The 1997 Israeli helicopter disaster occurred on February 4, 1997, when two Israeli Air Force transport helicopters ferrying Israeli soldiers into Israel's security zone in southern Lebanon collided in mid-air, killing all 73 Israeli military personnel on board. The crash brought about widespread national mourning and is considered a leading factor in Israel's decision to withdraw from southern Lebanon in 2000.

The South Lebanon conflict, designated by Israel as the Security Zone in Lebanon Campaign, was a protracted armed conflict that took place in southern Lebanon from 1985 to 2000. It saw fighting between Israel and the Catholic Christian-dominated South Lebanon Army (SLA) against Hezbollah-led Shia Muslim and left-wing guerrillas within the Israeli-occupied "Security Zone"; the SLA had military and logistical support from the Israel Defense Forces over the course of the conflict and operated under the jurisdiction of the Israeli-backed South Lebanon provisional administration, which succeeded the earlier Israeli-backed State of Free Lebanon. It can also refer to the continuation of the earlier conflict in this region involving the growing Palestinian insurgency in South Lebanon against Israel following the expulsion of the Palestine Liberation Organization (PLO) from Jordan after Black September. Historical tensions between Palestinian refugees and Lebanese factions contributed another layer to the Lebanese Civil War (1975–1990), which saw the Maronite-led Lebanese Front and the Shia Amal Movement at war with the PLO. Hence, the South Lebanon conflict can partly be seen as an extension of the civil war that ended in 1990.
