The Maasai people originally lived in the Nilo-Saharan region of what is now Sudan. Over the years, they migrated southwards in search of better farmland and new grazing areas for their cattle. These migrations took them to the high plateaux of Kenya and they eventually settled on the savannah plains of Kenya and northern Tanzania. They quickly adapted to their new environment. They succeeded in following the pastoral ethic to the extreme. They have concentrated on cattle rearing because of the irregularity of rainfall in Tanzania and Kenya, and have completely abandoned cereal growing, for example. Cattle alone provide milk, blood, manure for fuel, clothing and meat. They resisted pressure from the Kenyan and Tanzanian governments to adopt a more sedentary lifestyle. But they have won the right to graze their animals freely. Notably in the Masai Mara parks in Kenya and the Serengeti in Tanzania.
