What caused the loyalty of John winthrop and other Puritans in the Great Migration?

First, the pursuit of religious freedom in the concept of religious freedom is an important reason for the British Puritans to emigrate overseas. During the period of 65438-1930s, King Henry VIII of England launched a top-down religious reform movement in England in order to strengthen the kingship and get rid of the oppression of the Pope and the church. However, this reform movement is not thorough. Henry VIII claimed to be the head of the church, practiced the unity of politics and religion, and established the Anglican Church as the Anglican Church. Although Anriganism belongs to Protestantism, its teachings retain many remnants of Roman Catholicism. The idea of eliminating the residual Catholic elements in the state religion and carrying out a thorough religious reform came into being, hence the name Puritanism, and those who adhere to Puritanism are called Puritans. Most Puritans opposed the bishop system and hierarchy, and demanded democratization within the church organization, religious tolerance and freedom of belief, simplified religious ceremonies and the establishment of a truly pure church. The opinions and demands of the Puritans were strongly opposed by the King of England and the Church of England, regarded as "heresy", and a large number of Puritans were severely attacked and persecuted and forced into exile. 1620, the "ancestor immigrants" of the Puritans arrived in Plymouth Bay by may flower, which marked the beginning of the British Puritans' creation of "New Canaan" in the New England Colony in North America. 1630, John F. winthrop and others led more than 1,000 English Puritans to Massachusetts Bay with the great dream of building a "city on the top of a mountain" in North America, which started the Puritans' immigration wave.
