What were some of the important changes that occurred to the U. S. during the 1920s?

During the 1920s, some freedoms were expanded while others were curtailed. The 18th Amendment to the Constitution, ratified in 1919, had banned the manufacture and sale of "intoxicating liquors," and at 12 A. M. on January 16, 1920, the federal Volstead Act closed every tavern, bar and saloon in the United States.
