Why is Ethiopia not an Arab country?

Ethiopia is not an Arab country, because it is geographically located in eastern Africa and belongs to an African country, but its earliest residents immigrated from the Arabian Peninsula. EthiopianEmpire, also known as Abyssinia, is an East African country from 1270 to 1974. It is the predecessor of the contemporary East African countries, namely the Federal Democratic Republic of Ethiopia and Eritrea. Abyssinia Empire was the only two countries that remained independent from Liberia in the wave of imperialist partition of Africa until the end of World War II. Different from ordinary African countries, Ethiopia's ancient monarchy and system were preserved before the Italian invasion in World War II (1936- 194 1) and were not swallowed up by the colonial tide. The Ethiopian Empire was overthrown by mengistu in 1974.
