The root cause of the American Civil War is perhaps the most controversial topic in American history. Even before the war was over, scholars in the North and South began to analyze and interpret the reasons behind the bloodshed.
The scholars immediately disagreed over the causes of the war and disagreement persists today. Many maintain that the primary cause of the war was the Southern states’ desire to preserve the institution of slavery. Others minimize slavery and point to other factors, such as taxation or the principle of States' Rights.
In 2011, at the outset of the sesquicentennial, a Pew Research Center poll found that Americans were significantly divided on the issue, with 48% saying the war was "mainly about states' rights," 38% saying the war was "mainly about slavery," with the remainder answering "both equally" or "neither/don't know."
Article 2 of the Constitution describes the powers of the executive branch.
