Thor's hammer: How warfare enables and disables nation formation.

Scholars have neglected at a theoretical level the structuring role of warfare in the rise of nations and states. I argue that war‐making has been a constitutive force in the emergence and persistence of many national identities in four ways. First, wars can act as ‘turning points’ for good or ill to become national <italic>mythomoteurs</italic>. Second, they can create enduring popular we–they stereotypes against significant others. Third, they can generate a gemeinschaft of national sacrifice that anchors the nation after a return to peace. Finally, the outcomes of wars can legitimate ruling establishments or mobilise peoples against them. However, warfare can also disable nation formation. I shall focus on the impact of imperial wars on Eurasian borderland populations. While generating nationalism in these regions, such wars create shatter zones, marked by ethnic diversity and conflict that frustrate the formation of stable national communities.
