Ethiopia, officially the Federal Democratic Republic of Ethiopia (FDRE), is a landlocked country located in the Horn of Africa region of East Africa. It shares borders with Eritrea to the north, Djibouti to the northeast, Somalia to the east, Kenya to the south, South Sudan to the west, and Sudan to the northwest. Ethiopia covers a land area of 1,104,300 km2 (426,400 sq mi). As of 2025, it has around 135 million inhabitants, making it the 14th-most populous country. 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. In 980 BC, the Kingdom of D'mt extended its realm over Eritrea and the northern region of Ethiopia, while the Kingdom of Aksum maintained a unified civilisation in the region for 900 years. Christianity arrived to the kingdom in 330 AD, while Islam gained influence during the first Hijra in 615. After the collapse of Aksum in 960, the Zagwe dynasty ruled the north-central parts of Ethiopia. The Shewan usurper, Yekuno Amlak, overthrew the dynasty in 1270 at the Battle of Ansata, inaugurating the Ethiopian Empire and the Solomonic dynasty – asserting its lineage through Aksumite legitimacy by the biblical Solomon and Queen of Sheba, and Menelik I was the first emperor. By the 14th century, the empire had grown 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 decentralisation 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 modernisation of Ethiopia.
In the late 19th century, Ethiopia repelled foreign invasions from both Egypt and Italy, most notably defeating an Italian invasion at the Battle of Adwa in 1896. Under Emperor Menelik II, it also expanded its territory, remaining independent during the Scramble for Africa and establishing its current borders. Ethiopia lost its sovereignty in 1936, when Italy under Benito Mussolini invaded during the Second Italo-Ethiopian War, and following Ethiopia's defeat, Italian East Africa was established. In 1941, during World War II, it was liberated by the British Army, and its full sovereignty was restored in 1944. The Derg, a Soviet-backed military junta, took power in 1974 after deposing Emperor Haile Selassie and the Solomonic dynasty, and ruled the country for nearly 17 years amidst the Ethiopian Civil War. Following the dissolution of the Derg in 1991, the Ethiopian People's Revolutionary Democratic Front (EPRDF) dominated the country with a new constitution and ethnic-based federalism. Since then, Ethiopia has suffered from prolonged and unsolved inter-ethnic clashes and political instability marked by authoritarianism. From 2018, regional and ethnically based factions carried out armed attacks in multiple ongoing wars throughout Ethiopia.
Ethiopia is a multi-ethnic state with over 80 different ethnic groups. Christianity is the most widely professed faith in the country, with the largest denomination being the Ethiopian Orthodox Tewahedo Church, followed by Islam and a small percentage of traditional faiths. The country is a founding member of the UN, and hosts the headquarters of the African Union Commission and many other global non-governmental organisations focused on Africa, also becoming a full member of BRICS in 2024. Ethiopia is one of the least developed countries but is sometimes considered an emerging power, having the fastest economic growth in sub-Saharan African countries because of foreign direct investment in expansion of agricultural and manufacturing industries; agriculture is the country's largest economic sector, accounting for over 37% of the GDP as of 2022. Though the Ethiopian economy has experienced consistent growth, in terms of per capita income and the Human Development Index the country remains among the poorest in Africa.[31] Ethiopia faces numerous challenges, including high rates of poverty, human rights violations, widespread ethnic discrimination, and a literacy rate of 60%.
