Abyssinia

Abyssinia is a term that referred to a region in the Horn of Africa, usually situated in the northern highlands of modern-day Ethiopia and Eritrea. The term and its derivatives were widely used internationally as an official synonym for Ethiopia until the mid-20th century. A derivative ethnonym, Abyssinian, was often used to refer to the Ethio-Semitic-speaking inhabitants of the highlands of Ethiopia and Eritrea.
