Population pressure, drought, and Islamic fervor drove Somali southern migration

Evidence

Folk tradition today offers little information as to the causes of this movement. It would not be unreasonable to conjecture, however, that mounting population pressure, augmented by continued Arab immigration, and perhaps exacerbated by a series of severe droughts, prompted a general Somali movement in search of new pastures. And this was no doubt furthered by the messianic and militant fervour of early Islam. — I.M. Lewis, I. M. Lewis, A Modern History of the Somali_ Nation…, 92
