Narragansett people
In the 17th century, when English settlers arrived, southeastern Connecticut was the scene of rivalry between the Pequot people, the dominant Native American group in the New London area, and the newly independent Mohegan. The latter became friendly to the English. For defense against the Pequot, the Mohegan sachem Uncas had established a fortified village on a promontory above the Thames River within what is now the town of Montville. The Mohegan village, now known as Fort Shantok, was protected on the inland side by palisades first built in about 1636 at the time of the Pequot War, rebuilt during wars with the Narragansett people circa 1653–1657, and rebuilt again at the time of King Philip's War (1675–1676).
