The Yemeni Civil War was a civil war fought between the two Yemeni forces of the pro-union northern and the socialist separatist southern Yemeni states and their supporters. The war resulted in the defeat of the southern armed forces, the reunification of Yemen, and the flight into exile of many Yemeni Socialist Party (YSP) leaders and other separatists.
