William Bainbridge was a commodore in the United States Navy. During his long career in the young American Navy he served under six presidents beginning with John Adams and is notable for his many victories at sea. He commanded several famous naval ships, including USS Constitution, and saw service in the Barbary Wars and the War of 1812. Bainbridge was also in command of USS Philadelphia when she grounded off the shores of Tripoli, Libya in North Africa, resulting in his capture and imprisonment for many months. In the latter part of his career he became the U.S. Naval Commissioner.

USS Constitution, also known as Old Ironsides, is a three-masted wooden-hulled heavy frigate of the United States Navy. She is the world's oldest commissioned naval warship still afloat. She was launched in 1797, one of six original frigates authorized for construction by the Naval Act of 1794 and the third constructed. The name "Constitution" was among ten names submitted to President George Washington by Secretary of War Timothy Pickering in March of 1795 for the frigates that were to be constructed. Joshua Humphreys designed the frigates to be the young Navy's capital ships, and so Constitution and her sister ships were larger and more heavily armed and built than standard frigates of the period. She was built at Edmund Hartt's shipyard in the North End of Boston, Massachusetts. Her first duties were to provide protection for American merchant shipping during the Quasi-War with France and to defeat the Barbary pirates in the First Barbary War.
