Final answer:
The Marshall Court is considered a Federalist legacy because its rulings expanded federal powers.
Step-by-step explanation:
Historians think that the Marshall Court constituted a Federalist legacy because its rulings expanded federal powers. Chief Justice John Marshall and the associate justices issued a series of decisions strengthening the role of the federal government, particularly in cases like Marbury v. Madison and Fletcher v. Peck.
These decisions asserted the authority of the federal government over constitutional matters at both the federal and state levels, which aligned with the Federalist party's belief in a strong central government.
