why did the puritans leave england

The Puritans left England primarily because they were dissatisfied and persecuted for their religious beliefs. They sought to purify the Church of England, which they felt was still too Catholic in its rituals and governance. The English crown, which was head of both the church and state, enforced conformity to the Church of England, and Puritans faced severe punishments for their dissent. Seeking religious freedom and a place to practice their faith without persecution, many Puritans emigrated to America starting in 1630, hoping to establish a society based on their religious principles. This migration was both a response to religious oppression and an aspiration for a new community where they could live according to their Calvinist beliefs.
