Kenya African National Union nonetheless decided to remove all provisions of a federal nature from the constitution. Kenya became independent on December 12, 1963, and the next year became a republic within the Commonwealth. Jomo Kenyatta, head of the Kenya African National Union, became Kenya's first president. KADU dissolved itself voluntarily in 1964 and joined KANU after a strong lobbying by Tom Mboya. A small but significant leftist opposition party, the Kenya People's Union (KPU), was formed in 1966, led by Jaramogi Oginga Odinga, a former vice president and Luo elder. The KPU was banned and its leader detained after political unrest related to
Jomo Kenyatta whose assumptions about the Kikuyu it challenged. The book reflected Kenyatta's desire to use anthropology as a weapon against colonialism. In it, Kenyatta challenged the Eurocentric view of history by presenting an image of a golden African past by emphasising the perceived order, virtue, and self-sufficiency of Kikuyu society. Utilising a functionalist framework, he promoted the idea that traditional Kikuyu society had a cohesion and integrity that was better than anything offered by European colonialism. In this book, Kenyatta made clear his belief that the rights of the individual should be downgraded in favour of the interests of the group.
