A Puritan of 16th and 17th-century England was an associate of any number of religious groups advocating for more purity of worship and doctrine, as well as personal and group piety.

They advocated separation from other Christian sects, which they viewed as having become corrupt
Under the reign of Charles I, many Puritans were persecuted so heavily that they left England for the New World, founding the Massachusetts Bay colony that would become Boston.
