The term Prohibition is pointed a period between 1919 and 1933 in which the United States was prohibited to manufacture, sell and deliver alcoholic beverages. The ban had been fixed by law known as the Volstead Act and the 18th Amendment of the Constitution, which came into force in January 1920. The Volstead Act was intended to moralize the U.S. company (the prohibition is in fact also called the noble experiment ), but in fact allowed the big mafia groups to grow thanks to the proceeds from smuggling alcohol: Prohibition was an age marked by gangsters (like Al Capone), from clashes between criminal gangs and corrupt police teams. The Volstead Act was amended on February 17, 1933 by another law, the Blaine Act, which allowed the sale of alcoholic beverages such as beer read. The law ceased to exist with the ratification of the 21st Amendment on December 5, 1933, which also closed the era of Prohibition.
