The Han campaigns against Minyue were a series of three Han military campaigns dispatched against the Minyue state. The first campaign was in response to Minyue's invasion of Eastern Ou in 138 BCE. In 135 BCE, a second campaign was sent to intervene in a war between Minyue and Nanyue. After the campaign, Minyue was partitioned into Minyue, ruled by a Han proxy king, and Dongyue. Dongyue was defeated in a third military campaign in 111 BCE and the former Minyue territory was annexed by the Han Empire.
