Puritans immigrated to America in the 1600s to escape religious persecution in England. They settled in Massachusetts with the goal of creating a theocratic society where they could freely worship God. Puritanism emphasized hard work, discipline, and aiming for moral perfection to please God. They established Harvard University and schools to educate followers. Though Puritanism declined by 1750, it greatly influenced American culture by stressing the importance of education, hard work, and the idea that God rewards righteousness.
