The document summarizes the founding and growth of the Massachusetts Bay Colony by Puritans in the early 1600s. It details how John Smith surveyed the coasts of Massachusetts and Maine in 1614. Many Puritans fled religious persecution in England and settled in Holland but later moved to North America on the Mayflower in 1620, signing the Mayflower Compact which established a governing authority. The Massachusetts Bay Colony was founded in 1628, attracting over 20,000 migrants led by John Winthrop who envisioned the colony as a "city upon a hill" with God's favor and exceptional among others. The colony grew through additional settlements founded from Plymouth.
