The compelling question “Can peace lead to war?” offers students an opportunity to explore the historic controversy surrounding the extent to which the Treaty of Versailles caused World War II. Students consider not only the stipulations of the peace treaty but also the nature of historical interpretation by following the voices of historians throughout the inquiry. While progressing through the inquiry, students consider the original vision of the Treaty of Versailles, the conditions of the treaty itself, and the reactions to the treaty both at the time and by modern-day historians.
