African country, bordering Eritrea, Djibouti, Somalia, Kenya, and Sudan. It's the oldest independent African country, and probably one of the oldest in the world (about 2000 years, according to the CIA World Factbook), although it's gone through a lot of different types of government in that period. It's also one of the least developed countries, and is prone to famine as happened in the 1980s. Currently involved in a war with Eritrea, formerly a part of Ethiopia until 1993, over their border. There is also some disagreement over the border with Somalia.
