Prohibition Party
The Prohibition Party's proudest moment came in 1919, with the passage of the 18th Amendment to the United States Constitution, which outlawed the production, sale, transportation, import and export of alcohol. The era during which alcohol was illegal in the United States is known as "Prohibition".

The historian Kenneth D. Rose corroborates historian John Burnham's assertion that during the 1920s "there is no firm evidence of this supposed upsurge in lawlessness" as "no statistics from this period dealing with crime are of any value whatsoever". Rose writes:
During the Prohibition era, rates of absenteeism decreased from 10% to 3%. In Michigan, the Ford Motor Company documented "a decrease in absenteeism from 2,620 in April 1918 to 1,628 in May 1918."
