During the January 16th, 1920’s the Volstead Act became the 18th amendment. This temperance movement banned alcohol, resulting in a division of the nation into two sides. One supporting the temperance movement, and the other against it. This supporters of this ban of alcohol did plenty to preserve their entertainment. Illegal bars and speakeasies were opened, despite the tracking of alcoholic tenders. This led to an uprise in crime and even corruption in the police force, where officers were bribed to look away from illegal activities. This ban, America realized, was not working out so alcohol became legal again.
The narrator of the documentary sounds like a male historian that studied the prohibition and deplored the banning of alcohol.
Based on the music and narration, the documentary seems to have been produced during the mid to late 1900s
