What is U.S. Coast Guard Birthday?
The U.S. Coast Guard Birthday, August 4, marks the founding of the service that guards U.S. waters, enforces maritime law and carries out search and rescue.
History of U.S. Coast Guard Birthday
On August 4, 1790, at the urging of Treasury Secretary Alexander Hamilton, Congress authorized ten cutters to enforce customs laws, creating the Revenue Cutter Service. It merged with the U.S. Life-Saving Service in 1915 to form the Coast Guard, which later absorbed the Lighthouse Service and other agencies.
