The Brazilian Blockade of the River Plate 1826-1828: Prizes, Politics and International Protest
During the Brazilian-Argentine war of 1826-28, the Brazilian Navy instituted a blockade of the River Plate. They had a respectable naval force, but were hampered by the fact that Argentina’s major trading partners were Britain, the USA and France, all of which had considerable naval and diplomatic clout at their disposal. The blockade was initially effective, but crumbled after the latter two powers refused to recognize it and demanded release of ships that had been detained. Shifting political currents in Brazil eventually gave impetus to concessions and negotiations, but the final settlements were not completed until 1834.
