The Compromise of 1877 was a purported informal, unwritten deal that settled the intensely disputed 1876 U.S. presidential election. It resulted in the United States federal government pulling the last troops out of the South, and formally ended the Reconstruction Era.
After the disputed Presidential Election of 1876, Congress declared Republican Rutherford B. Hayes the winner, but Republicans promised to withdraw remaining troops from Southern states. This marked the end of Reconstruction.
