The cultural changes played a part in significant southward expansion of Loikop territory from a base east of Lake Turkana. This expansion led to the development of three groupings within Loikop society. The Sambur who occupied the 'original' country east of Lake Turkana as well as the Laikipia plateau. The Uasin Gishu occupied the grass plateaus now known as the Uasin Gishu and Mau while the Maasai territory extended from Naivasha to Kilimanjaro. This expansion was subsequently followed by the Iloikop wars.
