In 1870, just five years after the civil war, americans measured for the first time illiteracy rates and found the figure of just 20%, while in Brazil, for instance, we had over 90% by that same time. This book helps to explain in part why America had acomplished that. As it reports, it was a consequence of serious concerns with creating a society able to make succeed the project of a democratic republic. Since the founding fathers, american society realized that education was key to the success of a democracy, and this book presents an interesting description of the common school movement, which was responsible for the widespread of primary education during the antebellum period.
