Are states more interested in claiming territories that have economic resources? While previous theories of international relations assume that resources make a territory more tempting to claim, all else equal, I argue that certain types of economic resources can make states less willing to claim a territory. The presence of capital-intensive resources—such as oil or minerals—raises concerns about how the benefits of acquiring the territory would be distributed within the nation. These distributional concerns make it harder and costlier for leaders to mobilize widespread and consistent support for claiming resource-rich lands. Using original geocoded data on territorial claims in South America from 1830 to 2001, I show that states are indeed less likely to claim lands that have oil or minerals, even when they can be claimed for historical or administrative reasons. I then illustrate the theoretical mechanism through a case study of Bolivia, comparing Bolivian attitudes toward reclaiming its two lost provinces, the Chaco and the Litoral. By showing how the presence of economic resources can become a liability in mobilizing unified support, this paper questions the widespread assumption that resources make territories more desirable to claim.

For many centuries, conquest was commonplace, and its attractiveness was central to the character of international politics. Why has it declined? Existing theories cannot explain why powerful countries no longer conquer states with easily extractable wealth. We develop an explanation based on the relationship between a potential conqueror's economic productivity and its ability to profit from conquest. Productivity has opposing effects on conquest's profitability: it raises the opportunity cost of each asset diverted to conquest, but also reduces the quantity of assets required for conquest. The net effect is determined by the composition of investment in innovation. We document that since at least 1950 investment has been predominantly aimed at civilian, not military innovations, so that rising productivity should reduce conquest's net profitability. Using cost analyses of comparable wars, we estimate bounds on the profitability of conquering the oil and gas reserves of the Persian Gulf, a very tempting target, for the United States and Iraq, two potential conquerors of widely differing productivity. Though both mechanisms operate, we find that the net effect of higher productivity is to reduce the profits from conquest. Moreover, this net effect is large enough to render conquest generally unprofitable for contemporary high-productivity states.

Past studies conclude that a territorial integrity norm caused territorial conquest to decline sharply after 1945, virtually subsiding after 1975. However, using new and more comprehensive data on territorial conquest attempts, this study presents a revised history of conquest after 1945. Unlike attempts to conquer entire states, attempts to conquer parts of states remained far more common than previously recognized. More than conquest declined in frequency, its relationship with war evolved. Challengers attempting conquest before 1945 often initiated a war, then sought to occupy large territories. Today, challengers more often seize small regions, then attempt to avoid war. Adopting this strategy, the fait accompli, challengers increasingly came to target territories with characteristics that reduce the risk of provoking war—such as a low population and the absence of a defending military garrison—but challengers nonetheless take a calculated gamble. In part because seizures of smaller territories with such characteristics have not declined, the operative constraint appears to be against war-prone aggression, not territorial revision. The evolution of conquest is a symptom of war's decline, not its cause. Most of the evidence that the territorial integrity norm suppressed conquest or war withers under investigation with new data. Attempts to get away with seizing small pieces of territory are likely to be a defining element of the twenty-first-century international security landscape.

This article examines a category of parastatates that has been largely neglected; the terrorist parastate. The main aim of the article is to fill this gap by scrutinizing the case of the Islamic State (IS), an organization that could be considered as the epitome of a terrorist parastate. Before the collapse of its territorial strategy in 2019, the group had targeted a significant number of states through terrorist attacks, while simultaneously controlling large swathes of territory and developing state-like institutions. During its buoyant period, IS called itself a state (Dawla), it viewed itself as a state (accomplishing a religious obligation), and perhaps more significantly, it was often perceived as a state by its enemies. The article will discuss the future prospects for the Islamic State after the collapse of its territorial/statehood strategy. After conceptualizing the nature of the terrorist parastate, the article will venture into comparative uncharted territory through an examination of the terrorist parastate vis-Á-vis its ordinary secessionist counterparts. One of the chief dissimilarities is the fact that IS, and terrorist parastates in general, tend to be less durable projects than secessionist parastates because they lack international sponsorship and they are more susceptible to foreign military interventions.

Although in principle states can bargain over the entire extent of their combined territory, we observe historically that states bargain within far more limited confines defined by well-bounded claims. We argue that this observation stems from the fact that states generally have limited territorial aims due either to limited benefits of obtaining additional territory and/or the costs of absorbing and controlling new territories and their inhabitants. Using a formal model, we show that introducing states with limited aims over territory has strategic implications for bargaining that have not been appreciated in canonical models that do not consider heterogeneity in state preferences. Whereas traditional models generally imply that small demands undermine the credibility of a challenger's threat, the existence of states with limited territorial aims makes limited demands credible, effective, and stable in the face of shocks to relative power. We then employ geospatial data on the geographic extent of territorial disputes in the period 1947–2000 to establish two results: the size of claims is weakly related to the relative power of disputants and unaffected by dramatic changes in power, and smaller claims are associated with a higher probability that the challenger will receive any concession.

This article draws on international relations theory to attempt a reframing of the Armenian–Azerbaijani conflict in Nagorny Karabakh as an enduring rivalry (ER): a particular kind of interstate conflict known for its longevity and stability. The article begins by identifying a number of conceptual deficits circulating around this conflict, notably the notion that it is a “frozen conflict,” before introducing the ER framework and its analytical dividends for this case. Different layers of the ER between Armenia and Azerbaijan are then explored at systemic, interstate, domestic, decision-maker, and temporal levels, with a view more toward identifying directions for future research than conclusive findings. Among the article's tentative conclusions are the primacy of endogenous over exogenous factors in explaining the durability of the rivalry between Armenia and Azerbaijan, the impacts of the passage of time on the human and physical geography of the territory under dispute, and the convergence of conflict dynamics across disparate levels.

Using a social representations lens, we examined subjective meanings of land entitlements in Central Mindanao among Muslims and Christians. In Study 1, we collected survey data from 231 students from the University of Southern Mindanao in Central Mindanao, asking them: ‘If you were to tell the story of land ownership in Cotabato, what three topics would you want to include in your story?’ Results of our hierarchical evocation analysis show that Christians are concerned with direct conflicts or actual intergroup confrontations while Muslims emphasise land issues. Study 2 implemented Focauldian Discursive Analysis to evaluate two separate focused group discussions by Muslim and Christian village leaders on the question: ‘Who really owns the land in Cotabato, specifically here in Midsayap?’ Findings indicate that Christians hold on to a legal story while Muslims use the ancestral domain narrative to cohere subjective claims to the contested territory. We discuss our results in the light of the role of legalese in an asymmetric territorial conflict and more specifically, the Framework Agreement signed last October 2012 by both the Philippine government and the Moro Islamic Liberation Front.

This article examines fractures in the social representations of a contested peace agreement in the longstanding territorial conflict of Mindanao. We compared representational structures and discourses about the peace talks among Muslims and Christians. Study One used an open-ended survey of 420 Christians and Muslims from two Mindanao cities identified with different Islamised tribes, and employed the hierarchical evocation method to provide representational structures of the peace agreement. Study Two contrasted discourses about the Memorandum of Agreement between two Muslim liberation fronts identified with separate Islamised tribes in Mindanao. Findings show unified Christians’ social representations about the peace agreement. However, Muslims’ social representations diverge along the faultlines of the Islamised ethnic groups. Findings are examined in the light of ethnopolitical divides that emerge among apparently united nonmigrant groups, as peace agreements address territorial solutions. Research results are likewise discussed in relation to other tribally contoured social landscapes that carry hidden, yet fractured ethnic narratives embedded in a larger war storyline.
