Dawit II, also known by the macaronic name Wanag Segad, better known by his birth name Lebna Dengel, was Emperor of Ethiopia from 1508 to 1540, whose political center and palace was in Shewa.

The emperor of Ethiopia, also known as the Atse, was the hereditary ruler of the Ethiopian Empire, from at least the 13th century until the abolition of the monarchy in 1975. The emperor was the head of state and head of government, with ultimate executive, judicial and legislative power in that country. A National Geographic article from 1965 called imperial Ethiopia "nominally a constitutional monarchy; in fact [it was] a benevolent autocracy".
