Newtown is a town in Fairfield County, Connecticut, United States. It is part of the greater Danbury metropolitan area as well as the New York metropolitan area. Newtown was founded in 1705 and later incorporated in 1711. As of the 2010 census, its population was 27,560. In 1705, English colonists purchased the Town site from the Pohtatuck Indians, a branch of the Pasgussett. It was originally known as Quanneapague. Settled by migrants from Stratford and incorporated in 1711, Newtown residents had many business and trading ties with the English. It was a stronghold of Tory sentiment during the early Revolutionary War. Late in the war, French General Rochambeau and his troops encamped here in 1781 during their celebrated march on their way to the siege of Yorktown, Virginia, which ended the Revolution.
