Black sailors served in the Continental Navy during the Revolutionary War and in the U.S. Navy from its founding in the 1790s. During the War of 1812, Black sailors comprised an estimated 10–20% of naval crews. Commodore Oliver Hazard Perry, after his victory at the Battle of Lake Erie in 1813, specifically praised his Black sailors' performance. Historian Carter Woodson documented that the early Navy was more racially integrated than the Army, primarily because ships required all available hands and couldn't afford racial exclusion as easily as land forces.
This integration was always of a specific kind: Black sailors served as seamen, cooks, and mess attendants — never as officers. The Naval Act of 1798 did not explicitly bar Black men from officer commissions, but no Black man received one. The practice of exclusion hardened over the 19th century, accelerating after the Civil War when the Navy was reorganized. By the 1890s, Black sailors were being systematically confined to the "messman's branch" — roles as cooks and servants for white officers — through Navy regulations. By 1919, a Navy policy directive formally restricted Black sailors almost entirely to messman duty. The U.S. Navy had institutionalized a servant class, and it was Black.
"The Navy accepts no colored men except in the messman's branch."
