The Potenji River Conference, also known as the Natal Conference, was a meeting that took place on January 28 and 29, 1943 between the President of Brazil, Getúlio Vargas and the President of the United States, Franklin Delano Roosevelt.[1] On his way back from the Casablanca Conference, the U.S. president paid a visit to the Brazilian president and inspected some of the military installations that were sending aircraft and equipment to the fronts in Africa and Asia.[2] The visit also involved discussions of the ongoing support and role of Brazil in World War II. This conference between the presidents of the two countries took place aboard the USS in the Potenji River harbor in Natal, Rio Grande do Norte[3] and defined the agreements that led to the creation of the Brazilian Expeditionary Force.
