Answer: Reconstruction period (1865 - 1877).
Explanation:
The period of reconstruction in American history occurred after the American Civil War. During those 12 years, the government sought to address the country's accumulated problems that arose as a war product. Also, one of the elementary details of the reconstruction period is an effort to resolve slavery in the country. The Reconstruction period also represents a change in the elements of the American constitution, primarily involving the inclusion of new laws that were supposed to guarantee the civil rights of African Americans and Africans in the country. In this context, it is important to mention Amendment 13 of the United States Constitution, which abolishes slavery.
The Reconstruction period included the inclusion of the Confederation in the union and the regulation of all economic and political problems. The issue of economics was also one of the main problems. Namely, in the war, the south of the country was destroyed, and the cotton plantations where slaves used to work remained empty. So the economic problems were obvious. The south of the country, therefore, needed to be involved in industrial flows.
