Analysis of information sources in references of the Wikipedia article "Joseph II of Constantinople" in English language version.
Joseph II, patriarch of Constantinople (1416-1439), was born ca. 1360 in Bulgaria, perhaps the illegitimate son of the future Bulgar tsar Sisman and a Greek mother. He became patriarch of Constantinople on 21 May 1416 after serving as metropolitan of Ephesus. Thus he was almost eighty years old when he died.
