The United States Revenue Cutter Service was founded on this date by Alexander Hamilton in 1790. Their job as an armed branch of the Treasury Department was to enforce import tariffs and all other maritime laws. In 1915 the Revenue Cutter Service merged with the United States Life-Saving Service to form the United States Coast Guard. The modern Coast Guard is probably best known for their search and rescue operations.
