Abstract How did the rise of nationalism affect patterns of interstate wars? The conventional wisdom in mainstream security studies tends to treat the rise of nationalism as a ‘force amplifier’ that allowed states to wage war on an unprecedented scale, leading to deadlier—and, consequently, less frequent—wars. By building on emerging interdisciplinary research on territory and territoriality, this essay suggests that there was a second mechanism—complementary to the ‘force amplifier’ logic—through which the rise of nationalism affected the patterns of interstate war: nationalism changed the ‘character’ of territories in the modern state system, which, in turn, transformed state preferences over their territorial belongings. Before the rise of nationalism, state elites viewed their territories more as ‘divisible’ goods, which created strong incentives for states to wage frequent yet limited wars. The rise of nationalism, in this context, rendered territory controlled by a state more of an ‘inviolable homeland’, which then contributed to the increasing severity and decreasing frequency of interstate wars. The arguments presented in this essay have implications for not only the study of nationalism and war, but also bargaining models of war and the so-called ‘border fixity’ norm.
