Explanation:
A variety of factors led to the Collapse of the Reconstruction period. Factors such as the Supreme Court rulings. These involved extremely short sighted - and limited rulings involving the civil liberties of African-Americans.
Another defining factor was the weakening and eventual end of the Freedman's Bureau. The FB had worked as a support for the recently freed slaves.
The shift from the radical Republican representation in Congress to the Liberal/Republican party led to the collapse as well given their party was not as interested in showing support to the slaves who had been recently freed.
All in all, there are 4 primary factors that can be designated to have affected the Reconstruction causing it to fail.
1) <u><em>Violence from Confederate loyalists.</em></u><em> </em>This placed African-Americans and supporters in danger.
2) <em><u>Thousands of white plantation owners suffered from extreme poverty. </u></em>War expenses & deconstruction, debates against contracts of labor and the increasing dependence on credit all led to the eventual demiste of the Reconstruction era.
3) <em><u>Non-effective Law Enforcement practices. </u></em>It was a period of violence given the lack of effectiveness in the LE field to control the racial violence and the revolts from the people.
4) <em><u>Decline in national interest. </u></em>The nation was ready to leave behind the uncertainty and questions that plagued their everyday lives involving the Civil War. They sought to return to a normal life - to normalcy. This affected the support they could have given to all of the Reconstruction efforts.
