The global refugee crisis represents a potential transformational moment in world history. Nations from Africa to Asia to Europe to North America with troubled pasts of ethnic conflict and of putting political and economic self-interest above humanitarian needs have an opportunity to write new chapters in their national stories. Religion is playing and will play a critical role.

Religious fashion matters. It matters to individuals who view wearing head scarves, kippas and turbans as a positive expression of faith, and it matters to societies increasingly setting restrictions on religious attire in response to concerns ranging from security to the belief that increasing diversity represents a threat to the essential character of their nations. So how, in the face of intense political and social pressures, can nations balance issues of religious freedom, tolerance and national identity? A developing body of research sheds some light on the debate.
