晋静公 / Duke Jing of Jin
晋静公 / Duke Jing of Jin appears in Zhouji 09 first as 晋孝公’s son and successor. The source then says 韩国, 赵国, and 魏国 depose him, reduce him to commoner status, and divide the last remnant of 晋国.
His source role is terminal. Jin Jing Gong marks the point where the old Jin polity stops being a residual title behind the three successor states and becomes a completed historical extinction in the episode’s account.
