Answer: Reconstruction
Explanation:
Reconstruction, in U.S. history, the period (1865–77) that followed the American Civil War and during which attempts were made to redress the inequities of slavery and its political, social, and economic legacy and to solve the problems arising from the readmission to the Union of the 11 states.
There is a great possibility that the end result of the war was different. For the entry of the United States into the war for victory was providential. If the United States had not entered, perhaps we would live in a different world now, if we consider the importance of the American entry into the war and all of its power in helping its allies to win.
