Malagasy Republic / Republic of Madagascar
Who & why: Madagascar becomes an autonomous republic within the French Community in 1958, adopting its own flag ahead of full sovereignty, and gains full independence as the Malagasy Republic on 26 June 1960 under President Philibert Tsiranana. The country has continued as a republic since, through several changes of constitution and government (including a Marxist-leaning period in the 1970s-80s and a return to multiparty democracy from the 1990s), under the same national flag throughout.
What it represents: the flag of the Malagasy Republic: Wikipedia says the design was chosen on 15 October 1958 and officially adopted on 21 October 1958 (Flags of the World's colonial page gives 16 October), with a white vertical band at the hoist and red over green horizontal bands. Wikipedia says the colours originally had no meaning and that at adoption they were explained as white for purity, red for sovereignty and green for hope; Flags of the World cites a source saying the red and white recall the Merina Kingdom's flags and the green the Hova class, and notes that an attribution of the green to coastal peoples is doubtful.
Wikipedia: the design was chosen by a technical commission on 15 October 1958 and officially adopted on 21 October 1958, a week after the Malagasy Republic was proclaimed; it describes a white vertical band at the hoist and red over green horizontal bands. FOTW's colonial page says Madagascar adopted a flag on 16 October 1958 similar to the current one, and FOTW's Madagascar page says the coat of arms was adopted on 24 December 1959 and the flag with the arms came later (possibly 1960).

Not established: The sources give 21 October (Wikipedia) and 16 October (FOTW) for the 1958 adoption and FOTW's own Madagascar page has a 1959-60 flag with the arms; the page's account of the colours is contradicted: Wikipedia says the colours originally had no meaning and were explained in 1958 as white purity, red sovereignty, green hope, and FOTW notes that sources disagree on the green (Hova, not coastal peoples).
