Answer:
It gave the federal government more power over the states.
Step-by-step explanation:
During the period that Chief Justice Marshall was at the US Supreme Court the power of the federal government rose visibly. He decided in the ruling McCulloch v. Maryland that the state of Maryland did not have the power to pass taxes on the National Bank because the US Congress had the power to create the National Bank. The same decision reinforced the Supremacy Clause.
Also, in another decision, Gibbons v. Ogden, the Court decided that the US Congress had the power to regulate interstate commerce, included navigation, which also reinforced the Supremacy Clause.
