The Great Puritan Migration to New England changed the course of American history. Between 1630 and 1640, more than 20,000 settlers crossed the Atlantic and reshaped New England forever. This 39-minute documentary posted by Discover America on November 30, 2025, explores why they fled England, how they built Boston, the rise of Puritan power, the clash with Indigenous nations, and how their beliefs still influence America today. This deep-dive reveals how one decade of migration transformed the New World and built the foundations of modern America.

King Charles I and William Laud shaped the conditions in England that led to the Puritan emigration to the New World to escape religious persecution.

Challenges to the authority of the Church of England inspired 42-year-old merchant and Puritan John Winthrop to lead a group of over 1,000 people to America in 1630 in what has been called “The Great Migration” to escape the religious intolerance of King Charles I.

Two thousand Puritans arrived in 1631 and 3,000 arrived in 1632, so by 1635 the total population exceeded 11,000. But, in 1640, the great migration ended as suddenly as it began, leaving a total population of 20,000 settlers in New England.
