Liu Yu's Northern Expeditions (simplified Chinese: 刘裕北伐; traditional Chinese: 劉裕北伐; pinyin: Liú Yù Běi Fá) were a series of successful campaigns mounted by the Eastern Jin dynasty from 409 AD to 416 AD against the Southern Yan, Later Qin, Northern Wei and Hu Xia dynasties that successfully recovered all of Eastern Jin's territory south of the Yellow River with the exception of the Chang'an area, which was taken by Hu Xia. These victories were the basis of the prosperity of the Reign of Yuanjia.
