The 21st Amendment to the U.S. Constitution is ratified, repealing the 18th Amendment and bringing an end to the era of national prohibition of alcohol in America. At 5:32 p.m. EST, Utah became the 36th state to ratify the amendment, achieving the requisite three-fourths majority of states’ approval. Pennsylvania and Ohio had ratified it earlier in the day.
The movement for the prohibition of alcohol began in the early 19th century, when Americans concerned about the adverse effects of drinking began forming temperance societies. By the late 19th century, these groups had become a powerful political force, campaigning on the state level and calling for national liquor abstinence. Several states outlawed the manufacture or sale of alcohol within their own borders. In December 1917, the 18th Amendment, prohibiting the “manufacture, sale, or transportation of intoxicating liquors for beverage purposes,” was passed by Congress and sent to the states for ratification. On January 29, 1919, the 18th Amendment achieved the necessary three-fourths majority of state ratification. Prohibition essentially began in June of that year, but the amendment did not officially take effect until January 29, 1920 (
