On this day in 2000, the Israeli army withdrew from territory in Southern Lebanon, marking the end of the South Lebanon conflict (1985–2000). The withdrawal was largely because of the efforts of the Lebanese Army. It is celebrated as an important day in the history of Lebanon. The United Nations certified that the withdrawal was complete, with troops having left territory demarcated by the Blue Line. Lebanon disputed the completion of withdrawal, claiming that the Blue Line did not match with its international borders in a region between it and Syria called the Shebaa Farms.
