John Camaterus
John X Camaterus was the
Patriarch of Constantinople from
1198 to
1206. He fled to
Thrace with the deposed emperor
Alexius V after the capture of
Constantinople during the
Fourth Crusade in
1204. In
1206 Theodore I Lascaris invited him to
Nicaea where Theodore founded the Byzantine successor state of the
Empire of Nicaea, but John died in the same year. The Crusaders installed a
Latin Patriarch in Constantinople, while Theodore simply created a new Greek Patriarchate in Nicaea, which was eventually restored in Constantinople with the rest of the Empire in
1261.
