The United States Coast Guard (USCG) had its beginnings in the Lighthouse Service, which handled aids to navigation, and the Revenue Service, which enforced customs laws, under the Treasury Department. In 1915, the USCG was established, combining the Life-Saving Service and the Revenue Cutter Service, and the Lighthouse Service was added to it in 1939. The Coast Guard was under Navy control during WWI and WWII. In 1973, USCG was transferred to the Department of Transportation, where it remained until it was placed in DHS in 2003.
