In the 1830s, the population of Ohio was much more diverse than was that of Massachusetts. For the most part, school reformers in both states came from a white, Protestant, English-speaking majority and did little to look beyond their narrow cultural horizons when advocating educational change. In Ohio, however, groups that fell outside of this majority were larger and could more feasibly, although not always successfully, engage the debate about school reform. This chapter highlights the way three such groups, African Americans, Germans, and Catholics, interacted with the Common School Awakening, illustrating how their objections to the key assumptions of the awakening adumbrated larger weaknesses that would eventually undermine this educational reform movement.
