Somali migrations shaped clan identity through cultural borrowing from Oromo and Bantu

Evidence

Their power in this region was thus by no means yet broken; and from time to time their raiding parties menaced the Somali religious centre at Bardera, founded in 1820 on the middle reaches of the Juba. Thus the new Darod invaders encountered a formidable neighbour whom, for the present, it was more expedient to appease than to provoke. Hence having gained their protection, parties of Darod clansmen crossed the river as clients and allies of the Oromo. The trans-Juban Oromo seem to have welcomed this new support and to have turned it to advantage in their relations with the turbulent Akamba and Masai to their west. — I.M. Lewis, I. M. Lewis, A Modern History of the Somali_ Nation…, 109 (#corroborates, via linked claim)

But the first major impetus to Somali migration which tradition records is the arrival from Arabia of Sheikh Isma ‘il Jabarti about the tenth or eleventh century and the expansion of his descendants, the Darod clans, from their early seat in the north-east corner of Somaliland. … While present evidence, or to be more precise, its lack, suggests that much of the very detailed tradition which surrounds these two patriarchs is legend, it appears likely that it should be interpreted as reflecting the growth and expansion of the Darod and Isaq clans about this time. For while Darod and Isaq themselves may be legendary figures, there is no doubt about the authenticity of the movements of their descendants. — I.M. Lewis, I. M.
