What is the supreme law of the land?

The Constitution is known as the supreme law of the land because it establishes the fundamental principles and framework of the government of the United States. It serves as the highest legal authority in the country, meaning that all laws made by Congress and state legislatures must comply with the Constitution. If there are any conflicts between state laws and the Constitution, the Constitution prevails.

The Bill of Rights, while crucial, is a component of the Constitution that outlines specific rights and freedoms guaranteed to individuals. The Declaration of Independence is a historic document proclaiming the colonies' separation from British rule, but it does not establish the governance of the country. The Articles of Confederation were the first governing document for the United States but were ultimately replaced by the Constitution due to their weaknesses. Thus, the Constitution holds the ultimate authority in determining the laws and structure of the U.S. government.
