Benedict Arnold was president and then governor of the Colony of Rhode Island and Providence Plantations, serving for a total of 11 years in these roles. He was born and raised in the town of Ilchester, Somerset, England, likely attending school in Limington nearby. In 1635 at age 19, he accompanied his parents, siblings, and other family members on a voyage from England to New England where they first settled in Hingham in the Massachusetts Bay Colony. In less than a year, they moved to Providence Plantation at the head of the Narragansett Bay at the request of Roger Williams. In about 1638, they moved once again about five miles (8 km) south to the Pawtuxet River, settling on the north side at a place commonly called Pawtuxet. Here they had serious disputes with their neighbors, particularly Samuel Gorton, and they put themselves and their lands under the jurisdiction of Massachusetts, a situation which lasted for 16 years.

Roger Williams was an English-born New England Puritan minister, theologian, and author who founded Providence Plantations, which became the Colony of Rhode Island and Providence Plantations and later the State of Rhode Island. He was a staunch advocate for religious freedom, separation of church and state, and fair dealings with the Native Americans.
