Which document serves as the supreme law of the land in the United States?

The Constitution serves as the supreme law of the land in the United States. It was established to create the framework for the federal government and delineates the rights and responsibilities of the government and its citizens. The supremacy clause of the Constitution, found in Article VI, asserts that the Constitution and federal laws made pursuant to it take precedence over state laws. This foundational document establishes the principles of democracy, separation of powers, and checks and balances within the government.

In contrast, while the Articles of Confederation were an early attempt to govern the United States following independence, they were ultimately deemed ineffective due to their lack of a strong central authority. The Bill of Rights, which comprises the first ten amendments to the Constitution, specifically outlines individual rights and protections but does not serve as the overarching legal framework for the country. The Declaration of Independence, although a significant historical document that declared the colonies' intent to separate from British rule, does not function as a governing document or law within the legal system of the United States.
