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.
What it represents: two red horizontal bands framing a wider white band bearing a green cedar tree (Cedrus libani), set in the Constitution on 7 December 1943 at independence; the layout is unchanged since, but Wikipedia says the cedar was usually drawn with a brown trunk until a 1990 amendment made the whole tree green, while Flags of the World says it was officially green from the start.
Wikipedia: the flag was introduced into the Constitution on 7 December 1943 (first raised 21 November 1943 at Bechamoun), three horizontal stripes with a double-width white stripe and a cedar occupying one third of it. Flags of the World: adopted 07 Dec 1943; the 1926 constitution's blue-white-red with cedar article was changed on 7 December 1943 to red, white and red horizontal stripes with a green cedar.

Not established: 'Unchanged since 1943' is not exact: Wikipedia says the cedar was usually drawn with a brown trunk until a 21 September 1990 amendment made the whole tree green. FOTW says the cedar was officially green from the start; the two differ on that.
