The oaths were what held Mau Mau together. Administered in secret, often at night, the ceremonies bound Kikuyu to the cause through ritual and fear. Participants swore to kill if ordered, to never betray the movement, to reclaim stolen land. The British called the oaths barbaric and obscene. For the Kikuyu, they were a return to pre-colonial forms of accountability. After independence, oathing continued. Politicians used it to enforce loyalty, settle scores, and consolidate power. The practice was officially banned but never disappeared. The oath remains one of the most misunderstood and powerful tools in Kikuyu politics.
