Why do rebel groups frequently clash instead of cooperating against their shared enemy, the state? Examining the dynamics of civil wars in Iraq, Ethiopia, Lebanon, Sri Lanka, and Syria, Costantino Pischedda argues that infighting is a calculated response by rebel groups to perceived opportunities and vulnerabilities.

This is the first book to examine and compare how rebels govern civilians during civil wars in Latin America, Africa, Asia, and Europe. Drawing from a variety of disciplinary traditions, including political science, sociology, and anthropology, the book provides in-depth case studies of specific conflicts as well as comparative studies of multiple conflicts. Among other themes, the book examines why and how some rebels establish both structures and practices of rule, the role of ideology, cultural, and material factors affecting rebel governance strategies, the impact of governance on the rebel/civilian relationship, civilian responses to rebel rule, the comparison between modes of state and non-state governance to rebel attempts to establish political order, the political economy of rebel governance, and the decline and demise of rebel governance attempts.

Why do only some incipient rebel groups become viable challengers to governments? Only those that control local rumor networks survive.

"In most societies, courts are where the rubber of government meets the road of the people. If a state cannot settle disputes and enforce its decisions, to all intents and purposes it is no longer in charge. This is why successful rebels put courts and justice at the top of their agendas. Rebel Law explores this key weapon in the arsenal of insurgent groups, from the IRA's 'Republican Tribunals' of the 1920s to Islamic State's 'Caliphate of Law,' via the ALN in Algeria of the 50s and 60s and the Afghan Taliban of recent years. Frank Ledwidge delineates the battle in such ungoverned spaces between counterinsurgents seeking to retain the initiative and the insurgent courts undermining them. Contrasting colonial judicial strategy with the chaos of stabilisation operations in Iraq and Afghanistan, he offers compelling lessons for today's conflicts"--Book jacket.

When insurgent organizations factionalize and fragment, it can profoundly shape a civil war: its intensity, outcome, and duration. In this extended treatment of this complex and important phenomenon, Michael Woldemariam examines why rebel organizations fragment through a unique historical analysis of the Horn of Africa's civil wars. Central to his view is that rebel factionalism is conditioned by battlefield developments. While fragmentation is caused by territorial gains and losses, counter-intuitively territorial stalemate tends to promote rebel cohesion and is a critical basis for cooperation in war. As a rare effort to examine these issues in the context of the Horn of Africa region, based upon extensive fieldwork, this book will interest both scholarly and non-scholarly audiences interested in insurgent groups and conflict dynamics.

Rebellion, insurgency, civil war-conflict within a society is customarily treated as a matter of domestic politics and analysts generally focus their attention on local causes. Yet fighting between governments and opposition groups is rarely confined to the domestic arena. "Internal" wars often spill across national boundaries, rebel organizations frequently find sanctuaries in neighboring countries, and insurgencies give rise to disputes between states. In Rebels without Borders, which will appeal to students of international and civil war and those developing policies to contain the regional diffusion of conflict, Idean Salehyan examines transnational rebel organizations in civil conflicts, utilizing cross-national datasets as well as in-depth case studies. He shows how external Contra bases in Honduras and Costa Rica facilitated the Nicaraguan civil war and how the Rwandan civil war spilled over into the Democratic Republic of the Congo, fostering a regional war. He also looks at other cross-border insurgencies, such as those of the Kurdish PKK and Taliban fighters in Pakistan. Salehyan reveals that external sanctuaries feature in the political history of more than half of the world's armed insurgencies since 1945, and are also important in fostering state-to-state conflicts. Rebels who are unable to challenge the state on its own turf look for mobilization opportunities abroad. Neighboring states that are too weak to prevent rebel access, states that wish to foster instability in their rivals, and large refugee diasporas provide important opportunities for insurgent groups to establish external bases. Such sanctuaries complicate intelligence gathering, counterinsurgency operations, and efforts at peacemaking. States that host rebels intrude into negotiations between governments and opposition movements and can block progress toward peace when they pursue their own agendas.

Why do rebel groups frequently clash instead of cooperating against their shared enemy, the state? This pattern occurs in conflicts around the world, yet it flies in the face of common notions of strategic logic. Weaving together insights from international relations theory and the study of ethnic politics, Costantino Pischedda presents an original theory to unravel the puzzle of inter-rebel conflict. Examining the dynamics of civil wars in Iraq, Ethiopia, Lebanon, Sri Lanka, and Syria, Pischedda argues that infighting is a calculated response by rebel groups to perceived opportunities and vulnerabilities. Conflicts break out between groups when one sees the potential to eliminate weaker rivals at a low cost or fears the deterioration of its power relative to a competitor and embarks on a desperate gamble. Counterintuitively, Pischedda finds that rebels sharing an ethnic identity are especially prone to violent conflict, as they see each other as both potential existential threats and enticing opportunities for expansion. Since coethnic rebels aspire to control the same community, their antagonism is stark and immediate. In addition, insurgents expect to be able to draw on the resources of defeated rivals from the same ethnic group more easily than they could on those of outsiders. Marshaling a range of data, Pischedda’s mixed-methods study features original interviews conducted with former insurgent leaders. The first book-length examination of inter-rebel fighting, Conflict Among Rebels sheds new light on a key question of civil war dynamics: why the enemy of my enemy is not always my friend.
