The Repeal of Prohibition in the United States was accomplished with the passage of the Twenty-first Amendment to the United States Constitution on December 5, 1933.

In 1919, the requisite number of legislatures of the States ratified the 18th Amendment to the Federal Constitution, enabling national prohibition one year later. Many women, notably members of the Women’s Christian Temperance Union, were pivotal in bringing about national Prohibition in the United States of America, believing it would protect families, women and children from the effects of abuse of alcohol.
