Final answer:
The Compromise of 1877 resolved the electoral deadlock between Hayes and Tilden by ending Reconstruction and withdrawing federal troops from the South.
Step-by-step explanation:
The Compromise of 1877, which resolved the election deadlock between Hayes and Tilden, essentially ended Reconstruction. This compromise resulted from negotiations that promised the withdrawal of remaining U.S. troops from Louisiana and South Carolina, thus enabling Southern Democrats to regain political control and mark the collapse of the post-Civil War Reconstruction governments.
The impact of the Compromise of 1877 was significant: Hayes followed through on his commitments, Reconstruction officially ended, and federal intervention in the South ceased, leaving African Americans vulnerable and marking a long period of disenfranchisement and discriminatory laws known as Jim Crow. While the Compromise resolved an immediate political crisis, it abandoned the promises of Reconstruction, resulting in a discriminatory political and social system that persisted for nearly a century.
