In the 1860s, it was the Republican Party in Washington — the home of former abolitionists — that sought to grant legal rights and social equality to African-Americans in the South. The Republicans — then dubbed radical Republicans — managed to enact a series of constitutional amendments and reconstruction acts granting legal equality to former slaves — and giving them access to federal courts if their rights were violated.

Charles Sumner of Massachusetts, which guaranteed that everyone in the United States was "entitled to the full and equal enjoyment" of public accommodations and facilities regardless of race or skin color.
