Independent Republic of Vanuatu
Who & why: the New Hebrides gain independence from the Anglo-French Condominium on 30 July 1980, taking the new name Vanuatu — from a local phrase meaning roughly "our land forever" — and electing Father Walter Lini, leader of the Vanua'aku Pati, as the nation's first prime minister. Independence arrives only after a brief secessionist crisis on Espiritu Santo that year, put down with the help of Papua New Guinean troops shortly before the transfer of sovereignty.
What it represents: red stands for the blood of ancestors and national unity, green for the islands' richness, and black for the ni-Vanuatu people; the yellow band tracing a rough "Y" recalls the archipelago's own north-south shape, while the black triangle at the hoist carries a boar's tusk encircling two crossed namele-fern leaves — symbols of peace and traditional authority drawn from local custom.
