The combination of state, territory and identity is at the core of the studies on transnationalism and globalisation. Studies on globalization focus on new dynamics and new configurations between network, space and territory and their interdependence. We are witnessing mobile societies. Spatial extension of citizenship, migrations, and the emergence of global markets have all created a “spatial turn” in social sciences according to Neil Brenner. So-called transnational political actions, those that reach beyond borders, are creating a space of identification beyond national societies; a space that, in its quest for power, seeks to combine the local and the global. The mobile body thus outlines a new, denationalized and deterritorialized geography that is transforming states: national borders are still clearly drawn, but they are traversed by a mesh of networks that crisscross in space as if to define a new form of territoriality, characterized nevertheless by the extension of state sovereignty. While bounded national territories remain the place where power is spatially concentrated, new “geographies of power” are represented by networks and lead us to consider two manifestations of power acting at the same time: a territorial and a non territorial power. Transnational communities born out of such networks are defined also as a movement that is seeking a new, non-territorialized center, denationalized with respect to the countries of origin. The rhetoric of mobilization recentralizes in a non territorial way the internal heterogeneity of the network in order to create a unified “us” that is non-national, not territorial, and situates itself in the process of globalisation. The relationship between state-territory and identity raises normative questions on nation states and their singular power and action. It raises institutional and cultural questions with regard to mobilization of actors and institutions such as NGOs Human Rights organizations etc. It also raises juridical questions mainly on how transnationalism gives new strength to the national question and becomes a stake of legitimacy in the international system. This interdisciplinary course will try to answer these questions from different examples of experiences based on networks, institutions, cultures, sites and causes for mobilization.
