Unlike the original 13 states, Vermont was never a British colony. Its path to statehood was entirely distinct:
Between 1749–1764, New Hampshire Governor Benning Wentworth issued ~130 land grants west of the Connecticut River—territory also claimed by New York. New York contested them, leading to legal battles and sporadic violence (Ethan Allen's Green Mountain Boys resisted NY authority).
New York dropped claims in 1790 after Vermont paid $30,000 compensation. Vermont ratified U.S. Constitution January 1791; admitted March 4, 1791.
Vermont's non-colonial origin fostered a strong independent streak—evident in its town-meeting governance, early abolitionism, and enduring political uniqueness (only state never to send a Republican to Congress until 1854; first to legalize civil unions, 2000).
