Warren is a town in Bristol County, Rhode Island. The population was 10,611 at the 2010 census.
Warren was the site of the Pokanoket Indian settlement of Sowams located on a peninsula within the Pokanoket region. The region consisted of over 60 settlements under the authority of Chief Massasoit (sometimes called Osamequin) who controlled the land from Plymouth to the eastern shores of Narragansett Bay. English colonists Edward Winslow and Stephen Hopkins from Plymouth Colony first visited there in July, 1621. Winslow and John Hampden saved Massasoit's life two years later and gained an important ally and lifelong friend. The colonists set up a trading post by 1632 on the banks of the Kickamuit River where they traded English goods for furs and other items. Roger Williams was banished from Salem, Massachusetts, in January, 1636, and fled to Sowams, becoming ill on the way. He was sheltered by Massasoit in Sowams until he recovered over the winter months; he later established Providence Plantations.
Permanent English settlement began east of the Indian village starting in 1653.
