History of Chicago

The ratification of the 18th amendment to the Constitution in 1919 made the production and sale (including exportation) of alcoholic beverages illegal in the United States. This ushered in the beginning of what is known as the Gangster Era, a time that roughly spans from 1919 until 1933 when the Prohibition was repealed. The 1920s saw gangsters, including Al Capone, Dion O'Banion, Bugs Moran and Tony Accardo battle law enforcement and each other on the streets of Chicago during the Prohibition era. Chicago was the location of the infamous St. Valentine's Day Massacre in 1929, where Al Capone sent men to gun down members of his rival gang, North Side, led by Bugs Moran.

In 1924, Chicago was the first American city to have a homosexual-rights organization, the Society for Human Rights. This organization produced the first American publication for gays, Friendship and Freedom. Police and political pressure soon caused it to disband.

In 1933, Chicago Mayor Anton Cermak was fatally wounded in Miami, Florida during a failed assassination attempt on President-elect Franklin D. Roosevelt. In 1933 and 1934, the city celebrated its centennial by hosting the Century of Progress International Exposition Worlds Fair. The theme of the fair was technological innovation over the century since Chicago's founding.
