Territory is a persistent concern in international politics but is unevenly explored in the terrorism literature. We argue that territory has salience for terrorist actors and apply our argument to Rapoport’s influential “four waves” thesis of the modern history of terrorism. By examining the key ideologies and groups associated with each historical era, we find that territory was a crucial element to each wave even when it took on different forms. We conclude by calling for additional concern for territory in terrorism studies, which promises to yield new insights into pressing questions.
