Britain included the conditional provision that the Somali residents would retain their autonomy, but Ethiopia immediately claimed sovereignty over the area. This prompted an unsuccessful bid by Britain in 1956 to buy back the Somali lands it had turned over. Britain also granted administration of the almost exclusively Somali-inhabited Northern Frontier District (NFD) to Kenyan nationalists. This was despite a plebiscite in which, according to a British colonial commission, almost all of the territory's ethnic Somalis favored joining the newly formed Somali Republic.
