The Prohibition era in the United States lasted from 1920 to 1933, during which the manufacture, sale, and transportation of alcoholic beverages were banned. This period was established by the 18th Amendment and aimed to reduce crime and corruption, improve health, and strengthen families. However, it led to the rise of illegal activities, including bootlegging and speakeasies. The Prohibition era also saw the emergence of organized crime, with figures like Al Capone gaining notoriety for their involvement in the illegal alcohol trade. Ultimately, the negative consequences of Prohibition led to its repeal in 1933 with the 21st Amendment, allowing the legal sale of alcohol once again.
