Roman Catholic Archdiocese of Paraná
On 13 June 1859, Pope Pius IX established the Diocese of Paraná from the Diocese of Buenos Aires. It lost territory to the Diocese of Santa Fe when it was created in 1897 and the Diocese of Corrientes in 1910. The Diocese of Paraná was elevated to an archdiocese by Pope Pius XI on 20 April 1934. It lost territory two more times when the dioceses of Gualeguaychú (1957) and Concordia (1961) were created.
