宋悼公 / Duke Dao of Song

宋悼公 / Duke Dao of Song appears in 《资治通鉴·周纪》07丨两起刺杀（2） through a 396 BCE succession notice. The episode says he dies and his son 宋休公 succeeds him.

The source uses the notice mostly as an entry into 宋国’s special status as a Shang-remnant state, rather than as a detailed biography of Duke Dao.
