Ethiopia derived prestige with its uniquely successful military resistance during the late 19th-century Scramble for Africa, becoming the only African country to defeat a European colonial power and retain its sovereignty.

It was the first independent African member of the 20th-century League of Nations and the United Nations. In 1974, at the end of Haile Selassie's reign, power fell to a communist military dictatorship known as the Derg, backed by the Soviet Union, until it was defeated by the Ethiopian People's Revolutionary Democratic Front, which has ruled since about the time of the collapse of the Soviet Union in 1991.
