A Guide to the United States' History of Recognition, Diplomatic, and Consular Relations, by Country, since 1776: Brazil
The United States and Brazil have enjoyed long and friendly relations, dating from its years as a Portuguese colony. U.S. merchant ships frequented Brazilian ports such as Pernambuco (now Recife), Bahia (now Salvador), and Rio de Janeiro, and U.S. Consulates appeared in the ports of Pernambuco and Rio de Janeiro in the 1810s. Since Brazil’s independence the United States and Brazil have had good relations, and at the beginning of the twentieth century the U.S.-Brazilian relationship was sometimes characterized as "the unwritten alliance." During World War II Brazil sent the Brazilian Expeditionary Force to assist the U.S.-led Italian Campaign. Since World War II, as Brazil has emerged as a regional power and an important leader in international affairs, the United States and Brazil have enjoyed friendly, strong, and active relations, encompassing a broad political and economic agenda.
