Political transitions in a multiethnic setting are often marred with violence between groups. Why does ethnocommunal violence during a country’s democratic transition erupt in some places, and not others? Why does it subsequently decline? Existing explanations typically focus on the weakness of state capacity, the power struggle between political candidates around elections, or the structural factors such as economic inequality between groups. However, in many countries in transition, administrative units with similar characteristics have varying levels of violence. In this book, I build on Albert O. Hirschman’s framework of exit, voice, and loyalty, and I argue that excluded local elites mobilize violence to leverage their demands for greater inclusion in local politics during democratic transition. When these demands are accommodated, violence will decline. This chapter provides an overview of my theory, contributions to related literature, methodological approaches, key findings, and plan of the book.
