In 1772 his family relocated to Newfane, Vermont, a new settlement which at the time contained fewer than 20 families, and he was soon appointed a justice of the peace. He was chosen as Newfane's first town clerk when the town was organized in 1774, and he served from 1774 to 1783, and again from 1784 to 1789.
Knowlton had been a Loyalist in the years leading up to the American Revolution, and had received from the British government a land grant in Sherbrooke, Quebec, but upon moving to Vermont he aligned himself with the Patriot cause. In 1782, the Continental Congress authorized the arrest of Knowlton and Samuel Wells of Brattleboro after they came under suspicion of communicating with the British government in Canada and New York City. Knowlton fled to Canada, but he returned to Newfane a year later. During Vermont's early years, the colonial governments of New Hampshire and New York disputed jurisdiction over Vermont, including the right to sell land grants. Vermont formed its own government, which recognized land titles previously purchased from New Hampshire. After the Revolution, Vermont's independent government worked to obtain statehood, while New York attempted to exert control over Vermont. Knowlton was sent to the Congress of the Confederation as an emissary of Vermont residents who held New York land grants, but became a convert to the cause of Vermont statehood.
Post-Revolution
In 1784, Knowlton was again accused of being sympathetic to the British in Canada, and southeastern Vermonters loyal to New York, led by Francis Prouty, took him from his home by force in the middle of the night, and released him in Massachusetts. He returned to Newfane just as a detachment of militia led by Stephen R. Bradley was preparing to pursue his abductors and free him. Prouty evaded capture for several months, and was eventually apprehended at his home. He was indicted for burglary, forcibly carrying Knowlton away from his home, and resisting arrest. He was acquitted of the first two charges, and received a fine and a 40-day jail sentence on the charge of resisting arrest. As a condition of Vermont's entry into the Union in 1791, Vermont paid New York $30,000 to settle claims by holders of land grants purchased from New York, and Knowlton received approximately $250 as compensation for the New York title to his Newfane land. Knowlton served in the Vermont House of Representatives in 1784, 1785, 1788, 1789, 1792, 1805, and 1806, and was a member of Vermont's Governor's Council from 1789 to 1800. In 1786 Knowlton was appointed a Justice of the Vermont Supreme Court, but his position was eliminated later that year when the size of the court was reduced. He served as Chief Judge of the Windham County Court from 1787 to 1793, and again from 1802 to 1803. In 1786 Knowlton was one of the recipients of land grants and the charter for the town of Danville. In 1791 Knowlton received from Vermont's government a 10,000 acre land grant in Franklin County as payment for his government service. He later sold this grant to Joseph Baker, who used it to found the town of Bakersfield.
