On this date in 1919, the Volstead Act was vetoed by the otherwise execrable proto-commie President Wilson, but that veto was over-ridden by the House of Representatives the same day. The Senate drove the last nail into the barrel, so to speak, the next day, and American went dry. Officially. More or less.
The Eighteenth Amendment, banning "intoxicating liquors", had been passed on January 18th of that year, but neglected to define intoxicating liquors, so it needed a little help, so to speak.
