The Metropolis of Ancyra continued to be a residential see of the Eastern Orthodox Church until the 20th century, with about 40,000 faithful, mostly Turkish-speaking, but that situation ended as a result of the 1923 Convention Concerning the Exchange of Greek and Turkish Populations. The earlier Armenian genocide put an end to the residential eparchy of Ancyra of the Armenian Catholic Church, which had been established in 1850. It is also a titular metropolis of the Ecumenical Patriarchate of Constantinople.
