There has been renewed academic interest in the security impacts of forced migration since the start of the Syrian civil war in 2011 generated more than 5 million refugees, most of whom fled to neighboring countries and to Europe. Researchers are, for instance, increasingly working to identify how the type, severity, and perpetrator of political violence affect patterns of displacement, such as whether forced migrants cross borders or remain in their home country. Though much of the discussion in the security studies context continues to center on forced migration flows as a conduit for civil war, international terrorism, and refugees and internally displaced persons (IDPs) as perpetrators, scholars also have begun to focus attention on the ways in which refugees and the internally displaced can become the targets of political violence in the receiving state. Following the path of earlier qualitative research recognizing that displaced populations rarely become militarized, studies of a more quantitative orientation are now working to isolate the conditions under which forced migration leads to varying forms of political violence. Another important and growing area of focus is on how resettlement of the displaced affects the dynamics of violence in the origin country, including the potential for conflict recurrence. Efforts to study security impacts of forced migration more systematically have increased alongside the availability of new data and more diverse analytical tools and methods. Still, many important dimensions of the forced migration–conflict connection remain to be explored, and innovative research as well as new data collection efforts are necessary. Integrating insights from other fields, including economics, psychology, and sociology, and returning to the task of theory-building based on case-study research offer a promising path forward.
