Which is correct, Abyssinia or Ethiopia?

Ethiopia is the ancient name of the country in northeastern Africa. It is of Greek origin and literally means the “land of burnt-face people,” alluding to the dark-skinned people in that region. Homer and other classical Greek writers applied the name vaguely to the lands south of Egypt. Abyssinia is the name commonly applied to Ethiopia by Europeans, It is derived from Arabic habesha, signifying “confused, mixed or mongrel race,” and was originally applied to the country in derision. The inhabitants not only never use the name themselves but resent its application to their country by others. After the coronation of Emperor Haile Selassie in 1930 Ethiopia was revived in diplomatic usage by all countries, including the United States. Addis Ababa, the name of the capital of Ethiopia, is a native phrase literally meaning “new flower.”
