Since World War II, civil wars have replaced interstate wars as the most frequent and deadly form of armed conflict globally. How do we account for when and where civil wars are likely to occur, when and how they are likely to end, and whether or not they will recur? In this timely book, leading scholars accessibly guide students through cutting-edge research on the onset, duration, outcomes, and recurrence of civil wars, as well as the ongoing consequences of conflicts in war-torn countries such as Syria, Sudan, and Rwanda. In mapping out the current state of our knowledge about civil conflicts, the authors also identify what we do not know about civil wars.

With a consistent approach across chapters and through a wide variety of cases, the contributors collectively help readers understand some of the most pressing questions in conflict and security studies and illustrates how scholars answer them. This authoritative text offers both an accessible and current overview of the state of the field and an agenda for future research.
