Mahan probably developed from the existing bronze society of third to second centuries BC, continuing to absorb migration from the north in subsequent centuries. King Jun of the kingdom of Gija Joseon in northern Korea, having lost the throne to Wiman, fled to the state of Jin in southern Korea around 194 - 180 BC. He and his followers are thought to have established a base within Jin territory. It is not certain whether Mahan conquered or arose out of this entity, but Mahan was certainly influenced by this influx of northern culture.
