The Palestinian insurgency in South Lebanon was a conflict initiated by Palestinian militants based in South Lebanon upon Israel since 1968, which evolved into the wider Lebanese Civil War in 1975 and lasted until the expulsion of the Palestinian Liberation Organization from Lebanon in the 1982 Lebanon War. Though the PFLP and some other Palestinian factions continued a low-level military activities against Israel from Lebanese soil, after 1982, the conflict is considered to have shifted from Palestinian-Israeli to Israel-Hezbollah conflict. The South Lebanon insurgency, which peaked through the 1970s, claimed hundreds of Israeli and Palestinian military and civilian lives, and is considered among the key elements to starting the Lebanese Civil War.
