Ras (Amharic: ራስ, romanized: ras, lit. 'head' compare with Arabic Rais or Hebrew Rosh), is a royal title in the Ethiopian Semitic languages. It is one of the powerful non-imperial titles. Historian equates the Ras title to a duke; others have compared it to "prince". The combined title of Leul Ras (Amharic: ልዑል ራስ) was given to the heads of the cadet branches of the Imperial dynasty, such as the Princes of Gojjam, Tigray, Ras Tafari Makonnen and the sub-branch of the last reigning Shewan Branch, and meaning "Lord of Lords", the highest title of lord.
