Book excerpt: The Trial of Anne Hutchinson re-creates one of the most tumultuous and significant episodes in early American history: the struggle between the followers and allies of John Winthrop, governor of the Massachusetts Bay Colony, and those of Anne Hutchinson, a strong-willed and brilliant religious dissenter. The controversy pushed Massachusetts to the brink of collapse and spurred a significant exodus. The Puritans who founded Massachusetts were poised between the Middle Ages and the modern world, and in many ways, they helped to bring the modern world into being. The Trial of Anne Hutchinson plunges participants into a religious world that will be unfamiliar to many of them. Yet the Puritans' passionate struggles over how far they could tolerate a diversity of religious opinions in a colony committed to religious unity were part of a larger historical process that led to religious freedom and the modern concept of separation of church and state. Their vehement commitment to their liberties and fears about the many threats these faced were passed down to the American Revolution and beyond.
