of the original colonists, since many returned to England shortly after arriving on the continent, but it produced more than 16 million descendants. This so-called "Great Migration" is not so named because of sheer numbers, which were much less than the number of English citizens who immigrated to Virginia and the Caribbean during this time. The rapid growth of the New England colonies (around 700,000 by 1790) was almost entirely due to the high birth rate and lower death rate per year. Puritan hegemony lasted for at least a century. That century can be broken down into three parts: the generation of John Cotton and Richard Mather, 1630–62 from the founding to the Restoration, years of virtual independence and nearly autonomous development; the generation of Increase Mather, 1662–89 from the Restoration and the Halfway Covenant to the Glorious Revolution, years of struggle with the British crown; and the generation of Cotton Mather, 1689–1728 from the overthrow of Edmund Andros (in which Cotton Mather played a part) and the new charter, mediated by Increase Mather, to the death of Cotton Mather. The Puritans in the Colonies were great believers in education. They wanted their children to be able to read the Bible themselves, and interpret it themselves, rather than have to have a clergyman tell them what it says and means. In 1635, they established the Boston Latin School to educate their sons, the first and oldest formal education institution in the English speaking New World. They also set up what were called dame schools for their daughters, and in other cases taught their daughters at home how to read. As a result, Puritans were among the most literate societies in the world. By the time of the American Revolution there were 40 newspapers in the United States (at a time when there were only two cities—New York and Philadelphia—with as many as 20,000 people in them). The Puritans also set up a college (Harvard University) only six years after arriving in Boston.

While Puritans did not agree on all doctrinal points, most shared similar views on the nature of God, human sinfulness, and the relationship between God and mankind. They believed that all of their beliefs should be based on the Bible, which they considered to be divinely inspired. The concept
