Land and naval battles took place in the territories of Bahia, Cisplatina, Rio de Janeiro, Grão-Pará, Maranhão and Pernambuco, which today are part of Ceará, Piauí and Rio Grande do Norte states.
The integration of Latin America has a history going back to Spanish American and Brazilian independence, when there was discussion of creating a regional state or confederation of Latin American nations to protect the area's newly won autonomy. After several projects failed, the issue was not taken up again until the late 19th century, but now centered on the issue of international trade and with a sense of pan-Americanism, owing to the United States of America taking a leading role in the project. The idea of granting these organizations a primarily political purpose did not become prominent again until the post-World War II period, which saw both the start of the Cold War and a climate of international cooperation that led to the creation of institutions such as the United Nations. It would not be until the mid-20th century that uniquely Latin American organizations were created.
The Anglo-French blockade of the Río de la Plata, also known as Paraná War, was a five-year naval blockade imposed by France and the United Kingdom on the Argentine Confederation during the Uruguayan Civil War. It was imposed by the Royal Navy and French Navy in 1845 against the Río de la Plata Basin to support the Colorado Party in Uruguay's civil war, resulting in the closure of Buenos Aires to maritime commerce. The Argentine government, led by Juan Manuel de Rosas, refused to drop their support for the Uruguyan White Party, which supported Argentina's resistance to the blockade. Eventually, both Britain and France ended the blockade, signing the Arana-Southern Treaty in 1849 and 1850 respectively, which acknowledged Argentine sovereignty over its rivers.
