At death, Kenyans believe that one enters the spirit world, which has great influence in the world of the living. Many Kenyans believe in reincarnation, and children are thought to be the embodiment of the souls of a family’s ancestors.

he population is 38 percent Protestant and 28 percent Roman Catholic. Twenty-six percent are animist, 7 percent are Muslim, and 1 percent follow other religions. Many people incorporate traditional beliefs into their practice of Christianity, causing some tension between Kenyans and Christian churches, particularly on the issue of polygamy. Religious practices of different ethnic groups vary, but one common element is the belief in a spirit world inhabited by the souls of ancestors. The Kikuyu and several other groups worship the god Ngai, who is said to live on top of Mount Kenya.
