The Four Waves Of English Speaking Immigration To America from 1629 to 1775
During the very long period from 1629 to 1775, the present area of the United State was settled by at least four large waves of English-speaking immigrants. The first was an exodus of Puritans from the east of England to Massachusetts during a period of eleven years from 1629 to 1640. The second was the migration of a small Royalist elite and large numbers of indentured servants from the south of England to Virginia (ca. 1632-75). The fourth was a flow of English-speaking people from the borders of North Britain and northern Ireland to the Appalachian backcountry mostly during the half-century from 1718 to 1775.
