Hungarian Greek Catholic Church

The Hungarian Greek Catholic Church or Hungarian Byzantine Catholic Church is a metropolitan sui iuris Eastern Catholic particular church in full communion with the Catholic Church. It is headquartered in Debrecen. Its liturgical usage is that of the Byzantine Rite in the Hungarian language.

Hungary's Greek Catholics were originally concentrated in what is now northeastern Hungary. This region was historically inhabited by Byzantine Rite Christians from the Carpathian Mountains . Serbs fleeing the Turkish advance arrived later in what was then Hungary, but most stayed in the area that is now part of Serbia. Later still, when the Turks were driven back from Vienna in 1683 and from Buda and central Hungary in 1686, Ruthenians and Slovaks settled in the abandoned lands of Hungary. They were cared for by the Ruthenian Byzantine Rite Eparchy of Mukacheve . In the 17-18th centuries, during the conflict with Protestants, many Hungarians joined the Greek Catholic Church, and so adopted the Byzantine Rite rather than the Latin, which resulted in a considerable increase in their number.
