Prohibition in the United States ends: Utah becomes the 36th U.S. state to ratify the Twenty-first Amendment to the United States Constitution, thus establishing the required 75% of states needed to enact the amendment. (This overturned the 18th Amendment which had made the manufacture, sale, or transportation of alcohol illegal in the United States.)
