Quizplus · Accepted Answer

The Xiongnu were a confederation of nomadic peoples who lived north of China and posed a significant military threat to the Han dynasty during the 3rd century BC to the 1st century AD. They were skilled horsemen and archers and carried out frequent raids and border skirmishes with the Han. The Han dynasty established treaties and paid tributes to the Xiongnu to maintain peace and stability along the northern territories. In 120 BC, Han Wudi initiated a military campaign against the Xiongnu, which lasted for several decades and resulted in the weakening of the Xiongnu confederation.
