The first conflicts between the Roman Catholic Church and the Argentine government can be traced to the ideas of the May Revolution of 1810. The Tribunal of the Inquisition was suppressed in the territories of the United Provinces of the River Plate on 23 March 1813, and on 4 June the General Assembly declared the state "independent from any ecclesiastical authorities existing outside its territory". The framers of the 1853 Constitution, who were in many cases influenced by Freemasonry, found a middle way between an officially Catholic country and a secular society, by allowing religious freedom while keeping economic support for the Church, and employing the patronage system, by which the President selected triplets of bishop candidates that the Pope could approve. This system was abolished in 1966, during the dictatorial rule of Juan Carlos Onganía, and replaced by a Concordat which gave the Vatican the attribution of appointing and removing bishops, leaving the President only with the right to object the appointments. In the 1994 constitutional reform the Concordat was awarded the rank of international treaty and thus given priority over national laws, although Congress is still allowed to reformulate it. The same reform eliminated the constitutional requirement for the President to be a Roman Catholic. The protocol of the Argentine government has always been influenced by the Catholic Church. Bishops often have a place along ministers, governors and other officials in patriotic ceremonies. On the celebration of the May Revolution, the president along with his or her spouse and ministers is expected to attend the Te Deum celebrated by the Archbishop of Buenos Aires. Early times During the first twenty years after the May Revolution, the new state did not establish official diplomatic relations with the Vatican. The Papacy did not wish to create a conflict with the Spanish Crown by showing support for the South American revolution; in 1825, Pope Leo XII denounced it. During the government of Martín Rodríguez (1820–1824), there was a (failed) project to transfer the clergy to state control and abolish tithing in favour of state financial backing for the Church. Juan Manuel de Rosas destroyed the possibility of re-establishing relations when, in 1837, he dictated that no civil or ecclesiastic authority in Buenos Aires Province must acknowledge or obey pontifical documents dated after 1810-05-25 without an authorization granted by the foreign relations department. After Rosas's fall, Justo José de Urquiza proposed the
