* Widespread public opposition: Prohibition was never popular with the general public, and by the end of the 1920s, most Americans were ready to see it repealed.
* Organized crime: Prohibition led to the rise of organized crime, as criminals made huge profits from bootlegging and other illegal activities.
* Economic problems: Prohibition had a negative impact on the economy, as it caused the loss of jobs in the alcohol industry and related businesses.
* Political pressure: The political pressure to repeal prohibition grew stronger in the early 1930s, as the Democrats made repeal a key issue in the 1932 presidential election.
As a result of these factors, the 21st Amendment to the United States Constitution was ratified in 1933, which repealed the 18th Amendment and ended prohibition.
