The Oromo are one of the Cushitic speaking groups of people with variations in colour and physical characteristics ranging from Hamitic to Nilotic. A brief look at the early history of some of the peoples who have occupied north-eastern Africa sheds some light on the ethnic origin of Oromo. The Cushitic speakers have inhabited north-eastern and eastern Africa for as long as recorded history. The land of Cush, Nubia or the ancient Ethiopia in middle and lower Nile is the home of the Cushitic speakers. It was most probably from there that they subsequently dispersed and became differentiated into separate linguistic and cultural groups. The various Cushitic nations inhabiting north-east and east Africa today are the result of this dispersion and differentiation. The Oromo form one of those groups which spread southwards and then east and west occupying large part of the Horn of Africa. Their physical features, culture, language and other evidences unequivocally point to the fact that they are indigenous to this part of Africa. Available information clearly indicates that the Oromo existed as a community of people for thousands of years in East Africa (Prouty at al, 1981). Bates (1979) contends, "The Gallas (Oromo) were a very ancient race, the indigenous stock, perhaps, on which most other peoples in this part of eastern Africa have been grafted".
