Corrientes Province Corrientes Province Corrientes (, ‘currents’ or ‘streams’; ) is a province in northeast Argentina, in the Mesopotamia region. It is surrounded by (from the north, clockwise): Paraguay, the province of Misiones, Brazil, Uruguay, and the provinces of Entre Rios, Santa Fe and Chaco. Before the arrival of the Spanish conquest, the Kaingang, Charrua and Guaraní lived in a big area that also covered most of the current province of Corrientes. The city of Corrientes was founded on April 3, 1588 by Juan Torres de Vera y Aragón as a mid-stop between Asunción and Buenos Aires; the city flourished thanks to
Pact of San José de Flores in Buenos Aires (rather than in the capital, Paraná). The Buenos Aires government also enjoyed numerous alliances in the hinterland, including that of Santiago del Estero Province (led by Manuel Taboada), as well as among powerful Liberal Party governors in Salta, Corrientes, Tucumán and San Juan. The 1858 assassination of San Juan's Federalist governor, Nazario Benavídez, by Liberals inflamed tensions between the Confederation and the State of Buenos Aires. Relations deteriorated further with the signing of a free trade agreement between the Port of Rosario (the chief Confederate port) and the Port of Montevideo to the detriment of Buenos Aires.
