what colony did roger williams establish

Roger Williams established the colony known as Providence Plantations in 1636, which later became part of the Colony of Rhode Island and Providence Plantations. He founded Providence after being exiled from the Massachusetts Bay Colony due to his religious and political beliefs. Williams purchased land from the Narragansett Indians and created a settlement that emphasized religious freedom and separation of church and state. This colony became a refuge for those persecuted for their beliefs, including Baptists, Quakers, and others. The settlements of Providence, Portsmouth, Newport, and Warwick eventually united under the Colony of Rhode Island and Providence Plantations
