Who is Colonel Charles Young best known as?

Colonel Charles Young is best known as the first African American military officer in the U.S. Army, a significant achievement in a time when racial discrimination was rampant. He became a second lieutenant in 1894, earning his commission after graduating from the U.S. Military Academy at West Point. Young's career was marked by several notable milestones, including serving in various capacities, such as the head of a black cavalry regiment, and being part of an expedition to the Mexican border. His contributions to the military and his status as a pioneer for African Americans in this field make him a notable figure in U.S. history.

In contrast, the other options refer to individuals who achieved different historical landmarks. The first African American to serve in Congress was Hiram Revels. The first to win a major combat award would be a separate designation likely pointing to someone recognized for bravery in battle, and the first African American governor was P.B.S. Pinchback of Louisiana. Thus, Young’s significance lies specifically in his historic role as a military officer, making the choice of him as the first African American military officer distinctly accurate.
