Permanent English settlement began east of the Indian village starting in 1653. Massasoit and his oldest son Wamsutta sold to 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.
