The idea that Federalist political strength was concentrated along the Atlantic seaboard is a historical oversimplification. Federalism—as a system dividing power between central and regional governments—is a constitutional structure, not a geographic phenomenon. In the early United States, Federalist support existed in commercial centers across regions, including New England, the Mid-Atlantic, and even parts of the South and West. Party alignment depended more on economic interests, urbanization, and views on centralized authority than on proximity to the coast.
