Han Chinese commoners started pledging their allegiance as buqu (部曲) (armed retainers) to elite Han Chinese aristocratic magnates in their wubao (塢堡) (fortified settlements) when the local communities relied on the magnates to direct their defense after the 311 sack of Luoyang. Oaths were pledged in alliances between paramount commanders who joined their fortress villages together in leagues. The magnates retained the services and fealty of their thrall retainers after the fighting was over. Subject to the emperor was overtaken by the concept of village membership. Magnates had both unrelated bondsmen, private clients and fellow clan kinsmen in their armies. 50 to 60 square leagues of farmland in Hebei's southwest Taihang mountain foothills were taken as a fief by thousands of members of the Han Chinese aristocratic Zhaojun Li clan under the leader of a cadet leader of the clan, Li Xianfu. Clan loyalties were extensively utilized by local magnates. Li Xianfu was appointed as zongzhu (宗主) (clan chief) by the clan collectively in spite of him not inheriting the officer and rank of his father which went to his elder brother. Local level order was controlled by Li Xiangu and other magnates and the Northern Wei Xianbei monarchs had to rely on them. The Northern Wei gave them title of governors officially in their fiefs.
