After the rebellion of the Trưng Sisters, more direct rule and greater efforts at sinicization were imposed by the Han dynasty. The territories of the Lạc lords were revoked and ruled directly, along with other former Yue territories to the north, as provinces of the Han empire. Division among the Yue leaders were exploited by the Han dynasty with the Han military winning battles against the southern kingdoms and commandaries that were of geographic and strategic value to them. Han foreign policy also took advantage of the political turmoil among rival Yue leaders and enticed them with bribes and lured prospects for submitting to the Han Empire as a subordinate vassal.
