National Buffalo Soldiers Day on July 28th commemorates the formation of the first regular Army regiments comprising African American soldiers in 1866.
These troops served on the Western frontier after the Civil War. They served in various ways, including security, law enforcement, and other frontier-specific activities. In 1866, Congress passed the Army Organization Act, which formally created six all-Black U.S. Cavalry and infantry units.
In 1992, the United States Congress passed a law designating July 28th as Buffalo Soldiers Day. Since then, commemorations honoring the Buffalo Soldiers have been held throughout the United States.
