What was the significance of McCulloch v. Maryland?

The significance of McCulloch v. Maryland lies in its affirmation of the supremacy of federal law over state law. This landmark case clarified the relationship between state and federal authorities, particularly in the context of implied powers granted to the federal government. The ruling emphasized that states do not possess the authority to tax or otherwise impede legitimate federal operations. This established a precedent for the idea that federal institutions operate under a higher legal status than state laws, which has played a vital role in shaping the balance of power in the U.S. federal system. The ruling further reinforced the concept that the federal government can exercise powers beyond those explicitly enumerated in the Constitution, as long as they are in pursuit of its legitimate ends, which was a significant move to enhance federal authority.
