Inter-American Conference on Problems of War and Peace

The Inter-American Conference on Problems of War and Peace informally known as the Chapultepec Conference, was held in Chapultepec Castle in Mexico City on February 21 to March 8, 1945, between the United States and 19 Latin American countries. Argentina was not invited because it had not declared war on the Axis Powers in World War II. The original goals were to discuss the status of Argentina, the role of the United Nations and postwar American economic aid.
