The Han conquest of Dian was a series of military campaigns and expeditions by the Western Han dynasty recorded in contemporary textual sources against the Dian Kingdom in modern-day Yunnan. Dian was placed under Western Han rule in 109 BC, after Emperor Wu of Han dispatched an army against the kingdom as the empire expanded southward.
