The Mau Mau Uprising was an insurgency by Kenyan rebels against the British colonial administration that lasted from 1952 to 1960. The core of the resistance was formed by members of the Kikuyu tribe, along with smaller numbers of Embu and Meru. The uprising did not succeed militarily, but did create a rift between the white settler community in Kenya and the Home Office in London that set the stage for Kenyan independence in 1963. It is sometimes called the Mau Mau Rebellion or the Mau Mau Revolt, or in official documents, the Kenya Emergency.
The name Mau Mau for the rebel movement was not coined by the movement itself- they called themselves Muingi ("The Movement"), Muigwithania ("The Understanding"), Muma wa Uiguano ("The Oath of Unity") or simply "The KCA", after the Kikuyu Central Association that created the impetus for the insurgency. Veterans of the independance movement referred to themselves as the "Land and Freedom Army" in English.
