What is considered the supreme law of the land?

The Constitution is considered the supreme law of the land because it establishes the fundamental framework for the government of the United States and outlines the rights and responsibilities of both the government and the citizens. Under the Supremacy Clause, found in Article VI of the Constitution, it is explicitly stated that the Constitution, along with federal laws made pursuant to it and treaties made under its authority, holds dominance over state laws and constitutions. This principle ensures that federal law prevails when there is a conflict between state and federal legislative measures, thereby maintaining a uniform system of governance across the nation. The authority of the Constitution serves as the foundation for all legal interpretations and governs how laws are made, enforced, and adjudicated in the United States.
