The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) is a law enforcement agency within the United States Department of Justice. The ATF was formed as a unit of the Bureau of Internal Revenue in 1920, and its name and function have evolved over the years.

The ATF's history traces back to the Bureau of Prohibition in 1920
The ATF, or the Bureau of Alcohol, Tobacco, Firearms and Explosives, is a domestic law enforcement agency within the United States Department of Justice. Its history can be traced back to the Bureau of Prohibition, which was formed as a unit of the Bureau of Internal Revenue in 1920.
The Bureau of Prohibition was tasked with enforcing the Volstead Act, which established Prohibition in the United States. In 1927, it became an independent agency within the Treasury Department, and in 1930, it was transferred to the Justice Department. When Prohibition was repealed in 1933, the Bureau was transferred back to the Treasury Department and became the Alcohol Tax Unit (ATU) of the Bureau of Internal Revenue.
Over the next few decades, the responsibilities of the ATU expanded to include enforcing federal firearms and tobacco tax laws. In 1968, with the passage of the Gun Control Act, the agency changed its name to the Alcohol, Tobacco, and Firearms Division of the IRS. In 1970, Congress enacted the Explosives Control Act, which provided for the close regulation of the explosives industry and designated certain arsons and bombings as federal crimes.
Today, the ATF is responsible for investigating and preventing federal offenses involving the unlawful use, manufacture, and possession of firearms and explosives, as well as acts of arson, bombings, and illegal trafficking and tax evasion of alcohol and tobacco products. The ATF also regulates the sale, possession, and transportation of firearms, ammunition, and explosives through licensing.

The ATF was initially part of the Treasury Department
The ATF, or the Bureau of Alcohol, Tobacco, Firearms and Explosives, is a domestic law enforcement agency within the United States Department of Justice. The ATF was initially part of the Treasury Department, with its origins dating back to the Bureau of Prohibition, formed in 1920 as a unit of the Bureau of Internal Revenue. In 1927, it became an independent agency within the Treasury Department.
The ATF's history is closely tied to the enforcement of alcohol-related laws, initially focusing on the taxation of alcohol and tobacco products. Over time, its responsibilities expanded to include the investigation and prevention of federal offences involving firearms, explosives, arson, bombings, and illegal trafficking. The ATF also regulates the sale, possession, and transportation of firearms, ammunition, and explosives through licensing and enforcement of relevant laws.
In the early 1950s, the Bureau of Internal Revenue was renamed the Internal Revenue Service (IRS), and the ATF's predecessor, the Alcohol Tax Unit (ATU), took on additional responsibilities for enforcing federal tobacco tax laws. This expansion led to the unit being renamed the Alcohol and Tobacco Tax Division (ATTD). With the passage of the Gun Control Act in 1968, the division's name changed to the Alcohol, Tobacco, and Firearms Division, and it began to be referred to as the ATF.
The ATF's role continued to evolve, and in 2001, following the terrorist attacks on the World Trade Center and the Pentagon, President George W. Bush signed the Homeland Security Act into law. This law transferred the ATF from the Department of the Treasury to the Department of Justice, where it remains today. The ATF's current responsibilities include enforcing federal firearms and explosives laws, investigating violent crimes, and regulating the firearms industry, working closely with federal, state, local, and international law enforcement partners.

Its responsibilities include investigating and preventing federal offences involving the unlawful use, manufacture, and possession of firearms and explosives, as well as acts of arson and bombings, and the illegal trafficking and tax evasion of alcohol and tobacco products. ATF also regulates the sale, possession, and transportation of firearms, ammunition, and explosives in interstate commerce.
The ATF was initially formed in 1886 as the "Revenue Laboratory" within the Treasury Department's Bureau of Internal Revenue. In 1920, it was formed as the Bureau of Prohibition, a unit of the Bureau of Internal Revenue. It was made an independent agency within the Treasury Department in 1927, was transferred to the Justice Department in 1930, and became a division of the FBI in 1933. When the Volstead Act, which established Prohibition, was repealed in 1933, the ATF was transferred back to the Treasury Department, where it became the Alcohol Tax Unit (ATU) of the Bureau of Internal Revenue.
In 2001, following the terrorist attacks on the World Trade Center and the Pentagon, President George W. Bush signed the Homeland Security Act of 2002. This law created the Department of Homeland Security and shifted the ATF from the Department of the Treasury to the Department of Justice. The ATF's former tax and trade responsibilities remained under the Treasury's new Alcohol and Tobacco Tax and Trade Bureau.
Since the move, the ATF has focused more on preventing violent crime involving firearms and engaging in other anti-criminal activities. The ATF continues to work closely with federal, state, local, and international law enforcement partners and operates a unique fire research laboratory in Beltsville, Maryland.
