In this book, David Komline explains how a broad and distinctly American religious consensus emerged in the first half of the nineteenth century, allowing people from across the religious spectrum to cooperate in systematizing and professionalizing America's schools in an effort to Christianize the country. At the height of this movement, several states introduced state-sponsored teacher training colleges and concentrated government oversight of schools in offices such as the one held by Mann. Shortly thereafter, the religious consensus that had served as the foundation for this common school system disintegrated. But the system itself remained, the legacy of not just one man, but of a whole network of reformers who put into motion a transatlantic and transdenominational religious movement - the "Common School Awakening."
