John Sullivan was born in nearby Somersworth, and studied law. He settled in Durham to practice law in 1763, and purchased this house in 1763. It served as his home for the rest of his life, and is buried in the family cemetery nearby. Sullivan was a vocal opponent of British rule in the colonies, and was elected to the First Continental Congress in 1774. In December of that year he led a raid on Fort William and Mary in which the colonial militia seized munitions stored there. He was appointed a brigadier general in the Continental Army in 1775, and served through the American Revolutionary War. He participated in the Siege of Boston, and was captured by the British in the 1776 Battle of Long Island. After being exchanged, he served in the Battle of Trenton, the Philadelphia campaign of 1777, the failed attempt to recapture Newport, Rhode Island, and the 1779 Sullivan Expedition, in which the Iroquois, who had largely sided with the British, were driven from upstate New York. Sullivan's actions and barbed personality made him enemies in Congress, and he resigned from the army late in 1779. He returned to New Hampshire, where he served as Attorney General 1782-86, and as President (the office now known as Governor) 1787-89. He chaired the state convention that ratified the United States Constitution.
