Overview
A speakeasy, also called a blind pig or blind tiger, was an illicit establishment that sold alcoholic beverages . Nowadays the term usually refers to a retro style bar that replicates aspects of historical speakeasies.
Speakeasy bars came into prominence in the United States during the Prohibition era (1920–1933, longer in some states). During that time, the sale, manufacture, and transportation (bootlegging) of alcoholic beverages was illegal throughout the United States. Speakeasies largely disappeared after Prohibition ended in 1933. The speakeasy-style trend began in 2000 with the opening of the bar Milk & Honey.
Etymology
The phrase "speak softly shop", meaning a "smuggler's house", appeared in a British slang dictionary published in 1823. The similar phrase "speak easy shop", denoting a place where unlicensed liquor sales were made, appeared in a British naval memoir written in 1844.
The precise term "speakeasy" dates from no later than 1837 when an article in the Sydney Herald newspaper in Australia referred to 'sly grog shops, called in slang terms "speakeasy's" [sic] in this part – Boro Creek.'
