York
York (c. 1770–unknown) was an enslaved African American man owned by William Clark who served as a full working member of the Lewis and Clark Expedition from 1804 to 1806. York was the first African American to cross the continent north of Mexico and participate in an exploration of this magnitude. Throughout the journey, York performed the same duties as other Corps members — hunting, portaging, scouting, and voting on key decisions, including the choice of winter camp at Fort Clatsop. He was a source of great fascination to many Native American nations encountered along the route, particularly the Mandan and Arikara, who had never seen a Black man before. Despite his essential contributions to the expedition's success, York was not granted his freedom upon return. He repeatedly petitioned Clark for his liberty in the years that followed; historical accounts differ on when or whether he was eventually freed. York's story represents both the remarkable achievements and the deep contradictions of the early American republic.
