Answer: The Compromise of 1877.
Explanation: When the Democrats and Republicans decided to make a compromise, it contributed to the Compromise of 1877. The Democrats agreed to support Hayes's election as president and to treat African Americans fairly and to respect their civil rights. The Republicans agreed to withdraw federal troops from the last Southern states and to invest in improving the roads, bridges, and railways in the South. However, both failed to keep their end of the bargain. The Compromise of 1877 demolished the African Americans last hopes of receiving equal rights, which in turn, ended the Reconstruction Era.
Plus, if this question was a Plato question, the correct answer is still the Compromise of 1877.
Have a great day! :)
