Prohibition was legal prevention of the manufacture, sale, and transportation of alcoholic beverages in the United States from 1920 to 1933 under the Eighteenth Amendment. Despite this legislation, millions of Americans drank liquor illegally, giving rise to bootlegging, speakeasies, and a period of gangsterism.| Encyclopedia Britannica
Moonshine is, traditionally, illicitly distilled liquor, though it is also a product distilled legally today. The word “moonshine” is derived from the notion of the liquor being made and distributed at night, under cover of darkness. Moonshine has also been called rotgut, white lightning, white dog, and corn liquor.| Encyclopedia Britannica
