The experiences gained by Africans in the war, coupled with the creation of the white-dominated Kenya Crown Colony, gave rise to considerable political activity in the 1920s which culminated in Archdeacon Owen's "Piny Owacho" (Voice of the People) movement and the "Young Kikuyu Association" (renamed the "East African Association") started in 1921 by Harry Thuku (1895–1970), which gave a sense of nationalism to many Kikuyu and advocated civil disobedience. Thuku's campaign against the colonial government was short-lived. He was exiled to Kismayu the following year, and it was not until 1924 that the Kikuyu Central Association (KCA) was formed to carry on with Thuku's campaign. From 1924, the Kikuyu Central Association (KCA), with Jomo Kenyatta as its Secretary General focused on unifying the Kikuyu into one geographic polity, but its project was undermined by controversies over ritual tribute, land allocation, the ban on female circumcision, and support for Thuku.The KCA sent Kenyatta to England in 1924 and again in 1931 to air their grievances against the colonial government and its policies.
