In which case did the Supreme Court rule that federal law was stronger than state law concerning a national bank?

The Supreme Court ruling in McCulloch v. Maryland established the principle that federal law has supremacy over state law, particularly in matters concerning constitutional powers of the federal government. In this case, the Second Bank of the United States was created by Congress, and the state of Maryland attempted to impose a tax on the bank. The Court, led by Chief Justice John Marshall, determined that the Constitution allowed Congress to create a national bank and that Maryland's attempt to tax the bank was an unconstitutional interference with federal authority.

This ruling affirmed the constitutional doctrine of implied powers, indicating that the federal government could take actions not explicitly outlined in the Constitution if those actions were deemed necessary and proper to execute its powers. This decision reinforced the supremacy of federal legislation and further solidified the role of the federal government in relation to the states, marking a significant moment in the development of federalism in the United States.

Other cases, while significant, do not specifically address the relationship between federal laws and state attempts to regulate or tax federal entities in the same direct manner as McCulloch v. Maryland.
