The methods used by the Mau Mau in Kenya to claim farmland were to rebel against British Empire by beginning to harass and attack the settlers and the Kenyans who remained loyal to the colonial administration.
The people of Kikuyu ( members of Mau Mau) were desperate for hunger, misery, disease, overcrowding, explotation and usurpation of their farmland to be colonized.
The first deaths on both sides began a spiral of violence that culminated in the proclamation of the State of Emergency, in 1952, which would lead to one of the bloodiest decolonization wars of the 20th century.
The rebellion did not succeed militarily, but it helped create distrust among the white settlers and the goverment of London, which helped to create the climate that led to the independence of Kenya in 1963.
