In 1814, Gervasio Posadas, the Director of the United Provinces of the Río de la Plata, declared Misiones annexed to Argentina's Corrientes (at this time Argentina was quasi-independent but nominally still a Spanish colony). Argentina did not exert de facto control over Misiones, which was claimed by several countries and effectively governed itself. In 1830 Argentine military forces from Corrientes Province took control of Misiones.
