Inter-Rebel Alliances in the Shadow of Foreign Sponsors

From the Patriotic Front struggle against the minority rule in Rhodesia to the seven-party mujaheddin alliance in Afghanistan, inter-rebel alliances make the armed opposition more resilient and successful in the face of government repression. Why then do some rebel groups cooperate with each other while others do not? Drawing on the principal-agent theory, I argue that the presence of foreign sponsors is likely to encourage alliance formation in civil wars especially when two rebel outfits share a state sponsor. Shared sponsors may demand cooperation between their agents and credibly threaten to punish them for non-compliance. They may also insist on the establishment of umbrella institutions to improve their monitoring and sanctioning capacity, and to increase the legitimacy of their agents. I test this argument using the UCDP Actor dataset with new data on alliances between rebel groups. I find strong evidence that shared sponsors increase the probability of inter-rebel alliance.     

Civil War Diffusion and the Emergence of Militant Groups, 1960–2001

In this research note, I argue that scholars of the international diffusion of civil conflict would benefit from directly measuring rebel mobilization prior to the onset of civil war. To better understand the way in which international processes facilitate dissidents overcoming the collective action problem inherent in rebellion, I focus on militant organizations and model the timing of their emergence. I use several data sets on militant groups and violent nonstate actors and rely on Buhaug and Gleditsch’s (2008) causal framework to examine how international conditions predict militant group emergence. While Buhaug and Gleditsch conclude that civil war diffusion is primarily a function of internal conflict in neighboring states, once militant group emergence is substituted in the dependent variable, I observe that global conditions affect rebel collective action. A final selection model links militant groups with civil conflict onset and demonstrates the variable performance of diffusion effects. The results indicate that many rebels mobilize in response to more global events and then escalate their behavior in response to local conditions.     

Civilian self-defense militias in civil war

To mitigate the costs associated with suppressing rebellion, states may rely on civilian self-defense militias to protect their territory from rebel groups. However, this decision is also costly, given that these self-defense groups may undermine control of its territory. This raises the question: why do governments cultivate self-defense militias when doing so risks that these militias will undermine their territorial control? Using a game theoretic model, we argue that states take this risk in order to prevent rebels from co-opting local populations, which in turn may shift power away from the government and toward the rebels. Governments strategically use civilian militias to raise the price rebels must pay for civilian cooperation, prevent rebels from harnessing a territory’s resources, and/or to deter rebels from challenging government control in key areas. Empirically, the model suggests states are likely to support the formation of self-defense militias in territory that may moderately improve the power of rebel groups, but not in areas that are either less valuable or areas that are critical to the government’s survival. These hypotheses are tested using data from the Colombian civil war from 1996 to 2008.     

Battle Losses and Rebel Violence: Raising the Costs for Fighting

In many armed conflicts, rebel groups deliberately target civilians. This article examines whether such violence is related to the performance of the rebels on the battlefield. It is proposed that rebel groups who are losing battles target civilians in order to impose extra costs on the government. When rebels attack civilians, the government may incur both political and military costs. Violence against civilians is thus used as an alternative conflict strategy aimed at pressuring the government into concessions. The argument is evaluated by using monthly data for rebel groups involved in armed conflict from January 2002 to December 2004.     

Rebel Behavior in the Context of Interstate Competition: Exploring Day-to-Day Patterns of Political Violence in Africa

This study develops a day-to-day theory of political violence that predicts that rebels respond strategically to the onset of interstate conflict that is directly related to a civil war. Government-initiated interstate conflict is theorized to incentivize rebels to signal their resolve, willingness to bear costs, and vulnerability of government forces. In addition, this form of interstate conflict is predicted to decrease violence against civilian populations, as it makes it more likely that rebels will need to rely on civilians for resources in the future. This is contrary to interstate conflict initiated by an external state, as this signal of third-party support makes civilian support more dispensable from the perspective of a rebel movement. Using a country-day data set constructed from event data, evidence is presented that is consistent with this theoretical logic. Interstate conflict, therefore, is shown to play a significant role in explaining the variation of violent events that occur on a day-to-day basis during a civil conflict.     

“The War Will Come to Your Street”: Explaining Geographic Variation in Terrorism by Rebel Groups

Geographic variation in rebels’ use of terrorism is not well understood. This article explains the use of terrorism in civil conflict through examining geographic variation in terrorist attacks across first–level administrative regions. Two explanations are tested using data on 47 groups in 21 countries: that terrorism is intended to punish supporters of counterinsurgency efforts or to destabilize regions of the country that are both outside of rebels’ military reach and have substantial grievances against the regime. Results show that terrorism is most prevalent in national capitals and regions that are more deprived. The findings suggest that rebel groups face multiple incentives for violence beyond zones of direct military confrontation with the government, using both highly visible attacks against the center of power and attacks intended to geographically expand the rebellion. The findings imply maximizing public service provision and minimizing economic inequality may reduce the breadth of rebels’ potential expansion.     

Intraethnic Dominance and Control: Violence Against Co-Ethnics in the Early Sri Lankan Civil War

In some ethno-separatist wars, rebel groups direct a large share of violence against members of their own ethnic community. But why do rebels target the co-ethnics they claim to represent in the war against the government? Our aim in this paper is to provide the components for a conceptual framework that we assess using unique disaggregated casualty data on violence committed by the Liberation Tigers of Tamil Eelam against co-ethnic Tamils in territories claimed for the Tamil Eelam state in the early phase of the Sri Lankan conflict, 1985–88. We propose that there are two distinct processes of intraethnic violence: violence against co-ethnic civilians and violence against co-ethnic rivals. While the former aims at controlling the population to win the war against the government, the latter aims at establishing leadership dominance over the ethnic minority. We examine the role of ethnic homogeneity in shaping the use of violence directed against the two types of co-ethnic targets in the buildup phase of ethno-separatist war. We conclude that ethnic demographic structures matter for how the rebels treat co-ethnics in the early phase of war before they have established territorial control.     

Selling to Both Sides: The Effects of Major Conventional Weapons Transfers on Civil War Severity and Duration

Civil wars are primarily fought with small and light arms, but the availability of major conventional weapons to states and rebels can alter the nature of the war being fought. This study explores the impact of major conventional weapons transfers on civil war severity and duration. By using a recipient based approach to arms transfers, I find rebel acquisition of major conventional weapons from international sources leads to conflict escalation and deadlier conflicts. State importation of major conventional weapons is associated with longer conflicts. These findings provide researchers a means to account for rebel capabilities in civil war research and policy makers insight to limit the destructiveness of civil wars.     

The Loyalty Trap: Regime Ethnic Exclusion,Commitment Problems,and Civil War Duration in Syria and Beyond

This article examines the impact of the ethnic exclusiveness of regimes on commitment problems and hence on civil conflict duration. It argues that members of privileged in-groups in highly exclusive regimes can be trapped into compliance with the regime. Ethnic exclusion helps to construct privileged-group members as regime loyalists. They therefore fear rebel reprisals even if they surrender or defect and consequently persist in fighting. The article finds in particular that, in ethnically exclusive regimes, privileged-group members mistrust even rebels who mobilize on a nonethnic agenda and regard rebel reassurances, including nonethnic aims, as suspect. Exclusion therefore induces privileged-group cohesion, an effect more resistant to rebel reassurances than previously recognized. A case study of the Syrian civil war shows this dynamic at a micro level, and a cross-national statistical analysis gives partial evidence that it lengthens civil conflicts on a larg`e scale.     

How Can Weak Insurgent Groups Grow? Insights From Nepal

How can insurgent groups that are militarily far weaker than the state survive and grow? Influential accounts drawing on Kalyvas' “control-collaboration” model argue that limited state reach can make this possible by allowing rebel groups to carve out pockets of control where they can elicit collaboration. I suggest that this account is inadequate. Even states with limited reach are likely to transfer sufficient forces to rebel-affected areas to establish at least partial control. Weak rebels therefore often face the challenge of building capacity without local control to begin with. I identify two broad factors that can make this feasible: first, strong pre-existing rebel networks, which facilitate collaboration through solidarity, norms of reciprocity, and social incentives; and second, counterinsurgency policies and practices that fail to exploit the opportunities that control offers for incentivizing collaboration and shaping political preferences. These arguments are grounded in a fieldwork-based case study of insurgency processes in a hamlet of Rolpa, Nepal.     

The Role of Political Exclusion and State Capacity in Civil Conflict in South Asia

Extant literature on intrastate conflict independently explores terrorism and civil war. However, both terrorism and civil war are probably parts of a continuum of intrastate conflict with the former at one end and the latter at the other end in terms of intensity. I argue that two factors play important roles in rebels’ decision-making calculus, namely, the size of their support base and state strength. Terrorism, as a strategy of the weak, is optimal when the rebel groups have little support among their audience and the state is strong. On the other hand, guerrilla warfare is an ideal strategy when such groups have a greater support base and the state is weak. The theoretical argument is tested on a dataset of Myanmar and six countries of South Asia and for 1970–2007.     

Ripening Within? Strategies Used by Rebel Negotiators to End Ethnic War

This article explores what strategies rebels use to prepare their ethnic community for negotiated peace. Proposed strategies are distilled from relevant theory and systematically investigated in case analyses of peace negotiations in Sri Lanka, Indonesian Aceh, and Senegal. The empirical findings indicate that although a coercive military capacity underpinned claims to ethnic representation, coercion did not dominate during the prenegotiation phase. During negotiations, noncoercive persuasion, as well as collective and selective incentives, clearly dominated. Moreover, the most important measures were internal to the negotiating rebel group. The successful rebel negotiator appeared to “mobilize in reverse” by initially targeting the core of military leaders followed by competitor groups and constituents. The article systematically examines across cases what measures rebel negotiators have used to “ripen” their own community, how these measures have been sequenced, and against whom they have been directed. The findings have important implications for the concepts of ripeness and prenegotiation and their requirements. The study underscores in particular the relevance of rebels' nonviolent commitment signals, something that has been largely overlooked in the research on nonstate armed actors. The policy implications suggest the possible benefits of third‐party assistance to efforts to promote communication, public outreach, and procedural transparency on the nonstate side in connection with peace talks.     

The Arsenal of Insurrection: Explaining Rising Support for Rebels

Recent scholarship has established several key dynamics in civil wars: since the nineteenth century, rebel victories have increased in likelihood; external support is one of the most significant predictors of rebel victory; and rebel groups have become increasingly likely to receive foreign backing. What is missing is an explanation of why patterns of third-party aid to rebels changed over time. Data on foreign assistance to rebels over the last two centuries reveals the odds of groups receiving aid increased from about one in five to about four in five. The nature of the patron also altered significantly, from great powers, to lesser states, and then nonstate actors. We explain these patterns using three variables: (1) great-power competition; (2) norms of national self-determination; and (3) globalization. This paper explores this theory with a case study of aid to rebel groups in Algeria since the 1830s.     

Attacks on Civilians in Civil War: Targeting the Achilles Heel of Democratic Governments

Previous research has indicated that democracy decreases the risk of armed conflict, while increasing the likelihood of terrorist attacks, but we know little about the effect of democracy on violence against civilians in ongoing civil conflicts. This study seeks to fill this empirical gap in the research on democracy and political violence, by examining all rebel groups involved in an armed conflict 1989–2004. Using different measures of democracy, the results demonstrate that rebels target more civilians when facing a democratic (or semi-democratic) government. Democracies are perceived as particularly vulnerable to attacks on the population, since civilians can hold the government accountable for failures to provide security, and this provides incentives for rebels to target civilians. At the same time, the openness of democratic societies provides opportunities for carrying out violent attacks. Thus, the strength of democracy—its accountability and openness—can become an Achilles heel during an internal armed conflict.     

Balance of Loyalties: Explaining Rebel Factional Struggles in the Nicaraguan Revolution

Abstract

What explains the causes and outcomes of rebel factional struggles? Existing explanations focus on exogenous and material factors that disrupt rebel organizations’ internal processes. Yet rebel groups succumb to infighting and organizational splinters even in the absence of external shocks. In this article I present an endogenous and social theory of rebel factional struggles, in which leadership disputes result from a shifting balance of loyalties within a rebel organization. In my model, rival rebel leaders cultivate the loyalty of two types of networks, recruitment networks and operational networks, which serve as power bases to initiate leadership struggles, launch coups, or split organizations. I build my theory through a case study of Nicaragua’s Frente Sandinista de Liberación Nacional (FSLN), which splintered into three factions in 1975–76. Drawing on an original network dataset of FSLN commanders, I trace how the organization’s network structure changed over time, spurring disputes over rank-and-file fighters’ loyalties that tore the FSLN apart.     

Bargaining Between Rebel Groups and the Outside Option of Violence

Although military cooperation among rebel groups in multi-party civil wars could help rebels defeat or extract concessions from an incumbent government, violent conflict among rebel groups is empirically prevalent. Why do rebel groups in multi-party civil wars choose to fight one another? This article models the strategic dilemma facing rebel groups in multi-party civil wars as an alternating-offer bargaining game of incomplete information with an outside option. The game-theoretic model explores the relationship between the status quo distribution of power among rebel groups, the costs of fighting, and the likelihood that one rebel group will opt to unilaterally end bargaining over a set of goods, such as access to supply routes, natural resources, and control over civilian populations. We show that the likelihood of violent conflict between rebel groups is lowest when the status quo distribution of benefits reflects the existing distribution of power.     

Strategic rebels: a spatial econometric approach to rebel fighting durations in civil wars

ABSTRACT

Recent research on multi-actor civil wars highlights that rebel organizations condition their conflict behavior on that of other rebel organizations, with competition and free-riding constituting the core theoretical mechanisms. We provide a new actor-centric approach to explicitly model strategic interdependence in multi-actor civil wars. We argue that rebel organizations have incentives to remain mobilized until the end of a conflict to maintain their power to negotiate, power to spoil, power to enforce, and power to protect. This induces strategic complements that dominate duration dynamics in multi-actor conflicts. Based on a network game-theoretic model, we derive a spatial econometric framework that allows for a direct test of strategic interdependence. We find that the estimated duration interdependence is positive but partially offset in secessionist conflicts where the public goods nature of the incompatibility also induces strategic substitution effects.     

Battlefield Outcomes and Rebel Cohesion: Lessons From the Eritrean Independence War

This article uses data from the Eritrean war for independence to refine existing theories of rebel fragmentation. The author argues organizational performance affects the emergence of factional infighting within rebel organizations in unique and novel ways. While battlefield losses increase the likelihood of internal fragmentation, so do battlefield gains. The implication is battlefield stalemates possess unique properties that promote organizational cohesion in war, a relationship this study refers to as “cohesive stalemates.” The article extends an emerging literature on the internal politics of insurgent groups that has linked the coherence of rebel organizations to rebel losses.     

Individual-Level Data on the Victims of Nepal’s Civil War, 1996–2006: A New Data Set

This article introduces individual-level microdata on victims of violence in Nepal’s civil war (1996–2006). The data being presented in this study are unique in that they are a census—not a sample—of the known population of victims for which information could be collected. The unit of analysis is the individual victim, and the data provide information on: whether the victim was killed, injured, or disappeared; the districts and villages where they were targeted; their permanent home addresses; the circumstances of the attack (combat, extrajudicial, etc.); socioeconomic information; whether they had any affiliation to rebel groups or other political parties; identification of the perpetrator; and whether the victim was considered to be a government or Maoist informant. After describing the data, an application of the data is performed and some preliminary findings are discussed on the differences in targeting behavior between the government and the Maoist rebels.     

Challenging the State: Effect of Minority Discrimination,Economic Globalization,and Political Openness on Domestic Terrorism

Discrimination against minority groups is a robust predictor of domestic terrorism. However, economic and political openness might further facilitate mobilization of such aggrieved sections of a larger population. This study relates economic and political openness to minority discrimination in explaining vulnerability to domestic terrorism. Terrorism is a rational choice when a minority’s deprivation of public good provisions increases, while global economic integration and limited political openness facilitate rebel mobilization. Using data on 172 countries, I find strong support that countries discriminating against minority groups are more likely to experience domestic terrorist attacks when their economic and political systems open up.
