How Lebanon's Borders Were Drawn: The French Mandate Legacy

Lebanon's modern borders are a colonial construct—drawn by France in 1920 with minimal regard for sectarian demography.

The 1920 Act

• Date: 1 September 1920 — General Gouraud proclaims Grand Liban.
• Basis: Sykes-Picot (1916) + San Remo (1920) allocations. France wanted a Christian-majority client state on the Mediterranean.
• Lines drawn:
  • South: Litani River (approx.) — separated from British Palestine.
  • East: Anti-Lebanon Mountains — separated from Syrian interior.
  • North: Nahr al-Kabir River — separated from Turkish Syria (later Syria).
  • West: Mediterranean Sea.

Demographic Engineering

France added to the historic Mount Lebanon Mutasarrifate (Maronite/Druze core):

• Beirut & coast (Sunni, Greek Orthodox)
• Tripoli & Akkar (Sunni)
• Bekaa Valley (Sunni, Shia, Greek Catholic)
• South Lebanon (Shia majority)

Result: Maronites dropped from ~80% to ~30% — creating a sectarian balance requiring power-sharing (National Pact 1943, Taif 1989).

Enduring Disputes

• Israel: Shebaa Farms / Ghajar (occupied 1978–2000; UN says Syrian; Lebanon claims).
• Syria: Border never fully demarcated; 2022 talks stalled.
• Palestinian refugees: 12 camps, 480k UNRWA-registered — no citizenship, limited rights.

Lebanon's borders were imposed from outside for imperial convenience. The resulting pluralism fuels both its cultural richness and its chronic instability.
