赵桓子 / Zhao Huanzi

赵桓子 / Zhao Huanzi appears in 《资治通鉴·周纪》04｜豫让 为智瑶复仇 as 赵襄子’s younger brother Zhao Jia. After Zhao Xiangzi dies in 425 BCE, Zhao Huanzi drives out 赵浣 / 赵献子 and briefly becomes Zhao clan leader.

The source says Zhao Huanzi dies in 424 BCE. Zhao clan leaders then respect Zhao Xiangzi’s earlier designation, kill Zhao Huanzi’s son, and restore Zhao Xianzi from exile. This makes Zhao Huanzi the usurpation figure in the episode’s succession branch.
