Prohibition

The history of the rise, rule and fall of the Eighteenth Amendment to the United States Constitution and the entire era it encompassed (1920-33). After nearly a century of activism, Prohibition was intended to improve the lives of all citizens by protecting individuals, families and society at large from the devastating effects of alcohol abuse; but paradoxically it made millions of people rethink their definition of morality.
