Haile Selassie I (Ge'ez: ኃይለ፡ ሥላሴ, "Power of the Trinity") (23 July 1892 – 27 August 1975), born Tafari Makonnen, was Ethiopia's regent from 1916 to 1930 and Emperor of Ethiopia from 1930 to 1974. The heir to a dynasty that traced its origins to the 13th century, and from there by tradition back to King Solomon and Queen Makeda, Empress of Axum, known in the Abrahamic tradition as the Queen of Sheba. Haile Selassie is a defining figure in both Ethiopian and African history.
At the League of Nations in 1936, the Emperor condemned the use of chemical weapons by Italy against his people. His internationalist views led to Ethiopia becoming a charter member of the United Nations, and his political thought and experience in promoting multilateralism and collective security have proved seminal and enduring. His suppression of rebellions among the nobles (mekwannint), as well as what some perceived to be Ethiopia's failure to modernize adequately, earned him criticism among some contemporaries and historians.
