While the Kenya Army's origins date back to the East African Rifles, the name "Kenya Defence Force" was previously used for a separate, colonial settler unit. In 1907 the idea of a white settler defence force was discussed. The Kenya Defence Force was eventually established under the Defence Force Ordinance 1928. The Ordinance "made provision for the compulsory registration of all European males of British nationality in the Colony up to the age of fifty years and for their division into three classes according to age. However, those over fifty could also enrol in a fourth class." After questions were raised about control of weapons and potential settler threats to the Kenya Government in 1936, the Force was disbanded and replaced by the Kenya Regiment, formed 1 June 1937.
