Maryland had a significant impact on the understanding of the Constitution. Marbury v. Madison established the principle of judicial review, expanding the power of the courts, while McCulloch v. Maryland confirmed that the federal government had the authority to create a national bank.

Additionally, Maryland played a key role in ratifying the Constitution itself. The state held a convention in 1788 to debate and ultimately approve the document, becoming the seventh state to do so. Maryland's support was crucial in achieving the necessary nine states to officially establish the Constitution as the supreme law of the land.

Furthermore, Maryland's contributions to the constitutional understanding continued with the ratification of the Bill of Rights in 1789. The state was one of the first to ratify these ten amendments to the Constitution, which guarantee individual liberties and protections against government overreach. Maryland's early support of the Bill of Rights helped ensure its eventual adoption by all states, solidifying these essential rights for all Americans.

Overall, Maryland's role in shaping the understanding and interpretation of the Constitution has been significant and enduring. From the establishment of judicial review to the ratification of the Bill of Rights, the state has played a crucial part in defining the scope and limits of government power in the United States.
