View images of speakeasies, flappers, homemade stills, and liquor raids during prohibition. From 1920-1933, the United States was a dry country. The 18th Amendment to the Constitution prohibited the making, transportation, and sale of alcohol. The law, as explained in the Ken Burns’ film Prohibition, “turned law-abiding citizens into criminals.” Americans went to illegal bars, called “speakeasies,” on the sly to drink.

The moral attitudes of the American public loosened.
