The Ethiopian Empire, also formerly known by the exonym Abyssinia, or simply known as Ethiopia, was a sovereign state that historically encompasses the geographical area of present-day Ethiopia and Eritrea from the establishment of the Solomonic dynasty by Yekuno Amlak approximately in 1270 until the 1974 coup d'etat by the Derg, which dethroned Emperor Haile Selassie. By 1896, the empire incorporated other regions such as Hararghe, Gurage and Wolayita, and saw its largest expansion with the federation of Eritrea in 1952. Throughout much of its existence, it was surrounded by hostile forces in the African Horn; however, it managed to develop and preserve a kingdom based on its ancient form of Christianity.

Haile Selassie I was Emperor of Ethiopia from 1930 to 1974. He rose to power as Regent Plenipotentiary of Ethiopia (Enderase) for Empress Zewditu from 1916 until 1930. Haile Selassie is widely considered a defining figure in modern Ethiopian history, and the major figure of Rastafari, a religious movement in Jamaica that emerged shortly after he became emperor in the 1930s. Before he rose to power he defeated Ras Gugsa Welle Bitul of Begemder at the Battle of Anchem in 1928. He was a member of the Solomonic dynasty, which claims to trace lineage to Emperor Menelik I, a legendary figure believed by the claimants to be the son of King Solomon and the Queen of Sheba, who they name as Makeda.
