How did society and American culture change after the civil war?

Explanation: The Civil War had a greater impact on American society and the polity than any other event in the country's history. It was also the most traumatic experience endured by any generation of Americans. At least 620,000 soldiers lost their lives in the war, 2 percent of the American population in 1861.
