The Han–Xiongnu War, also known as the Sino-Xiongnu War and the Han-Hun War was a series of military battles fought between the Chinese Han dynasty and the Xiongnu confederated state from 133 BC to 89 AD. Under Emperor Wu's reign (r. 141–87 BC), the Han empire changed from a relatively passive foreign policy to an offensive strategy both in order to deal with the increasing Xiongnu incursions on the northern frontier and also according to general imperial policy to expand the domain. In 133 BC, the conflict escalated to a full-scale war when the Xiongnu realized that the Han was about to ambush them at Mayi. The Han court decided to deploy several military expeditions towards the regions situated in the Ordos Loop, Hexi Corridor, and Gobi Desert in a successful attempt to conquer it and expel the Xiongnu.
Hereafter, the war progressed further towards the many smaller states of the Western Regions. The nature of the battles varied through time with many casualties during the changes of possession or loss of actual control over the western states near the frontier regions. Regional alliances also tended to shift or get broken forcibly depending on the situation as one party gained the upper hand in a certain territory over the other. The Han empire's political influence expanded deeply into Central Asia. As the situation deteriorated for the Xiongnu, civil war befell and weakened the confederation. Eventually, the Southern Xiongnu submitted to the Han empire while the Northern Xiongnu continued to resist. Marked by significant events involving the conquests over various smaller states for control and many large-scale battles, the war resulted in the total victory of the Han empire over the Xiongnu state in 89 AD.
During the Warring States period, the Qin, Zhao, and Yan states conquered various nomadic territories inhabited by the Xiongnu and other Hu peoples. They strengthen their new frontiers with elongated wall fortifications. By 221 BC, the Qin ended the chaotic Eastern Zhou period by conquering all other states and unifying the entire nation. In 215 BC, Qin Shi Huang ordered General Meng Tian to set out against the Xiongnu tribes, situated in the Ordos region, and establish a frontier region at the Ordos Loop. Believing that the Xiongnu were a possible threat, the emperor launched a pre-emptive strike against the Xiongnu with the intention to expand his empire. Later that year (215 BC), General Meng Tian succeeded in defeating the Xiongnu and driving them from the Ordos region, seizing their territory as result. After the catastrophic defeat at the hands of Meng, Touman Chanyu and his followers fled far into the Mongolian Plateau.Fusu (Prince of Qin) and General Meng Tian were stationed at a garrison in Suide and soon began with the construction of the walled defenses, connecting it with the old walls built by Qin, Yan and Zhao states. The fortified walls ran from Liaodong to Lintao, thus enclosing the conquered Ordos region, safeguarding the Qin empire against the Xiongnu and other northern nomadic people. Due to the northward expansion, the threat that the Qin empire posed to the Xiongnu ultimately led to the state formation of the many tribes towards a confederacy.
