Puritans were a group of English Protestants in the 16th and 17th centuries who sought to purify the Church of England of its Roman Catholic practices. They were heavily influenced by the teachings of John Calvin, a French theologian and reformer who developed the system of Christian theology known as Calvinism. Puritans embraced Calvinism and its emphasis on predestination, the idea that God has already determined who will be saved and who will be damned. They also adopted Calvin's strict moral code, which emphasized hard work, frugality, and piety.
