ATF Department Treasury

The ATF was formerly part of the United States Department of Treasury, having been formed in 1886 as the "Revenue Laboratory" within the Treasury Department's Bureau of Internal Revenue. The history of ATF can be subsequently traced to the time of the revenuers or "revenoors" and the Bureau of Prohibition, which was formed as a unit of the Bureau of Internal Revenue in 1920, was made an independent agency within the Treasury Department in 1927, was transferred to the Justice Department in 1930, and became, briefly, a subordinate division of the FBI in 1933.
