Continuing conflict between Hamilton and Jefferson, especially over foreign policy, led to the formation of the Federalist and Republican parties. Although Washington remained aloof and warned against political parties in his farewell address, he generally supported Hamilton and Hamiltonian programs over those of Jefferson. The Democratic-Republican Party dominated the Upper South, Western frontier, and in parts of the middle states. Federalist support was concentrated in the major Northern cities and South Carolina. After his death in 1799 Washington became a symbolic hero of the Federalists.
