This Element seeks to make sense of Southeast Asia's numerous armed conflicts. It makes four contributions. First, this study provides a typology, distinguishing between revolutionary, secessionist, and communal conflicts. The first two are types of insurgencies, while the latter are ethnic conflicts. Second, this study emphasizes the importance of ethnicity in shaping conflict dynamics. This is true even for revolutionary conflicts, which at first glance may appear unrelated to ethnicity. A third contribution relates to broad conflict trends. Revolutionary and secessionist conflicts feature broad historical arcs, with clear peaks and declines, while communal conflicts occur more sporadically. The fourth contribution ties these points together by focusing on conflict management. Just as ethnicity shapes conflicts, ethnic leaders and traditions can also promote peace. Cultural mechanisms are especially important for managing communal conflicts, the lone type not declining in Southeast Asia.

Internal Migration: Challenges in Governance and Integration focuses on the challenges associated with internal migration across the developing world. While international migration captures significant attention, less attention has been paid to those migrating within recognized national borders. The sources of internal migration are not fundamentally different from international migration, as migrants may be pushed by violence, disasters, state policies, or various opportunities. Although they do not cross international borders, they may still cross significant internal borders, with cultural differences and perceived state favoritism generating a potential for "sons of the soil" conflicts. As citizens, internal migrants are in theory to be provided legal protection by host states, however this is not always the case, and sometimes their own states represent the cause of their displacement. The chapters in this book explain how international organizations, host states, and host communities may navigate the many challenges associated with internal migration.
