Prohibition was never very popular with the American people. Enforcing it had become a nightmare, with 1,500 agents pursuing tens of thousands of individuals, including members of organized crime who smuggled liquor into the United States.
One of the first acts of the Roosevelt Administration was the repeal of Prohibition. This was done in two-step process. The first step was the "Beer Revenue Act," which legalized beer and wine with an alocohol content of up to 3.2%. The second step was the passage of the 21st Amendment to the Constitution, which legalized liquor once again.
