Republic of Kenya
Who & why: Kenya becomes independent on 12 December 1963 under Prime Minister Jomo Kenyatta, leader of the Kenya African National Union (KANU), and a republic within the year with Kenyatta as president. Independence follows the Lancaster House constitutional conferences of the early 1960s, themselves a direct response to the pressure the Mau Mau uprising had put on British colonial policy the decade before.
What it represents: black for the people, red for the blood shed in the struggle for independence, green for the land, separated by thin white fimbriation for peace — adapted directly from KANU's own party flag, with a red, white, and black Maasai shield and two crossed spears laid over the center representing the defense of freedom.
