Lebanon

Lebanon has one of the Middle East's most religiously diverse populations, with no official census since 1932 for fear of upsetting its delicate sectarian balance, though estimates commonly place the population at roughly 60 to 65 percent Muslim, divided closely between Sunni and Shia, and around 30 to 35 percent Christian, chiefly Maronite Catholic alongside Greek Orthodox, Greek Catholic and smaller denominations, with a small Druze minority. Mount Lebanon served historically as a refuge for religious minorities fleeing persecution elsewhere, allowing the Maronite Church, in communion with Rome since at least the twelfth-century Crusader period while retaining its own Syriac liturgical heritage, and the Druze, an esoteric offshoot of Ismaili Islam, to establish durable mountain strongholds under Ottoman-era autonomy.

Beirut and the coastal cities held significant Sunni Muslim populations tied to broader Mediterranean and Levantine trade networks, while Shia Muslim communities concentrated historically in the south and the Bekaa Valley. French colonial administration after the First World War, exercising a mandate that favored Christian, particularly Maronite, political interests, shaped the modern state's 1943 National Pact power-sharing formula at independence.

Lebanon's political system rests on confessionalism, an arrangement fixing the presidency for a Maronite Christian, the premiership for a Sunni Muslim and the parliamentary speakership for a Shia Muslim under the 1943 National Pact, later adjusted by the 1989 Taif Agreement that ended the 1975 to 1990 civil war and rebalanced legislative seats more evenly between Christians and Muslims.

The civil war itself was fought substantially along sectarian lines, drawing in Palestinian, Syrian and Israeli forces at various points, and produced lasting demographic shifts as many Christians emigrated, gradually eroding the Christian majority the system had originally been designed around; Shia political and demographic weight has grown significantly since, embodied politically by Hezbollah, an Iranian-backed Shia Islamist party and militia that emerged during the war and has become the country's most powerful armed actor, drawing sustained conflict with Israel including major wars in 2006 and again in 2024. Reform advocates have long argued that confessionalism entrenches sectarian elites and blocks effective governance, a critique that intensified after the catastrophic 2020 Beirut port explosion exposed the system's chronic dysfunction, though no confessional formula has yet been replaced.
