Republic of Lebanon
Who & why: Lebanon's parliament declared independence on 22 November 1943, still marked as its national day; the last French troops withdrew in December 1946. Governance since rests on the unwritten 1943 National Pact, a confessional power-sharing system distributing the country's top offices — the presidency, premiership, and speakership of parliament — among specific religious communities, a real and distinctive feature that remains in operation today. A civil war lasted from 1975 to 1990, formally ended by the 1989 Taif Agreement, which adjusted but did not abolish the confessional system.
