What was Prohibition about in the 1920s?

The banning of the making, selling and drinking of alcohol. Basically it was a ban on alcoholic beverages. No one was allowed to make, sell or drink alcohol. Prohibition was the period between 1919 and 1933 in the United States and Canada, when the manufacture, purchase, transportation, import, export, and sale of alcoholic beverages was prohibited by the Volstead Act (which became law on January 16, 1920), enforcing Amendment 18 to the United States Constitution (which became law on January 16, 1919). It was repealed in 1933 by Amendment 21. Prohibition went into effect on January 16, 1920 and was finally abolished by passage of the Blaine Act on February 17, 1933.
