Preamble

Explanation:

The Preamble of the U.S. Constitution is a brief introduction of the Constitution that sets its fundamental purposes and guiding principles, in which are included the principles of democracy, popular sovereignty, justice, domestic tranquility, liberty, and America's general welfare. It states the following:

We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defense, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.

the historians cited in the article all agree with one another about the cause of the civil war. despite coming from different backgrounds and cultures, the historians agree that slavery was the root cause of the civil war. the fact that all these historiansgenerally agree with one another makes their shared viewpoints more reliable and valid, especially because the historians have different backgrounds and all work for the well-respected institutions of howard university, clemson university, and the university of colorado.
