On March 2, 1877, the House of Representatives ended a filibuster and certified Rutherford B. Hayes as president, resolving the most disputed election in American history. The Compromise of 1877, which made it possible, led to the withdrawal of federal troops from the South, ending Reconstruction. Southern Democrats promised to protect Black civil rights. They lied. Within months, Black Americans across the South began losing the right to vote, hold office, and expect equal treatment. The effects lasted ninety years. This is a story about political compromise, constitutional crisis, and the price of abandoning justice for stability.
