Final answer:
The end of Reconstruction in the South was caused by the Compromise of 1877, which allowed Hayes to become president in the disputed election.
Step-by-step explanation:
The end of Reconstruction in the South can be attributed to the deal to allow Hayes, a Republican, to become president in the disputed election of 1876. This deal, known as the Compromise of 1877, signaled the withdrawal of federal troops from the South and effectively ended the Reconstruction efforts.
