The Declaration of Independence is primarily a  reaffirmation of the sovereignty of the colonists over the territories of the Thirteen Colonies.

Explanation:

The Declaration of Independence of the United States, drafted by Thomas Jefferson and ratified by the Second Continental Congress on July 4, 1776 in Philadelphia, approximately one year after the start of the American Revolutionary War, not only declared the independence of the Thirteen Colonies from the United Kingdom. This document, in turn, reaffirmed the sovereignty of the colonists over the American territories, establishing that it was them and not the Crown the one that would decide the destinies of America.
