Usage

When was Prohibition? Prohibition refers to a period in American history when the sale, manufacture, and transportation of alcoholic beverages was made illegal. The law, which was created by the Eighteenth Amendment (ratified in 1918) to the United States Constitution and subsequently reversed by the Twenty-first Amendment (ratified in 1933), proved largely unpopular.

Prohibition is often mentioned in discussions of how much social change can be brought about through law, because alcohol was widely, though illegally, produced and sold during Prohibition; it was served privately in the White House under President Warren Harding, for example.

Many use the example of Prohibition to argue that more harm than good comes from the enactment of laws that are sure to be widely disobeyed.

Some states and localities (called “dry”) had outlawed the production and sale of alcohol before the Prohibition amendment was adopted. The repealing amendment allowed individual states and localities to remain “dry,” and some did for many years.

Etymology

Origin of prohibition

First recorded in 1275–1325; Middle English, from Latin prohibitiōn-, stem of prohibitiō “prevention”; equivalent to prohibit + -ion

Explanation

Prohibition is the act of forbidding or outlawing something, like when my mom placed a prohibition on watching TV during dinner (causing everyone to skip dinner). Prohibition can also refer to one of the most famous acts of prohibition in United States history: the outlawing of alcoholic beverages from 1920 to 1933. During this period, known as the "Prohibition Era" or just "Prohibition" for short, people continued to obtain alcohol via illegal means. As a result, the Prohibition Era is a perfect illustration of a major challenge associated with most acts of prohibition: enforcement.
