A speakeasy is a secret bar or nightclub that became popular during the Prohibition era in the United States, which lasted from 1920 to 1933. During this time, the sale and consumption of alcoholic beverages were illegal, leading to the rise of these hidden establishments. Patrons often needed to know a password or be escorted in to enjoy drinks and entertainment. Speakeasies were typically located in basements or behind unmarked doors, creating an air of exclusivity. They featured jazz music and dancing, reflecting the vibrant culture of the Roaring Twenties. Today, some modern bars use the term "speakeasy" to evoke a sense of nostalgia and secrecy.
