During the 1920s and 1930s, the prohibition period in the United States led to the rise of criminal organizations like bootleggers who smuggled alcohol. Prohibition agents were tasked with enforcing the ban on manufacturing and selling intoxicating liquors, but many citizens still broke the law to drink. The period was characterized by speakeasies and glamorized gangsters. Prohibition ended in 1933 with the ratification of the 21st amendment.
