In the vacuum that followed the 1889 death of Emperor Yohannes II, Gen. Oreste Baratieri occupied the highlands along the Eritrean coast and Italy proclaimed the establishment of the new colony of Italian Eritrea, a colony of the Kingdom of Italy. In the Treaty of Wuchale (It. Uccialli) signed the same year, King Menelik of Shewa, a southern Ethiopian kingdom, recognized the Italian occupation of his rivals' lands of Bogos, Hamasien, Akkele Guzay, and Serae in exchange for guarantees of financial assistance and continuing access to European arms and ammunition. His subsequent victory over his rival kings and enthronement as Emperor Menelek II (r. 1889–1913) made the treaty formally binding upon the entire territory.
