Colonial Massachusetts (1620–1691: Plymouth & Massachusetts Bay) was overwhelmingly settled by English Puritans—a religious movement seeking to "purify" the Church of England from within, who became separatists when reform failed.
Labor was a calling. Idleness was sin. This "Protestant work ethic" drove agricultural improvement, craft specialization, and maritime trade.
1647 Old Deluder Satan Act: towns ≥50 families = elementary school; ≥100 = grammar school. Harvard founded 1636. Literacy for Bible reading.
By 1691 (new charter), Massachusetts included:
• Non-Puritan Anglicans, Baptists, Quakers
• Enslaved Africans (~1,000 by 1700) and Indigenous people
• Maine district, Plymouth Colony merged
• Royal governor appointed — theocracy eroding
Puritan imprint: town meeting, public education, contractual government, moral exceptionalism, literary tradition (Bradstreet, Taylor, Mather). Not monolithic—debated grace, liberty, and authority from day one.
