Beginning with the Kingdom of Aksum, Ethiopia's territory evolved significantly through conquest of the lands surrounding it. Strong Aksumite trading partnerships with other world powers gave prominence to its territorial expansion. In 330, Aksum besieged the Nubian city of Meroë, marking the beginning of its great expansion. It finally declined after the rise of Islamic dominion in South Arabia, and it ultimately collapsed in the 10th century.
The Zagwe dynasty emerged and ruled until 1270, when Amhara-Shewan Yekuno Amlak revolted against the last king, Yetbarak, commencing the Solomonic dynasty-led Ethiopian Empire. The empire reached its greatest extent under the emperors Amda Seyon I and Zara Yaqob. In 1896, Emperor Menelik II’s conquest strongly consolidated Ethiopia’s modern borders while eluding the 19th-century Scramble for Africa and Italian colonialism. Eritrea was annexed by the Ethiopian imperial government under Emperor Haile Selassie in 1952, culminating in the Eritrean War of Independence. Eritrea eventually seceded by referendum during its seizure by the Ethiopian People's Revolutionary Democratic Front (EPRDF) in 1993.
