罗德岛由罗杰·威廉姆斯于1636年创立。最初由阿德里安·布洛克（Adrian Block）称为“Roodt Eylandt”，他曾为荷兰探索过该地区，由于他在那里发现了红土，这个名字的意思是“红岛”。罗杰·威廉姆斯在英格兰长大，1630年与他的妻子玛丽·巴纳德一起离开，当时清教徒和分离主义者的迫害开始增加。他搬到了马萨诸塞湾殖民地，并在1631年至1635年间担任牧师和农民。然而，殖民地的许多人认为他的观点非常激进。然而，他认为他所实践的宗教不受英格兰教会和英国国王的任何影响是非常重要的。此外，他甚至质疑国王有权向新世界的个人提供土地。在担任塞勒姆牧师期间，他与殖民领导人进行了重大斗争。他觉得每个教会会众都应该是自治的，不会遵循领导人的指示。 1635年，威廉姆斯被马萨诸塞湾殖民地驱逐到英格兰，因为他信仰分离教会和国家以及宗教自由。他逃离并与Narragansett印第安人一起生活在普罗维登斯。普罗维登斯于1636年成立，吸引了其他分离主义者，他们希望逃离他们不同意的殖民宗教规则。其中一位分离主义者是安妮哈钦森。她也因在马萨诸塞湾对教堂发表讲话而被放逐。她搬到了该地区，但没有在普罗维登斯定居。相反，她帮助组建了朴茨茅斯。随着时间的推移，定居点继续增长。另外两个定居点出现了，所有四个定居点都加在了一起。 1643年，威廉姆斯前往英格兰并获准从普罗维登斯，朴茨茅斯和纽波特组建普罗维登斯种植园。后来改为罗德岛。从1654年到1657年，威廉姆斯将继续担任罗德岛政府的总统大会。罗德岛是美国革命时期繁荣的殖民地，拥有肥沃的土壤和充足的港口。然而，它的港口也意味着在法国和印度战争之后，罗德岛受到英国进出口法规和税收的严重影响。殖民地是独立运动的领跑者。它在独立宣言之前切断了关系。虽然在罗德岛土地上没有发生过很多实际的战斗，但直到1779年10月英国占领并占领纽波特。战争结束后，罗德岛继续表现出独立性。事实上，它不同意联邦党人批准美国宪法，只有在它生效后才这样做。
Rhode Island was founded in 1636 by Roger Williams. Originally called “Roodt Eylandt” by Adrian Block, who had explored that area for the Netherlands, the name means ‘red island’ due to the red clay that he found there. Roger Williams had grown up in England, only leaving in 1630 with his wife Mary Barnard when it the persecution of Puritans and Separatists began increasing. He moved to the Massachusetts Bay Colony and worked from 1631 to 1635 as a pastor and a farmer. However, many in the colony saw his views as quite radical. However, he felt it extremely important that the religion he practiced be free from any influence of the Church of England and the English king. In addition, he even questioned the right of the King to grant land to individuals in the New World. While serving as a pastor in Salem, he had a major fight with the colonial leaders. He felt that each church congregation should be autonomous and would not follow directions sent down from the leaders. In 1635, Williams was banished to England by the Massachusetts Bay Colony for his beliefs in separation of church and state and freedom of religion. He fled and lived with the Narragansett Indians in what would become Providence. Providence, formed in 1636, attracted other separatists who wished to flee from colonial religious rules of which they did not agree. One such separatist was Anne Hutchinson. She was also banished for speaking out against the Church in Massachusetts Bay. She moved to the area but did not settle in Providence. Instead, she helped formed Portsmouth. Over time, the settlements continued to grow. Two other settlements arose, and all four joined together. In 1643, Williams went to England and gained permission to form Providence Plantations from Providence, Portsmouth, and Newport. This was later changed to Rhode Island. Williams would continue to serve in the government of Rhode Island as president of its general assembly from 1654 to 1657. Rhode Island was a prosperous colony by the time of the American Revolution with its fertile soil and ample harbors. However, its harbors also meant that after the French and Indian War, Rhode Island was severely impacted by British import and export regulations and taxes. The colony was a frontrunner in the movement towards independence. It severed ties before the Declaration of Independence. Although not a lot of actual fighting occurred on Rhode Island soil, except for the British seizure and occupation of Newport until October 1779. After the war, Rhode Island continued to show its independence. In fact, it did not agree with the federalists in ratifying the U.S. Constitution and only did so once it had gone into effect.
