Haile Selassie I was Emperor of Ethiopia from 1930 to 1974. He rose to power as Regent Plenipotentiary of Ethiopia (Enderase) for Empress Zewditu from 1916 until 1930. Haile Selassie is widely considered a defining figure in modern Ethiopian history, and the major figure of Rastafari, a religious movement in Jamaica that emerged shortly after he became emperor in the 1930s. Before he rose to power he defeated Ras Gugsa Welle Bitul of Begemder at the Battle of Anchem in 1928. He was a member of the Solomonic dynasty, which claims to trace lineage to Emperor Menelik I, a legendary figure believed by the claimants to be the son of King Solomon and the Queen of Sheba, who they name as Makeda.

The Second Italo-Ethiopian War, also referred to as the Second Italo-Abyssinian War, was a war of aggression waged by Italy against Ethiopia, which lasted from October 1935 to February 1937. In Ethiopia it is often referred to simply as the Italian Invasion, and in Italy as the Ethiopian War. It is seen as an example of the expansionist policy that characterized the Axis powers and the ineffectiveness of the League of Nations and Italy's Military before the outbreak of the Second World War.
