PROHIBITION is a three-part, five-and-a-half-hour documentary film series directed by Ken Burns and Lynn Novick that tells the story of the rise, rule, and fall of the Eighteenth Amendment to the U.S. Constitution and the entire era it encompassed.
Prohibition was intended to improve, even to ennoble, the lives of all Americans, to protect individuals, families, and society at large from the devastating effects of alcohol abuse. But the enshrining of a faith-driven moral code in the Constitution paradoxically caused millions of Americans to rethink their definition of morality.
Note: The Eighteenth amendment was an example of an amendment to the constitution that didn't work properly (prohibiting alcohol). The first 10 amendments are part of the Bill of Rights which can be considered to be part and parcel of the original constitution (at least, I haven't heard any arguments that would explain - with evidence - otherwise).
