1920 - 1933 CE
Alcohol prohibition is implemented in the United States

Prohibition, which is defined as the legal prevention of the manufacture, sale, and transportation of alcoholic beverages, was in effect from 1920 to 1933 in the United States (under the Eighteenth Amendment). While the temperance movement did succeed in implementing this legislation, millions of people still drank liquor (distilled spirits) illegally. Liquor was still illegally produced and sold, and many illegal (and secretive) drinking establishments existed. Organized crime took advantage of alcohol prohibition, which led to competition and violent territorial battles between criminal gangs.
