The Declaration of Independence and The Preamble of the Constitution

The Declaration of Independence is exactly what it says it is, but the Constitution is not. In the Declaration of Independence the United States, states that the thirteen colonies is now separated from Great Britain. And in The Preamble to the Constitution the United States claims the rights and laws its own people will abide by in the newly free land. Although they are both, in a lot of ways, just lists, they are focused on different aspects of the freedom. One is the reasoning for why they're separating themselves and the other is that now that they're free they'll need some ground rules so it doesn't become an anarchy.
