Religion in the United Provinces of the Río de la Plata (modern Argentina) saw great changes from the religious uses at the Viceroyalty of the Río de la Plata, in the wake of the great social upheavals that took place during the Argentine War of Independence. Although the war was not a religious war, and both patriots and royalists were equally Christian, it was influenced by the ideas of the Age of Enlightenment. The relation with the Holy See through Spain was cut, until being restored by Juan Manuel de Rosas.
