Constantine II (Bulgarian: Константин, Konstantin) ruled as emperor (tsar) of Bulgaria in Vidin from 1397 to 1422. He was born in the early 1370s and died in exile at the Serbian court on 17 September 1422. Constantine II claimed the title Emperor of Bulgaria and was accepted as such by foreign governments, but he is often omitted from listings of rulers of Bulgaria.
