Cause

Israel invaded Lebanon in 1978 and 1982 to suppress Palestinian insurgency and support Maronite Christians in the Lebanese Civil War. The 1982 invasion drove out the PLO but triggered a new threat: militant Shia groups, most notably Hezbollah, began attacking Israeli forces in September 1982, prompting Israel to establish a self-declared 'security zone' along its northern border by 1985.

Event

From 1985 to 2000, Israel and its proxy the South Lebanon Army held a border 'security zone' against Hezbollah and allied guerrillas backed by Iran and Syria. Hezbollah waged sustained guerrilla and psychological warfare, launching rockets into Galilee and eroding Israeli public support. Israel launched major operations in 1993 and 1996, but neither resolved the conflict. The Four Mothers movement shaped domestic opinion against continued occupation.

Consequence

Mounting casualties and domestic pressure led Prime Minister Ehud Barak to unilaterally withdraw all Israeli forces on 25 May 2000, causing the immediate collapse of the SLA. Many SLA members fled to Israel. Hezbollah claimed victory and expanded its political influence in Lebanon, while the Shebaa Farms dispute left the withdrawal contested and a residual source of tension between Israel, Lebanon, and Hezbollah.
