Political dynamics and outcomes around the globe have been transformed by globalization, new patterns of human mobility, and the development of innovative transnational social networks. These new political processes are rooted in communities and networks that are not restricted by geographic location. Although politics has been delinked from territory in this way with regard to processes and actors, this does not mean that transnational politics focuses exclusively on universal issues or global approaches to social justice. Rather much of the new transnational politics is intensely focused on specific locations, identities, and issues (for example, “globalized” neighborhood associations, ethnicities, patrimonialism). Transnational politics also includes new conceptions and practices of citizenship and accountability (for example, legislative seats reserved for expatriate labor migrants) as the body politic becomes increasing mobile, political affinities delinked from geographic proximity, and critical constituencies reside outside of the territory of the state. This article outlines a new approach to investigating the actors and processes at the heart of contemporary transnational politics, with a particular focus on the ways in which diasporas are strategically constructed and mobilized to advance political goals through the use of salient symbols, identity frames, and social networks.
