The Puritans were English Protestants in the 16th-17th centuries who sought to "purify" the Church of England and believed the Church had not gone far enough in reforming its doctrines, liturgy, and structure. Many Puritans immigrated to America for religious freedom, seeking to establish a religious community aligned with their beliefs. The Puritans who settled in Plymouth were mostly Separatists who broke from the Church of England, while those in Boston wanted to reform the Church of England from within. Their beliefs, including a focus on biblical literalism, predestination, and the Protestant work ethic, profoundly influenced early American society and culture.
