Explanation:

The reconstruction of the United States was the period following the civil war and was aimed at the return of the Confederate states to the union, the political, economic and social reconstruction of the southern states and the integration of the jailed soldiers into American society. It was a time of extreme change within American culture and it rekindled many political discussions and control strategies among political parties.
