How does the United States Constitution differ from the Declaration of Independence?

The Declaration of Independence, adopted on July 4, 1776, announced the separation of the 13 American colonies from Great Britain and articulated the philosophical basis for this separation, emphasizing natural rights and the consent of the governed. It served as a statement of intent and justification for revolution.12

In contrast, the U.S. Constitution, drafted in 1787, is the fundamental law of the U.S. federal government. It establishes the structure of government, outlines the powers of its branches (legislative, executive, and judicial), and defines the basic rights of citizens. While the Declaration proclaimed ideals, the Constitution created the framework for a functioning nation based on those ideals, influenced by thinkers like John Locke.3456
