While taking over Mayotte Island, East Africa also eyed the nearby islands of Grande Comore, Anjouan, and Mohéli. Among them, the Sultan of Anjouan was the nominal ruler of the Comoros Islands. The Kingdom of East Africa planned to have a heart-to-heart with the Sultan of Anjouan, sending some of its citizens to the Sultanate of Zanzibar. The future Comoros Islands would become East Africa's Comoros Islands.
Right now, it's not possible, as immigration hasn't been settled yet, so the East African Navy was first responsible for stabilizing the Sultan of Anjouan.
After stabilizing Mayotte Island, the East African Navy immediately headed towards Anjouan. With the cordial visit of Grand Duke Ferdinand and the East African Navy, the Sultan of Anjouan soon signed a treaty with East Africa, making the Comoros Islands a protectorate of East Africa.
