Write a one sentence summary of the central dispute in the case of mcculloch. v. maryland identify the key individuals and institutions involved in this case

McCulloch v. Maryland represented a power struggle between the State and Federal law. It was a landmark decision by the Supreme Court of the United States. The state of Maryland had attempted to impede operation of a branch of the Second Bank of the United States by imposing a tax on all notes of banks not chartered in Maryland. Though the law, by its language, was generally applicable to all banks not chartered in Maryland, the Second Bank of the United States was the only out-of-state bank then existing in Maryland, and the law was recognized in the court's opinion as having specifically targeted the U. S. Bank.
