Spain was in control of many of the regions in the Americas, to be able to manage these colonies they set up viceroyalties. The viceroyalties controlled the people in their country under Spanish law. Rio de la plata consisted of viceroyalties in Argentina, Bolivia, Paraguay, Perú and Uruguay.One of the major causes that Rio de la plata revolted was because of San Martín. He was trained in Europe and believed in the Enlightenment proposed by many philosophers and brought back the idea to South America. Bolívar also had a major role in the revolutions in South America and ended up working at some point with San Martín in other countries. Argentine, Bolivian, Paraguayan, Peruvian and Uruguayan nationalism had a major role while Spain was the authority in the colonies. Spain, during the exploration period, discovered the Americas they created colonies that today are now independent because they had the guts to rebel against their colony.
