Habesh Eyalet - Importance

Importance

Specific Ottoman interest in Habeshistan arose from its pivotal geographic position in the region: it had ports and coastline on both the Red Sea (and near the Bab-el-Mandeb, where Ottoman blockades could be performed if necessary) and on the Indian Ocean (specifically Zeila and the Somali coast). The Ottoman navy was still relatively weak and in its infancy, so Ottoman land forces would have to capture key areas to ensure that the weak navy would have some influence and strengthen.

Selman also recognized a religious duty to conquer Habesh:

Every year raids are carried out against the infidel Habash, on the path of Allah, by way of the holy war, and they fight hard. To the port of Suakin mentioned above come every year one thousand Arab horses from the land of Sa'id (upper Egypt) and they are sold to the Infidels in the province of Abyssinia. It is related that the Muslims of the Aforesaid Zaila' send letters to the tribesfolk (A'rab) of Suakin asking "why are you selling horses to the Infidels in your country? Through these horses they become powerful and fight against us. Are you, too, not Muslim?"

After the 1517 conquests, the Ottomans also were interested in the region because of the hajj. Having conquered the former Muslim defenders of the hajj, the Ottomans, being the successor of those states, was charged with protecting and providing safe passage to all undertaking the hajj. Portuguese hegemony in the Red Sea and Indian Ocean, however, gave them some control over hajjis. In the same vein, other Muslim states in the region saw the Ottomans as their defenders as Muslim brothers:

The Shah of Hormuz, Sharafaldin, wrote a letter to Sultan Süleyman to provide him with military help in order to expel the Portuguese from Hormuz. The ruler of Gujerat also sought Ottoman military help.

Finally, there was a pre-emptive element to the Ottoman invasion of Ethiopia. If the Portuguese had built fortresses and taken control of the Red Sea ports first (especially Dahlak), they would have controlled the whole region, both directly and through their allies. Despite the possible economic gain from taxing Habesh proper, the Ottomans were more concerned with overcoming and outmaneuvering the Portuguese in the Red Sea and Indian Ocean.
