The Marshall Court established several key precedents that strengthened the federal government and judicial branch. Through cases like Marbury v. Madison, McCulloch v. Maryland, and Gibbons v. Ogden, the Court asserted the power of judicial review and national supremacy over the states in areas like interstate commerce and the national bank. The Court also began defining the relationship between Native American tribes and the federal government through cases like Cherokee Nation v. Georgia and Worcester v. Georgia.
