Continuous movements of peoples, cultures and individuals characterize the contemporary world. Population movement not only affects those who move, but also those who are left behind, altering many of our relationship to homeland, family, the state and society. Focusing on various forms of migration and displacements within the Middle East, this theme addresses the nature of diasporic social networks, identities and cultures, and the effects of different axes of power such as social status, gender, religion and sexuality on the experiences of migration and displacement. Attention is given to a variety of notions, for example, of home, memory, belonging, identity, exile, nomadism, and hybridity. Through the use of qualitative and quantitative research methods and spatial analysis techniques, we examine the ways various diaspora groups interact within the group, with their homelands and their host societies. In this regard, we will analyze the influences non-static diasporas have on their homelands and host societies socially, politically, and culturally, but also, for example, political, social and religious diversities within groups and between groups. Finally, we investigate whether if diasporas contribute to the rise of a global society, taking into consideration processes that strengthen as well as weaken the rise of a universal solidarity and cosmopolitan identities.
