Puritanism was a religious movement that emerged in the 16th and 17th centuries in England. Puritans believed in strict adherence to the Bible and sought to purify the Church of England from what they saw as corrupt practices. They emphasized the importance of personal piety, hard work, and moral discipline. Puritans were known for their strict moral code and opposition to luxury and excess. They played a significant role in the colonization of America, particularly in New England, where their influence can still be seen today in the region's culture and values.
