Bulgarian Catholic Apostolic Vicariate of Constantinople

The Bulgarian Catholic Apostolic Vicariate of Constantinople (informally Constantinople of the Bulgarians) was the first missionary, pre-diocesan jurisdiction of the Bulgarian Greek Catholic Church sui iuris (Eastern Catholic of Byzantine Rite in Bulgarian language). As Apostolic Vicariate it was exempt, i.e. directly dependent on the Holy See, and entitled to a titular bishop. It was created in 1861 and reorganized in 1883.
