Alcohol law

In the United States, there was an attempt from 1919 to 1933 to eliminate the drinking of alcoholic beverages by means of a national prohibition of their manufacture and sale. This period became known as the Prohibition era. During this time, the 18th Amendment to the Constitution of the United States made the manufacture, sale, and transportation of alcoholic beverages illegal throughout the United States.
