Haile Selassie I was Emperor of Ethiopia from 1930 to 1974. He rose to power as the Regent Plenipotentiary of Ethiopia (Enderase) under Empress Zewditu between 1916 and 1930.
Widely considered to be a defining figure in modern Ethiopian history, he is accorded divine importance in Rastafari, an Abrahamic religion that emerged in the 1930s. A few years before he began his reign over the Ethiopian Empire, Selassie defeated Ethiopian army commander Ras Gugsa Welle Bitul, nephew of Empress Taytu Betul, at the Battle of Anchem. He belonged to the Solomonic dynasty, founded by Emperor Yekuno Amlak in 1270.
Selassie, seeking to modernise Ethiopia, introduced political and social reforms including the 1931 constitution and the abolition of slavery in 1942.
