Warren is a town in Bristol County, Rhode Island. The population was 10,611 at the 2010 census.
Warren was the site of the Indian village of Sowams, located on the peninsula called Pokanoket (Mount Hope Neck), and Edward Winslow and Stephen Hopkins from the Plymouth Colony established a trading post there in 1621. In 1623, Winslow and John Hampden saved the life of Wampanoag Sachem Massasoit, gaining an important ally. In 1636, Roger Williams was banished from Salem, Massachusetts and fled to Sowams, where he was sheltered by Massasoit until he established Providence Plantations.
Permanent English settlement began east of the Indian village starting in 1653. Massasoit and his oldest son sold to certain Plymouth Colony settlers what is now Warren and parts of Barrington, Rhode Island, Swansea, Massachusetts, and Rehoboth, Massachusetts. The land was part of the Massachusetts Bay Colony and was first incorporated as part of Swansea. After the death of Massasoit, however, relations became strained between the Indians and the settlers, leading to King Philip's War in 1675 when the Indians destroyed the settlement at Sowams. In 1668, the township was officially incorporated with the name Sowams; in 1691, the Plymouth Colony merged with the Massachusetts Bay Colony.
