Puritan migration to New England (1620–1640)

The Puritan migration to New England was marked in its effects in the two decades from 1620 to 1640, after which it declined sharply for a time. The term Great Migration usually refers to the migration in this period of English Puritans to Massachusetts and the West Indies, especially Barbados. They came in family groups rather than as isolated individuals and were motivated chiefly by a quest for freedom to practice their Puritan religion.

King James I of England made some efforts to reconcile the Puritan clergy in England, who had been alienated by the conservatism blocking reform in the Church of England. Puritans embraced Calvinism (Reformed theology) with its opposition to ritual and an emphasis on preaching, a growing sabbatarianism, and preference for a presbyterian system of church polity as opposed to the episcopal polity of the Church of England, which had also preserved medieval canon law almost intact. They opposed church practices that resembled Roman Catholic ritual.

This religious conflict worsened after Charles I became king in 1625, and Parliament increasingly opposed his authority. In 1629, Charles dissolved Parliament with no intention of summoning a new one, in an ill-fated attempt to neutralize his enemies there—which included numerous Puritans. With the religious and political climate so unpromising, many Puritans decided to leave the country. Some of the migration was also from the expatriate English communities in the Netherlands of nonconformists and Separatists who had set up churches there since the 1590s.

The Winthrop Fleet of 1630 included eleven ships led by the flagship Arbella; it delivered some 700 passengers to the Massachusetts Bay Colony. Migration continued until Parliament was reconvened in 1640, at which point the scale dropped off sharply. The English Civil War began in 1641, and some colonists returned from New England to England to fight on the Puritan side. Many then remained in England, since Oliver Cromwell backed Parliament as an Independent.
