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 in 1360 in Bulgaria, perhaps the illegitimate son of the future Ivan Shishman of Bulgaria and a Greek mother. He became patriarch of Constantinople on 21 May 1416 after serving as Metropolis of Ephesus. Thus he was almost eighty years old when he died.
