Waltham was created on October 31, 1796 (Vermont Act of Incorporation) and never had a charter of its own, instead coming about through an unusual set of circumstances.
When Vergennes was incorporated out of parts of New Haven, Ferrisburgh and Panton, it was given only the 1,200 acres it now contains. In 1791 about three square miles were taken from New Haven and given to Vergennes, but in 1796 the extra acreage was taken away from Vergennes and incorporated into what is now the town of Waltham.
