Ethiopian rule expanded in the Ogaden because of the campaign. [fact]
The Sayyid's campaigns had also engendered a tradition of Anglo-Ethiopian collaboration against Somali and had drawn the slender arm of Ethiopian rule farther into the Ogaden, thus considerably strengthening Ethiopia's position in relation to Somali. No doubt this would have happened eventually without British support and prompting, but its occurrence at this time, and in these circumstances, was one of the paradoxical consequences of the Dervish fight for freedom. Hence, although Sayyid Muhammad's image was at the time of his death, and still remains, that of a national hero and patriot, his holy war – despite all the courage and tenacity of his supporters – not only failed in its purpose of driving the 'infidels' into the sea, but actually led to a further extension and entrenchment of alien rule.
