The International Union of American Republics (now called the Pan American Union)—general secretariat of the Organization of American States (OAS)—designated April 14 as Pan American Day in 1930. Although each member country holds its own celebration, it is at the Pan American Union building in Washington, DC, that one of the largest observances takes place. Students from all over the Western Hemisphere travel to Washington where, against a backdrop of flags in the courtyard of the House of the Americas, they perform folk songs and dances. Discuss
