Between 1628 and 1640 perhaps 20,000 Puritans would leave England and settle in Boston and environs. Then English immigration to Massachusetts would stop as abruptly as it started. The Puritans of Massachusetts would thrive with only trivial incremental immigration for the next 200 years, creating a uniquely American society in New England, a homogeneous world with its own culture and polity that would eventually become the beating heart of the American Revolution. In this episode and the next, we talk about the theological and political forces that set the stage for the Puritan Great Migration, and the new articulation of English political liberty during the crucial second and third decades of the 17th century that arose from conflict over the scope of royal power between Sir Edward Coke and King James I. Errata: A listener pointed out that Luther posted 95 theses, rather than the 99 I somehow said and sadly missed in post-production. Must have been thinking of red balloons.
