Puritans were generally members of the Church of England who believed that the Church of England was insufficiently reformed, retaining too much of its Roman Catholic doctrinal roots, and who therefore opposed royal ecclesiastical policy under Elizabeth I of England, James I of England, and Charles I of England . Most Puritans were "non-separating Puritans", meaning that they did not advocate setting up separate congregations distinct from the Church of England; a small minority of Puritans were "separating Puritans" who advocated setting up congregations outside the Church . The Pilgrims were a Separatist group, and they established the Plymouth Colony in 1620 . Non-separating Puritans played leading roles in establishing the Massachusetts Bay Colony in 1629, the Saybrook Colony in 1635, the Connecticut Colony in 1636, and the New Haven Colony in 1638 . The Colony of Rhode Island and Providence Plantations was established by settlers expelled from the Massachusetts Bay Colony because of their unorthodox religious opinions . Puritans were also active in New Hampshire before it became a crown colony in 1691 . </P> <P> Most Puritans who migrated to North America came in the decade 1630 - 1640 in what is known as the Great Migration . See the main articles on each of the colonies for information on their political and social history; this article focuses on the religious history of the Puritans in North America . </P>
