Blatten Geta Heruy Welde Sellase was an Ethiopian diplomat who was Foreign Minister of Ethiopia from 1930 to 1936 and a writer in Amharic. Bahru Zewde observes that his career "stands out as the great success story ... of the early twentieth-century intellectuals," then continues, "His prolific literary record, his influence with Tafari-Hayla-Sellase and his ascent in the bureaucratic hierarchy were all characterized by an unchequered progression. Edward Ullendorff concurs in this evaluation, describing his oeuvre as "a considerable and distinguished literary output."

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.
