Independent Grenada
Who & why: Grenada gains independence from Britain on 7 February 1974 under Premier Eric Gairy, who becomes its first Prime Minister. This same flag flies through the major political upheaval that follows without ever changing: the 13 March 1979 Grenada Revolution, in which Maurice Bishop's Marxist-Leninist New Jewel Movement overthrows Gairy in a coup and installs the People's Revolutionary Government; Bishop's arrest and execution amid internal party conflict in October 1983; and the US-led “Operation Urgent Fury” invasion days later, on 25 October 1983, which ends the revolutionary government and restores parliamentary rule. Every one of these is a change of government, not of flag.
What it represents: a rectangle split into yellow triangles (top and bottom) and green triangles (hoist and fly), framed by a red border with six yellow stars (three along the top, three along the bottom), and a central yellow star on a red disc, with a nutmeg at the hoist. Wikipedia dates adoption to 7 February 1974 (independence day) and Flags of the World to 6 December 1973; both credit Anthony C. George. Wikipedia says the nutmeg was the one feature kept from the previous flag.
Wikipedia: the flag was adopted on 7 February 1974, independence day, replacing a temporary Associated State design (green, yellow, blue bands with a nutmeg); green for vegetation, yellow for the sun, red for harmony and courage, six stars for the parishes, a central star for Carriacou and Petite Martinique, and a nutmeg. Flags of the World: the flag was 'assigned on December 6, 1973, the same day as the Coat of Arms'; its history page says the present flag replaced the associated-state flag at independence.

Not established: The sources differ on the adoption date (6 December 1973 assignment vs 7 February 1974 in force at independence); the caption's 'unchanged since 1974' was not checked against later amendments.
