Concept
Ethiopia, officially the Federal Democratic Republic of Ethiopia, is a landlocked country located in the Horn of Africa. It shares borders with Eritrea to the north, Djibouti to the northeast, Somalia to the east and southeast, Kenya to the south, South Sudan to the west, and Sudan to the northwest. Ethiopia covers land area of 1,112,000 square kilometres (472,000 sq. miles). , it is home to around 116.5 million inhabitants, making it the 13th-most populous country in the world, the 2nd-most populous in Africa after Nigeria, and the most populated landlocked country on Earth. The national capital and largest city, Addis Ababa, lies several kilometres west of the East African Rift that splits the country into the African and Somali tectonic plates. Anatomically modern humans emerged from modern-day Ethiopia and set out to the Near East and elsewhere in the Middle Paleolithic period. Southwestern Ethiopia has been proposed as a possible homeland of the Afroasiatic language family. In 980 BCE, the Kingdom of D'mt extended its realm over Eritrea and the northern region of Ethiopia, while the Kingdom of Aksum maintained a unified civilization in the region for 900 years. Christianity was embraced by the kingdom in 330, and Islam arrived by the first Hijra in 615. After the collapse of Aksum in 960, a variety of kingdoms, largely tribal confederations, existed in the land of Ethiopia. The Zagwe dynasty ruled the north-central parts until being overthrown by Yekuno Amlak in 1270, inaugurating the Ethiopian Empire and the Solomonic dynasty, claimed descent from the biblical Solomon and Queen of Sheba under their son Menelik I. By the 14th century, the empire grew in prestige through territorial expansion and fighting against adjacent territories; most notably, the Ethiopian–Adal War (1529–1543) contributed to fragmentation of the empire, which ultimately fell under a decentralization known as Zemene Mesafint in the mid-18th century. Emperor Tewodros II ended Zemene Mesafint at the beginning of his reign in 1855, marking the reunification and modernization of Ethiopia.
