Confessional Power-Sharing and Its Breakdown

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.
