The MPI MMG is one of the foremost centers for the multi-disciplinary study of diversity, in its multiple forms, in today’s globalizing world. As societies across the globe become ever more diverse, pressing new challenges emerge to the fore, motivating the study of questions such as the relationship between mobility and inequality; the interaction of globalization, religious diversity, and the secular state; the legal boundaries of cultural accommodation; global cities and super-diversity within them; new forms of membership and belonging; and the trans-bordering networking of ethnic and religious minorities.
