Americans celebrate the 75th anniversary of the end of Prohibition of alcohol , remembering the dry spell following a constitutional amendment in 1920.
The nationwide ban on the manufacture, sale, transportation, import and export of intoxicating beverages was brought into law by conservatives for moral and health reasons, and repealed in 1933 on economic grounds.
But to this day, pockets of Prohibition exist in the United States, with entire counties still "dry" and bootleggers still running liquor.
The movement to ban alcohol nationwide gathered steam after World War I and the introduction of income tax in the United States, economist Mark Thornton, a senior fellow at the Ludwig von Mises Institute in Alabama, told AFP.
"Income tax was introduced in 1913, and once the war was over, the world economy going again and revenue was coming in, the alcohol industry no longer had the excuse that it provided a big revenue source for the federal government," he explained.
So in 1920, pushed by conservative temperance advocates, the United States embarked on the 'Noble Experiment,' as Prohibition was called.
Some say the experiment worked, at least in part.
"For a long period following Prohibition, drinking levels stayed down," said Amy Mittelman, who has a doctorate in US history from Columbia University and has authored a book on American beer.
"So if the goal of Prohibition was to moderate or ameliorate the effects of alcohol abuse, then to a certain extent it succeeded," she said.
