Prohibition is the era in American history when the sale, disruption, and manufacturing of alcohol was illegal. Since selling alcohol was illegal, anyone that wanted to get alcohol was now breaking the law. However whenever there is a good/resource people want, even if it is illegal, they will pay a significant amount of money for it.
When this is the case, people will risk almost anything to make a huge profit. This is why crime and violence increase during Prohibition. Organized crime rings, lead by people like Al Capone, start to form. Due to the high demand of alcohol by American citizens, there became a huge competition between different organized crime groups for customers. Rival gangs would end up in shootouts (like the Valentine's Day Massacre).
