In Piecing Together the Peaces, Alexander K. Antony and William R. Thompson provide a novel explanation for how peace took hold in the international system and why state behavior drastically changed. According to the standard line of reasoning, states need only democratize, liberalize their trade, modernize their economic culture, or choose to forego territorial pursuits to reach peace with another state. A bold challenge to the conventional wisdom that dominates interstate peace research, Antony and Thompson make the case that industrialization provides the starting point from which we can begin to unpack the transformation in conflict propensities among certain states.
