The Ethiopian Empire, historically known as Abyssinia or simply Ethiopia, was a sovereign state that encompassed the present-day territories of Ethiopia and Eritrea. It existed from the establishment of the Solomonic dynasty by Yekuno Amlak around 1270 until the 1974 coup d'état by the Derg, which ended the reign of the final Emperor, Haile Selassie. In the late 19th century, under Emperor Menelik II, the empire expanded significantly to the south, and in 1952, Eritrea was federated under Selassie's rule. Despite being surrounded by hostile forces throughout much of its history, the empire maintained a kingdom centered on its ancient Christian heritage.
Founded in 1270 by Yekuno Amlak, who claimed to descend from the last Aksumite king and ultimately King Solomon and the Queen of Sheba, it replaced the Agaw kingdom of the Zagwe. While initially a rather small and politically unstable entity, the Empire managed to expand significantly under the crusades of Amda Seyon I (1314–1344) and Dawit I (1382–1413), temporarily becoming the dominant force in the Horn of Africa. The Ethiopian Empire would reach its peak during the long reign of Emperor Zara Yaqob (1434–1468). He consolidated the conquests of his predecessors, built numerous churches and monasteries, encouraged literature and art, centralized imperial authority by substituting regional warlords with administrative officials, and significantly expanded his hegemony over adjacent Islamic territories.
