Year 90 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Caesar and Lupus (or, less frequently, year 664 Ab urbe condita) and the Third Year of Zhenghe. The denomination 90 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

  • The Xiongnu invade the Prefectures of Wuyuan and Jiuquan and kill the commandants of both Prefectures.
  • Emperor Wu of Han sends three armies against the Xiongnu under General-in-Chief Li Guangli, Ma Tong and Shang Qiucheng, marching from Wuyuan, Jiuqian and Xihe respectively. An army of Central Asian vassals of Han, under Cheng Mian, captures the king of the vassal state of Jushi, who is suspected of treachery. The Xiongnu General-in-Chief and the former Han general Li Ling fight indecisively against Shang's army.
  • Li Guangli and his in-law Prime Minister Liu Qumao seek to recommend Liu Bo, Li Guangli's nephew, as the new Crown Prince, and while Li Guangli is on campaign, Liu Qumao and his wife are executed and Li Guangli's wife imprisoned, having been charged with cursing the emperor and seeking to replace him with Liu Bo.
  • Wishing to please the emperor, Li Guangli and his 70,000 men penetrate as far as the Selenga River. A detachment crosses the river and defeats an army of 20,000 under the Xiongnu Left General-in-Chief, who is killed. However, Li Guangli is then defeated by Hulugu Chanyu's army of 50,000 in the Khangai Mountains and surrenders. Li Guangli marries Hulugu's daughter, and Emperor Wu exterminates Li's clan.[1]
