The Sultan of Zanzibar's ten-mile coastal strip
When Britain took over the East Africa Protectorate, the narrow ten-mile-deep coastal strip legally belonged not to Britain but to the Sultan of Zanzibar, whose dominion Britain leased and administered on his behalf. The coast was therefore governed as the Sultan's territory under British protection, a status distinct from the interior. This split ownership set the coast on a separate legal and political track from the rest of Kenya.
