Latin-rite Catholics in Romania are members of an ethnic Hungarian minority, a small community surrounded by Orthodox Christians in one of Europe’s most religiously observant societies. Catholics live mostly in homogenous enclaves in the eastern part of the Transylvania region. There is a sense that these areas are a kind of Catholic homeland. There is a widely-known legend (believed by many ordinary Catholics to be historically true) that the Virgin Mary appeared to a group of Catholics defending this region against an invading Protestant army. An annual pilgrimage to the site of this apparition helps bolster the sense that Catholicism has a “home” in this region.
