Republic of Cape Verde (multi-party)
Who & why: Cape Verde holds its first free multi-party elections in January 1991, peacefully ending sixteen years of one-party PAICV rule, and a new flag is adopted on 22 September 1992. The design is a deliberate, well-documented break from the old red-yellow-green PAIGC symbolism the country had shared with Guinea-Bissau since independence — a fresh national identity for a newly democratized state, not a modification of the old banner.
What it represents: a blue field for the surrounding Atlantic, crossed by a horizontal white-red-white band, with a circle of ten gold five-pointed stars set toward the hoist — each star standing for one of the archipelago's ten main islands, unified in a ring.
