The American Civil War has been called the Second American Revolution because of the many changes it brought to American life. In as much detail as possible, describe these changes; they can be economic, legal, social, political, military, governmental, etc. The more different examples you come up with, the more points; for example, even the battles fought had an impact because of the changing way the battles were fought, the types of weapons used, and the changes those battles caused in the nation.
