Define Supremacy Clause?

Answer 1

Article VI, Paragraph 2 of the United States Constitution is known as the Supremacy Clause:

"This Constitution, and the laws of the United States which shall be made in Pursuance thereof; and all Treaties made, or which shall be made, under the authority of the United States, shall be Supreme Law of the land; and the Judges in every state shall be bound thereby, any thing in the Constitution or Laws of any state to the contrary notwithstanding."

The Supremacy Clause establishes the Constitution, Federal Statutes, and U.S. treaties as "the supreme law of the land." The Constitution is the highest form of law in the American legal system. State judges are required to uphold it, even if state laws or Constitutions conflict with it.

Answer 2

Supremacy clause means that an entity is more powerful than another. For example, civilian authority has supremacy over the military which means that the people through the President has control over the military instead of the latter having power over the civilians.
