Ethiopia is one of the oldest homes of human civilizations in the world. Its capital, Addis Ababa, became the permanent headquarters of the African Union.
In the modern era, it was ruled by an empire founded by Yeku Amlak, and it lasted for seven centuries from 1270 AD until its last ruler, Haile Selassie, was overthrown in a military coup in 1974. After about 17 years of rule, Tigray Front revolutionaries overthrew the rule of Mengistu Haile Mariam in 1991.
