Kingdom of Thessalonica
Following the Fourth Crusade and Thessaly's incorporation into the Kingdom of Thessalonica, a Roman Catholic archbishop was installed in the place of the previous Greek Orthodox metropolitan. The city was soon recovered by the Greek Despotate of Epirus, however, possibly as early as 1212, and the Greek Orthodox metropolitan restored. At the close of the 15th century, under the Turkish domination, there were only ten suffragan sees, which gradually grew less and finally disappeared.
