Louisiana Purchase Exhibition

The 1904 Summer Olympic Games were relocated to St. Louis in celebration of the Louisiana Purchase Exhibition, after Chicago had already been chosen to host the games for that year. Organizers of the World's Fair did not want another major event happening that would compete with them, so they began to plan for their own athletic games that were touted to eclipse the Olympics, if they did not move to St. Louis. Once the Chicago OCOG and modern Olympic's founder Pierre de Coubertin learned of this, the games officially made the move to St. Louis.
