What concept is established in the Supremacy Clause?

The Supremacy Clause, found in Article VI, Clause 2 of the United States Constitution, establishes that federal law takes precedence over state laws and constitutions. This means that when there is a conflict between federal law and state law, federal law will prevail. This principle is crucial for maintaining a cohesive legal framework across the country, ensuring that the federal government can enact and enforce laws uniformly regardless of state legislation.

The importance of this clause lies in its role in preventing individual states from enacting laws that would contradict or undermine federal laws or the Constitution itself. It helps create a legal hierarchy where states cannot create laws that would contravene federal authority, promoting national unity and consistency in governance.
