Joachim III of Bulgaria

Joachim III (Bulgarian: Йоаким III) was the Patriarch of the Bulgarian Orthodox Church between c. 1282 and 1300, when the Second Bulgarian Empire reached its lowest point of decline during the reign of the emperors George Terter I, Smilets and Chaka. He was executed for treason by emperor Theodore Svetoslav in 1300. The Church did not recognize his guilt and his name was included in the list of Bulgarian Patriarchs in the Book of Boril. His seat was Tarnovo, the capital of Bulgaria.
