Answer:
The event that marks the end of federal Reconstruction and the return of Southern Democrat power in the South is the Compromise of 1877. This compromise was an informal agreement reached between Republicans and Democrats following the disputed 1876 presidential election between Rutherford B. Hayes (Republican) and Samuel J. Tilden (Democrat).
Explanation:
In this agreement, Hayes was declared the winner of the election, but as a concession to the Democrats, the federal government agreed to withdraw its remaining troops from the Southern states. These troops had been stationed in the South since the end of the Civil War as part of the Reconstruction efforts to enforce civil rights and protect African Americans.
With the removal of federal troops, Southern Democrats regained control of state governments and were able to implement policies that oppressed African Americans and solidify white supremacy. This marked the end of federal Reconstruction and the beginning of the Jim Crow era, characterized by segregation, discrimination, and the denial of civil rights to African Americans.
The Compromise of 1877 effectively ended the federal government's commitment to protecting the rights of African Americans in the South and allowed Southern Democrats to reestablish control and maintain power for several decades. It was a pivotal moment in U.S. history that perpetuated racial inequality and had long-lasting consequences for the African American community.
