The American Civil War had cost more than 620,000 lives and had nearly torn the nation apart, but by May 1865, it was finally over. To celebrate, thousands of people gathered in Washington, D.C., to express their gratitude to the military forces that had made the Union victory possible. More than 200,000 Union troops paraded through the city in this Grand Review—but only white troops participated. Even though more than 185,000 African American soldiers had served the Union cause and suffered disproportionately high casualty rates in battle, black soldiers were not invited to the Washington celebration.
