In the U.S. context, "federalist" refers to a political ideology advocating for a system of government where power is divided between a central authority and state governments. This principle was foundational to the drafting of the U.S. Constitution, reflecting a compromise between supporters of a strong central government and those favoring state sovereignty. Federalists promoted the idea that a strong national government was essential for maintaining order and security, while still allowing states to retain significant powers. The Federalist Papers are key documents that elucidated these principles.
