Question

What was the main cause for the end of reconstruction

Answer 1

APEX: demoncrats had gained enough power to make a change.

Answer 2

Congress was tired of reconstruction and sick of changing the social structure of the South. And, all of the old leaders were dead. There was also a lot of corruption in Grant's administration, and Congress decided stopping corruption was more important. A third reason was because Congress had a new goal to make the US the most powerful, industrial nation in the world and to help big businesses.
