History
North Jeongmi was settled by Jeongmic peoples beginning in the 5th century BCE, who set up numerous independent polities that displaced the existing Fusenic and Resic peoples of the area. These polities engaged in constantly changing and diverse relations with Cheonje, ranging between paying tribute and raiding the areas of southern Jeogmi which had been formally incorporated into Cheonje.
