In Brazil
While in Brazil, Carlota Joaquina made attempts to obtain the administration of the Spanish dominions in Latin America, a project known as Carlotism. Spain itself was controlled by Napoleon and its kings, her father and brother Ferdinand, were held by Napoleon in France. Carlota Joaquina regarded herself as the heiress of her captured family. Allegedly among her plans was to send armies to occupy Buenos Aires and northern Argentina to style herself "Queen of La Plata". The Portuguese-Brazilian forces, however, only managed to annex the eastern banks of the Rio de la Plata as Cisplatina, which were kept in the Empire of Brazil after 1822 and seceded in 1828 as the Republic of Uruguay.
