Lebanon's national legislature is the unicameral Parliament of Lebanon. Its 128 seats are divided equally between Christians and Muslims, proportionately between the 18 different denominations and proportionately between its 26 regions. Prior to 1990, the ratio stood at 6:5 in favor of Christians; however, the Taif Agreement, which put an end to the 1975–1990 civil war, adjusted the ratio to grant equal representation to followers of the two religions.
