What was introduced in the US during the years of 1919-1933?

During the years 1919-1933, the United States experienced Prohibition, a nationwide constitutional ban on the production, importation, transportation, and sale of Alcoholic Beverages, enacted through the 18th Amendment in 1920. This period saw a rise in organized crime and speakeasies as people sought illegal ways to obtain alcohol. Prohibition ultimately led to significant social and political changes, culminating in its repeal with the 21st Amendment in 1933. Additionally, this era encompassed the Great Depression, which began in 1929, profoundly impacting the economy and society.
