檀石槐 / Tanshihuai (Xianbei)
檀石槐 / Tanshihuai enters the wiki through Hanji 920 as the earlier 鲜卑 leader whose death sets up a weaker succession branch. The source transcript renders him as “谭世桓”; this page normalizes the name to Tanshihuai because the sequence of his son 和连 and nephew-line successor 魁头 matches the late-Han Xianbei leadership transition.
The source uses Tanshihuai mainly by contrast. After his death, Xianbei still invades 幽州 and 并州, but He Lian is presented as less capable and morally weaker, so frontier pressure is paired with steppe-side succession fragility rather than simple continuity.
