The United States Marine Corps (USMC) is a desegregated force, made up of troops of all races working and fighting alongside each other. In 1776 and 1777, a dozen Black American Marines served in the American Revolutionary War, but from 1798 to 1942, the USMC followed a racially discriminatory policy of denying African Americans the opportunity to serve as Marines. For more than 140 years, the Marines recruited primarily European Americans and white Hispanics, along with a few Asian Americans.
The USMC opened its doors to blacks in June 1942, with the acceptance of African Americans as recruits in segregated all-black units. Other races were accepted somewhat more easily, joining white Marine units. For the next few decades, the incorporation of black troops was not widely accepted within the Corps, nor was desegregation smoothly or quickly achieved. Spurred by executive orders in 1941 and 1948, the integration of non-white USMC personnel proceeded in stages from segregated battalions in 1942, to unified training in 1949, and finally full integration in 1960.
By 2006, approximately 20% of the USMC was Black American and 15–18% Hispanic; more than the 30 to 31% of the U.S. ratio of minorities in the general population.
In America, blacks fought alongside whites in the Continental Army against Great Britain, and in every war up to the War of 1812. The first black American to fight in a Marine role was John Martin, also known as Keto, the slave of a Delaware man, recruited in April 1776 without his owner's permission by Captain of the Marines Miles Pennington of the Continental brig USS Reprisal. Martin served with the Marine platoon on the Reprisal for a year and a half, involved in hard ship-to-ship fighting, but was lost with the rest of his unit when the brig sank in October 1777.
