The Cullen–Harrison Act, named for its sponsors, Senator Pat Harrison and Representative Thomas H. Cullen, enacted by the United States Congress March 21, 1933 and signed by President Franklin D. Roosevelt the following day, legalized the sale in the United States of beer with an alcohol content of 3.2% (by weight) and wine of similarly low alcohol content, thought to be too low to be intoxicating, effective April 7, 1933. Each state had to pass similar legislation to legalize sale of the low alcohol beverages in that state. Roosevelt had previously sent a short message to Congress requesting such a bill. Sale of even such low alcohol beer had been illegal in the U.S. since Prohibition started in 1920 following the 1919 passage of the Volstead Act. Throngs gathered outside breweries and taverns for their first legal beer in many years. The passage of the Cullen-Harrison Act is celebrated as National Beer Day every year on April 7th.
