陈桥兵变 / Chenqiao Mutiny
Chenqiao Mutiny / 陈桥兵变 is the founding coup of the 北宋 in 169.宋太祖之死：烛影斧声，阴谋论中的人性谜团（上）. The episode describes a reported northern border emergency, 赵匡胤 leading troops out from 开封, omen talk around two suns, soldiers demanding a new ruler, and the famous 黄袍加身 scene.
The source treats the event as staged or at least heavily prepared. 石守信’s control of the capital gate, the ready abdication text, and the immediate pressure on Later Zhou ministers make “being forced by the army” look like a necessary political script rather than a full explanation.
Chenqiao also becomes the root problem that 宋初军事集权 tries to solve. Zhao Kuangyin gained power through military command; after gaining it, he had to prevent other commanders from repeating the same move.
