How does interstate rivals’ intervention in a third-party civil war impact conflict duration and outcome in that country? More specifically, (1) how do interstate rivals engage in third party civil conflicts and (2) how do conflict parties attract, utilize, and sustain the external support they receive from their supporters? I answer these questions by comparing Saudi Arabia and Iran’s intervention in two distinct conflicts in Yemen. This dissertation applies a qualitative case study method and selects two within-case methods: structured-focused comparison and process tracing. In the structured-focused comparison, I compare the support Saudi Arabia and Iran has provided to the Government of Yemen (GoY) and the Houthis respectively, differentiating between military and non-military types of support. I compare these during the Saada wars (2004-2010) and in the current internationalized civil war (2014-2018). To ensure the validity of my causal inferences I triangulate data from three sources: the development of a novel mediation and ceasefire dataset1 (1), semi-structured in-depth elite-interviews2 (2), and document reviews (3). This dissertation develops a mechanism-focused analytical framework that integrates both rivalry and civil war dynamics to explain civil war duration and outcome. I build on five distinct literatures (strategic rivalry, civil war studies, third-party intervention in civil wars, mediation, and rebel governance) and complement them with the literature on Middle East Area Studies. In the analytical framework first, I look at the inter-state dimension and propose that rivals’ initial decision to intervene and their subsequent decisions to remain engaged in third-party civil wars are two distinct processes. Rivals seek to inflict costs on their counterparts, but at the same time they seek to avoid direct confrontation. Their cognitive rigidities lock them in their own conflicts and give rise to the mechanism of conflict integration in third-party conflicts. Besides interveners, I also take into account domestic dynamics and examine civil war conflict parties’ capacity to impact rivals by keeping them engaged in their conflict through the mechanism of rivalry instrumentalization. The external and internal perspectives are reinforcing each other and create networked interdependencies. With this two-dimensional logic, I move beyond the conventional framework of proxy wars.

What factors influence third parties to intervene in civil wars? Our focus on major powers, which are disproportionately more likely than other states to intervene in civil conflicts, directs us to the factors that uniquely shape their interests. While our study does not rule out humanitarian interventions by collective security international institutions and individual states, we do not find that humanitarian concerns motivate major powers. We argue and demonstrate that their decisions to intervene are principally motivated by their drive to establish, consolidate, or expand influence in different geopolitical regions. Past research with the strategic approach stressed the importance of an intervener’s prior ties with a civil war state for this decision. Though important, we show the effect of these ties is subordinate to other factors. In our argument, their role is primarily relevant for determining whether an intervener will be on the side of the government or opposition. The key issue of whether major powers are likely to intervene in the first place, however, is contingent on how much the entire region is strategically relevant to warrant intervention. The empirical analysis of civil war interventions over nearly fifty years lends strong support to our theoretical expectations.

Civil war is an armed conflict between the state and another organized domestic party over a contested political incompatibility, which results in a number of casualties exceeding a certain threshold for both parties. Attempts to operationalize these criteria have produced many data sets, which conceptualize civil war as distinct from one-sided violence, organized crime, and communal fighting. Civil wars are devastating for states experiencing them, their neighbors, and the entire global community. Combatant and civilian deaths, rape, massive refugee flight, negative impacts on economy and infrastructure, spread of infectious diseases, global spread of illegal narcotics, and the promotion of terrorism are all consequences of civil wars. Theories explaining why civil wars occur focus on objectives of the rebels, ability of rebels to successfully challenge the government, influence of external actors on interactions between the government and the opposition, external financing of potential rebel groups, and impact of a state’s neighbors on the likelihood of civil conflict or how neighboring conflicts and refugee communities serve as breeding grounds for cross-border rebel movements. Conflicts persist until neither side believes that it can achieve unilateral victory and continued fighting is costly. Governments are more likely to win early when they have large armies, but time to government victory increases when they are faced with secessionist rebels and when external parties are involved. Meanwhile, external mediation diminishes informational and credible commitment problems during bargaining and reduces conflict duration. Promising directions for future research on civil war include geographic disaggregation, survey research, and computational/agent-based modeling.

Abstract Previous research has shown that the outcome of a civil war is related to conflict duration: military victory by either the government or the rebels occurs early if it occurs at all, and the longer a civil war lasts, the more likely it is to end in a negotiated settlement. The models of civil war duration and outcome that have produced these findings are built on characteristics of the civil war and less on attributes of the state itself, other than where the state lies on the Polity autocracy-democracy scale. We propose that how civil wars end varies not only between democracies and authoritarian regimes but among the different authoritarian regime types identified by Geddes, Wright, and Franz. The distinguishing attributes of these regime types—democracy, one-party, personalist, military, monarchical—should lead to different likelihood in defeating a rebel movement, being defeated by a rebel movement, and negotiating a peace agreement with a rebel movement. Results from a series of competing-risk models using the Uppsala–Peace Research Institute Oslo Armed Conflict Dataset demonstrate support for our claim that how civil wars end is partly a function of the characteristics of the regime.

Many studies highlight the role that international intervention can play in prolonging civil wars. Yet, direct military intervention is just one way that external actors become involved in civil conflicts. In this article, a model is developed and analyzed that shows that when the government is unsure about how external support to the rebels will help rebel war-making capacity, it is the government that will continue fighting rather than settle the dispute. Different types of external support to rebels influence their fighting capacity differently, and some types of support create uncertainty about how new resources will translate into war-making ability. Specifically, more fungible sources of support (such as direct financial support) generate the most uncertainty for states as they attempt to estimate the effect of support to rebels on the conflict. Increased uncertainty inhibits bargained settlement, and disputes characterized by fungible external support are less likely to end than those where rebels receive different kinds of support. Empirical analyses demonstrate strong support for this argument; rebels that receive highly fungible external support (money and guns) are less likely to see conflict termination than rebels that do not.

Abstract Governments grant amnesties to rebel groups during civil wars and this is a puzzle. Why would the government offer an amnesty, which can be interpreted as a signal of weakness? In certain circumstances, offering amnesty is a rational policy choice. Governments should give amnesties when they are winning: the risk of misinterpreted signals is lessened, costs are low, rebel groups are weakened, and so amnesty can be used instrumentally to encourage defection or division among foot soldiers or as an incentive to leaders. Therefore, the government capitalizes on its military advantage and offers amnesty in a “stick then carrot” tactic. Using a database of amnesties during conflicts from 1990 to 2011, the article shows that governments are more likely to give amnesties following high rebel deaths. The use of amnesty during conflict is nuanced and context is important when understanding strategic choices.

AbstractA broad literature on how oil wealth affects civil war onset argues that oil production engenders violent contests to capture a valuable prize from vulnerable governments. By contrast, research linking oil wealth to durable authoritarian regimes argues that oil-rich governments deter societal challenges by strategically allocating enormous revenues to enhance military capacity and to provide patronage. This article presents a unified formal model that evaluates how these competing mechanisms affect overall incentives for center-seeking civil wars. The model yields two key implications. First, large oil-generated revenues strengthen the government and exert an overall effect that decreases center-seeking civil war propensity. Second, oil revenues are less effective at preventing center-seeking civil war relative to other revenue sources, which distinguishes overall and relative effects. Revised statistical results test overall rather than relative effects by omitting the conventional but posttreatment covariate of income per capita, and demonstrate a consistent negative association between oil wealth and center-seeking civil war onset.

The vast majority of work on the ethics of war focuses on traditional wars between states. This chapter aims to show that this is an oversight worth rectifying. The strategy is largely comparative, assessing whether certain claims often defended in discussions of interstate wars stand up in the context of civil conflicts and whether there are principled moral differences between the two types of case. Firstly, the chapter argues that thinking about intrastate wars may help us make progress on important theoretical debates in recent just war theory. Secondly, it considers whether certain kinds of civil wars are subject to a more demanding standard of just cause, compared to interstate wars of national defence. Finally, it assesses the extent to which having popular support is an independent requirement of permissible war and whether this renders insurgencies harder to justify than wars fought by functioning states.

Extant research shows that the presence of natural resources can prolong civil wars. But research also indicates that as rebel groups become stronger, conflicts tend to shorten. These studies suggest an unclear association among the three variables—resources, rebel strength, and conflict duration. If resources increase the fighting ability of rebels, then why do they not shorten conflicts? To understand this relationship, we examine incidents of maritime piracy, which unlike other resources are more clearly exploited by rebel groups rather than states and offer new insight on how this might affect the persistence of civil war. The findings suggest that the use of piracy by weaker rebel groups shortens conflict but prolongs it when exploited by stronger rebel groups. We think our conditional analyses allow us to discern insurgencies driven at least in part by greedy rebels and therefore better illuminate the causal process by which resource wealth prolongs civil war.

Abstract This article develops a theory of competitive intervention in civil war to explain variation in the global prevalence of intrastate conflict. I describe the distortionary effects competitive interventions have on domestic bargaining processes and explain the unique strategic dilemmas they entail for third-party interveners. The theory uncovers the conditional nature of intervention under the shadow of inadvertent escalation and moves beyond popular anecdotes about “proxy wars” by deriving theoretically grounded propositions about the strategic logics motivating intervener behaviors. I then link temporal variation in patterns of competitive intervention to recent decreases in the prevalence and average duration of internal conflicts. The theory is tested with a quantitative analysis of all civil wars fought between 1975 and 2009 and a qualitative case study of the Angolan civil war (1975–1991). My results underscore the importance of a generalizable account of competitive intervention that not only explains past conflicts, but also informs contemporary policy.

Abstract We build a model for predicting civil wars where the government bargains with a rebel group using concessions and repression. The equilibrium is either a state of perpetual peace where there are concessions but no repression or a state of repressive equilibrium that can lead to civil wars. At the lowest levels of political competition, a move towards open electoral participation decreases the ability of the state to use repression to limit challengers, increasing the likelihood of war. At higher levels, an increase in competition decreases the probability of war by increasing concessions to the rebel group. Increasing concessions makes war less likely because it decreases the spoils of war and provides one explanation for the non-monotonicity found between probability of civil war and democracy. We test the prediction of this non-linearity using the technique in [Hansen (2000). “Sample Splitting and Threshold Estimation.” Econometrica 68:575–603] and find evidence consistent with the model.
