Accelerated migration has been an important impetus for the study of borders and borderlands, with postcolonial, feminist, and ethnic studies scholars building a rich body of work on the implications of its processes for notions of identity, culture, and citizenship. Work on diaspora, transnationalism, and cosmopolitanism has shed light on the ways in which mobility and nomadism are always in tension with confinement and encagement, addressing key questions of who is allowed to move across national borders, how, and for what purposes. The militarization of borders, embedded in global regimes of surveillance and securitization, has led to practices of violent enforcement of restrictions against crossing borders as well as incarceration and deportation. Militarization is both touted as a means of controlling border violence and criticized as a source of violence, whether directly or indirectly. We will bring together conversations in immigration studies, postcolonial studies, indigenous studies, and critical prison studies that interrogate the ways in which the right to freedom of movement is constrained by regimes of global capitalism, militarism, incarceration, organized crime networks, and (settler) colonialism and that offer new ways of rethinking mobility.
