By 1916, over half of the U.S. states already had statutes that prohibited alcohol. In 1919, the 18th Amendment to the U.S. Constitution, which prohibited the sale and manufacture of alcohol, was ratified. It went into effect on January 16, 1920.
The 21st amendment repeals the 18th amendment in 1933, and today we call the period that the 18th Amendment was law Prohibition. The 18th amendment was not always unpopular. In fact, some states had already banned alcohol before the 18th amendment.
