Somali history before 1900 hinged on coastal-hinterland interaction, not coast alone

Evidence

Thus by the middle of the nineteenth century the Somali coast was no longer isolated, and locally it was now rather the nomads of the hinterland who controlled the ports than the other way about. To a large extent the coastal and hinterland traditions had merged, and the centre of political pressure had swung from the coast to the interior. The new external links between the coast and the outside world, however, served in the following decades of the nineteenth century to pave the way for a new colonial impact in which the pressure, initially at least, was again mainly from the coast towards the hinterland. — I.M.

About the time of the overthrow of the Muzaffar dynasty in Mogadishu, it appears, again from local tradition, that much of the zone between the Shebelle and Juba rivers, including Bur Hacaba, was still mainly in Galla hands. Thus the situation was now that, from the coast about Mogadishu westwards towards the hinterland, the country was occupied first by the Hawiye, then by the Galla, and finally by the Rahanweyn Somali. — I.M.

The traditions of migration indicate that in their gradual and by no means co-ordinated movement towards the south the Somali followed two main routes: they descended from the north down the valley of the Shebelle and its tributaries, or along the line of coastal wells on the Indian Ocean littoral. — I.M.
