown prince, Xiao Tong. Her son Xiao Dong the Prince of Yuzhang was made the emperor in 551 by the general Hou Jing, who had taken over the imperial government, to replace his granduncle Emperor Jianwen.
