Puritans, a sect, which professed to follow the pure word of God, in opposition to traditions, human constitutions, and other authorities. In the reign of Queen Elizabeth, part of the Protestants were desirous of introducing a simpler, and, as they considered it, a purer, form of church government and worship, than that established by law; from which circumstance, they were called Puritans. In process of time, this party increased in numbers, and openly broke off from the Church, laying aside the English liturgy, and adopting a service-book published at Geneva, by the disciples of Calvin. They were treated with great rigor by the Government, and many of them left the kingdom and settled in Holland. Finding themselves not so eligibly situated in that Country, as they had expected to be, a portion of them embarked for America, and were the first settlers of New England.
