Why did Marshall have such a lasting effect on the judicial system?

Chief Justice John Marshall had a profound and lasting impact on the American judicial system through his establishment of the principle of judicial review, most notably in the landmark case Marbury v. Madison. He reinforced the role of the Supreme Court as a co-equal branch of government, emphasizing the importance of federal law over state law. His decisions helped shape the interpretation of the Constitution, promoting a strong central government and protecting individual rights. Marshall's legacy endures in the way his rulings continue to influence legal precedents and the balance of power within the U.S. government.
