The 12th Democratic National Convention assembled in St. Louis, Missouri, in June 1876, the first political convention held by one of the major American parties west of the Mississippi River. Five thousand people jammed the auditorium in St. Louis with hopes for the Democratic Party's first presidential victory in 20 years. The platform called for immediate and sweeping reforms in response to the scandals that had plagued the Grant administration. Tilden won more than 400 votes on the first ballot and the nomination by a landslide on the second.
