The United States Constitution has been amended 27 times, with the most recent amendment being added in 1992. The process of amending the Constitution is outlined in Article V, which requires a proposal by two-thirds of the House and Senate or a constitutional convention called for by two-thirds of state legislatures. For an amendment to become operative, it must be ratified by three-fourths of the states. Only one amendment has ever been repealed by the states, and that is the Eighteenth Amendment, which prohibited the manufacture, sale, and transportation of intoxicating liquors. This amendment was repealed by the Twenty-first Amendment, which was ratified on December 5, 1933.

The Eighteenth Amendment, which prohibited the manufacture, sale, and transportation of alcohol, was repealed by the Twenty-first Amendment
The Eighteenth Amendment to the United States Constitution, which prohibited the manufacture, sale, and transportation of alcohol, was ratified on January 16, 1919. It was the result of a long campaign by the temperance movement, which argued that banning alcohol would eliminate poverty and improve social conditions. The amendment was enforced by the Volstead Act, which defined "intoxicating liquors" as beverages containing 0.5% or more alcohol by volume. It also allowed licensed production, use, and sale of alcohol for specific purposes, such as industrial, medicinal, religious, and scientific reasons.
Despite the amendment, many Americans continued to drink, and a profitable black market for alcohol emerged, leading to the rise of organised crime. The amendment also caused an increase in crime in many large cities, including Chicago, New York, and Los Angeles. The rise of illegal alcohol distribution through speakeasies, bootlegging, and illegal distilling operations also posed challenges for law enforcement. Public sentiment turned against Prohibition by the late 1920s, and the Great Depression further hastened its demise as people argued that the ban denied jobs and revenue to the government.
In response to growing opposition, the Twenty-first Amendment was proposed by Congress on February 20, 1933, to repeal the Eighteenth Amendment. This was the first time in history that an amendment was sent out for ratification by state ratifying conventions rather than state legislatures. The Twenty-first Amendment was officially ratified and added to the U.S. Constitution on December 5, 1933, marking the end of Prohibition. President Franklin D. Roosevelt issued a proclamation expressing his trust in the American people to practice temperance and not abuse alcohol.
The Twenty-first Amendment is unique among the amendments to the U.S. Constitution, as it is the only one to repeal a prior amendment. It also modified the Volstead Act to permit the sale of beer. While the ban on alcohol was lifted, Section 2 of the Twenty-first Amendment implies that states are responsible for regulating the sale, manufacture, and transportation of alcohol.

The Twenty-first Amendment is the only amendment to have repealed a prior one and the only one ratified by state conventions
The Twenty-first Amendment to the United States Constitution is unique for two reasons. Firstly, it is the only amendment to have repealed a prior one, and secondly, it is the only amendment ratified by state conventions.
The Eighteenth Amendment, ratified in 1919, prohibited the manufacture, sale, or transportation of alcohol nationwide. However, Prohibition, as it was known, proved unpopular, and many Americans continued to drink. This gave rise to a profitable black market for alcohol, fuelling the rise of organised crime. As opposition to the amendment grew, a political movement for its repeal emerged.
The Twenty-first Amendment, proposed by Congress in February 1933, included an unprecedented provision: state conventions, rather than state legislatures, would be called for ratification votes. This was due to the fear that the temperance lobby would influence state lawmakers. On December 5, 1933, Utah's state convention unanimously ratified the amendment, officially adding it to the Constitution.
The Twenty-first Amendment is a rare example of a constitutional amendment being repealed. The odds of such an event occurring are estimated to be extremely low, similar to the chances of an 80-year-old being struck by lightning. The amendment's repeal demonstrates the significant shift in public opinion against Prohibition and the unusual steps taken to navigate the political landscape of the time.

The Eighteenth Amendment led to a rise in organised crime and a vast army of lawbreakers
The Eighteenth Amendment to the United States Constitution, which established the prohibition of alcohol, was ratified on January 16, 1919. The amendment was the result of years of advocacy by the temperance movement, which argued that banning alcohol sales would reduce poverty and societal issues. While the amendment did lead to a decline in alcohol consumption, it also had several unintended consequences, including a rise in organised crime and a vast army of lawbreakers.
The enforcement of nationwide prohibition proved challenging, particularly in urban areas, where most people opposed the ban. As a result, illegal activities such as alcohol smuggling (rum-running or bootlegging) and illicit bars (speakeasies) became prevalent. The production and sale of alcohol were increasingly controlled by criminal organisations such as the Mafia and gangs like Al Capone's in Chicago. These groups bribed police and politicians to turn a blind eye to their activities and reaped enormous profits from the illicit liquor trade.
The federal government struggled to enforce the Volstead Act, which was passed to provide for the federal enforcement of Prohibition. Prisons became overcrowded, leading to fewer arrests for alcohol-related offences and smaller fines for those arrested. The murder rate initially fell but then rose to record highs due to gangland killings. Overall, crime rates soared, with a 24% increase in crimes such as assault, theft, and burglary.
As public sentiment turned against Prohibition during the 1920s, a movement to repeal the Eighteenth Amendment gained momentum. The Twenty-first Amendment, which repealed the Eighteenth Amendment, was ratified in 1933. It is the only constitutional amendment in American history to have been repealed. The Twenty-first Amendment not only repealed the Eighteenth Amendment but also banned the importation of alcohol into states and territories with laws prohibiting alcohol.
In conclusion, the Eighteenth Amendment's prohibition of alcohol had far-reaching consequences, including a significant rise in organised crime and a vast number of people breaking the law. The amendment's failure to curb alcohol consumption and the resulting increase in criminal activity ultimately led to its repeal by the Twenty-first Amendment.

The Twenty-first Amendment was proposed by the 72nd Congress on February 20, 1933, and ratified by the required number of states on December 5, 1933
The Twenty-first Amendment to the United States Constitution was proposed by the 72nd Congress on February 20, 1933, and ratified by the required number of states on December 5, 1933. It is the only amendment to the US Constitution that has repealed a prior amendment. In this case, it repealed the Eighteenth Amendment, which had established nationwide prohibition on alcohol.
The Eighteenth Amendment was ratified on January 16, 1919, after a sustained campaign by the temperance movement. However, Prohibition, as it became known, proved unpopular, and many Americans continued to drink. This gave rise to a profitable black market for alcohol, fuelling the rise of organised crime. As a result, by the early 1930s, there was a growing political movement for its repeal.
The process of amending the US Constitution is detailed in Article Five of the Constitution. It requires that an amendment be proposed by two-thirds of the House and Senate or by a constitutional convention called for by two-thirds of state legislatures. In the case of the Twenty-first Amendment, it was proposed by Congress and sent to the states for ratification. This is one of two methods provided by the US Constitution for ratifying amendments.
To become part of the Constitution, an amendment must be ratified by three-fourths of the states. In the case of the Twenty-first Amendment, it was ratified by state ratifying conventions, making it unique among the 27 amendments of the US Constitution. The amendment was officially added to the Constitution on December 5, 1933, when Utah's state convention unanimously ratified it.

The Eighteenth Amendment was ratified in 1919 after advocacy by the temperance movement
The Eighteenth Amendment to the United States Constitution, which established the prohibition of alcohol, was ratified on January 16, 1919. The amendment prohibited the production, transport, and sale of intoxicating liquors, although it did not make the consumption of alcohol illegal. The Eighteenth Amendment was the culmination of years of advocacy by the temperance movement, which argued that banning alcohol would address societal issues such as poverty, immoral sexual behaviour, and violence. The movement also aimed to reduce alcohol consumption to prevent alcoholism and drunkenness.
The roots of the temperance movement can be traced back to the colonial era, with early temperance advocates promoting moderate consumption with the hope of eventually achieving prohibition. By the mid-1830s, over 200,000 people belonged to the American Temperance Society. The movement gained significant support from women, who were often affected by the negative consequences of alcoholism in their family members.
The Anti-Saloon League (ASL), founded in 1906, played a pivotal role in the campaign for prohibition. They argued that banning the sale of alcohol would lead to happier families, reduced workplace accidents, and overall societal improvement. The ASL's efforts, along with those of other groups such as the Woman's Christian Temperance Union, resulted in 23 states enacting laws against alcohol and saloons by 1916.
The proposed amendment was passed by the Senate on December 17, 1917, and issued to the states for ratification the next day. Nebraska became the 36th state to approve it, leading to the ratification of the amendment in 1919. To enforce the amendment, Congress passed the National Prohibition Act, also known as the Volstead Act, on October 28, 1919, which set the start date for nationwide prohibition as January 17, 1920.
Despite the initial support for prohibition, it eventually led to an increase in crime and the emergence of a profitable black market for alcohol, contributing to the rise of organised crime. As a result, the Eighteenth Amendment was repealed by the Twenty-first Amendment on December 5, 1933, marking the only time in American history that a constitutional amendment has been repealed.
