What is the supreme law of the land?

The Constitution is regarded as the supreme law of the land because it establishes the fundamental principles and framework of the United States government. It is the foundation upon which all laws and government actions are based, providing guidelines for the operation of the federal and state governments. The Constitution outlines the powers of government, enumerates the rights of citizens, and serves as the highest legal authority in the country. Any laws or actions taken by the government must adhere to the principles set forth in the Constitution; otherwise, they can be challenged in court.

The other options—such as the Bill of Rights, which comprises the first ten amendments to the Constitution and focuses specifically on the rights of individuals; the Declaration of Independence, which proclaims the colonies' independence from British rule but does not establish a government; and the Articles of Confederation, which were the first governing document of the United States but were ultimately deemed ineffective—are important documents in American history. However, they do not hold the same legal authority as the Constitution, which clearly defines itself as the supreme law.
