The 18th Amendment exists as a number of precedents. It was the first Amendment to set a time limit for its ratification and for its implementation. And, it is the only Amendment no longer the letter of the law, since it was repealed by the 21st Amendment.
Along with the related Volstead Act, the 18th Amendment prohibited the production, transport, and sale of alcoholic beverages within the borders of the United States and its territories. The Volstead Act dealt with particulars of what constituted an alcoholic beverage and how the 18th Amendment would be enforced. Together, they were known as Prohibition.
Efforts to make alcoholic beverages illegal began early in the history of the United States and came to be known as the temperance movement. Religious in nature, the temperance movement had a large number of women, who were also concerned with domestic violence, which they saw as the direct result of alcohol abuse. It wasn't just women in the temperance movement, though, as men campaigned to ban alcohol as well.
Statewide prohibition efforts became popular, beginning in the early part of the 19th Century. One of the first national temperance organizations was the American Temperance Society (ATS), formed in 1826. Within a decade, the ATS had 1.5 million members.
Maine passed a statewide prohibition law in the mid-19th Century but repealed it a few years later. Such laws were being discussed in other states as well.
In 1873, one of the larger organizations, the Women's Christian Temperance Union (WCTU), issued a call for a ban on the sale of alcohol, a plea echoed by the Anti-Saloon League (ASL) several years later. Members of these organizations and people sympathetic to their cause, men and women, demonstrated publicly against the sale of alcohol. Demonstrations took place where alcohol was sold, at saloons and bars, and at public rallies. The Kansas State Constitution outlawed alcohol in 1881.
The temperance movement was largely nonviolent, although one particularly famous leader, Carrie Nation, made a name for herself by using a hatchet to break saloon mirrors and windows and to split open kegs of beer or whiskey. Arrested several times, she became famous for her temperance tactics.
By 1916, half of the states had prohibition laws on their books, but those laws didn't ban the consumption of alcohol in the home. The 18th Amendment didn't, either, nor did the Volstead Act (officially the National Prohibition Act, named after its sponsor, Andrew Volstead of Minnesota) ban the consumption of alcohol for medicinal or sacramental purposes.
With the approval of the 36th state, Nebraska, on January 16, 1919, the 18th Amendment was the law of the land. As stipulated by its own language, the Amendment took effect 366 days later. In the meantime, Congress had approved the Volstead Act, including a vote by both houses to override a veto by President Woodrow Wilson.
