The Blue Line is a United Nations–identified withdrawal line — not an international border — used to verify Israel’s withdrawal from southern Lebanon under UN Security Council resolutions.
Location and extent:
It runs along southern Lebanon, adjoining northern Israel, stretching about 120 km from the Mediterranean Sea to the tri-border area near the Golan Heights. It touches Lebanon, Israel, and the Israeli-occupied Golan Heights (bordering Syria).
Origin:
The Blue Line was established in 2000 by the UN to confirm Israel’s compliance with UNSC Resolution 425 (1978) following its withdrawal from Lebanon.
APSC relevance: International borders vs withdrawal lines, West Asia geopolitics, UN peacekeeping and conflict-mitigation tools.
