Ethiopia /iːθiˈoʊpiə/ (Amharic: ኢትዮጵያ, ʾĪtyōṗṗyā (About this soundlisten), Afar: Itiyoophiyaa, Ge’ez: ኢትዮጵያ, Oromo: Itoophiyaa, Somali: Itoobiya, Tigrinya: ኢትዮጵያ), officially the Federal Democratic Republic of Ethiopia, is a landlocked country in the Horn of 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 has a total area of 1,100,000 square kilometres (420,000 sq mi) and over 109 million inhabitants and is the 15th-most populous country in the world and the 4th-most populous in Africa. The 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.
Addis Ababa (Amharic: አዲስ አበባ, Addis Abäba IPA: [adˈdis ˈabəba] (About this soundlisten), “new flower”), also known as Finfinne (Oromo: Finfinne “natural spring”), is the capital and largest city of Ethiopia. According to the 2007 census, the city has a population of 2,739,551 inhabitants. As a chartered city, Addis Ababa also serves as the capital city of the Oromia Region. It is where the African Union is headquartered and where its predecessor the Organisation of African Unity (OAU) was based. It also hosts the headquarters of the United Nations Economic Commission for Africa (ECA), as well as various other continental and international organisations. Addis Ababa is therefore often referred to as “the political capital of Africa” for its historical, diplomatic and political significance for the continent. The city lies a few miles west of the East African Rift which splits Ethiopia into two, between the Nubian Plate and the Somali Plate. The city is surrounded by the Special Zone of Oromia and populated by people from different regions of Ethiopia. It is home to Addis Ababa University.
