The main goal of Prohibition in America, enacted through the 18th Amendment in 1920, was to reduce crime and corruption, improve health, and enhance the overall moral fabric of society by banning the production, sale, and transportation of alcoholic beverages. Advocates, particularly from the temperance movement, believed that alcohol was the root cause of many social issues, including domestic violence, poverty, and moral decay. They argued that eliminating alcohol would lead to a more productive and virtuous society.

However, the reality of Prohibition was quite different. Instead of reducing crime, it led to the rise of organized crime, bootlegging, and speakeasies, as people sought ways to circumvent the law. The enforcement of Prohibition proved difficult, and public sentiment gradually shifted against it. By the early 1930s, the negative consequences of Prohibition became evident, leading to its repeal in 1933 with the 21st Amendment. Ultimately, while the intention was to create a healthier and more moral society, Prohibition resulted in significant unintended consequences that highlighted the complexities of legislating personal behavior.
