Governance across borders or transnational governance looks at rule making, standard setting and institution building across borders. Empirically one can see the rise of a variety of patterns of regulatory governance. But transnational regulations are only one aspect of a whole field of transnational phenomena. Social life has always crossed, connected or transformed borders and boundaries.  Social processes have been transborder even before the spread of the nation-state system, as well as states also got shaped transnationally. Hirst and Thompson for example analyse different historical forms of transnational markets and long before the rise of the nation state.

Other transnational processes include transnational social movements, migration, communities, citizenship but also religion or various cultural practices (see for example Olgas entry on transnational ideas and local culture). In Europe, progress has been made specifically in regards to transnational phenomena within the European union, on debates about a European governance, public sphere or a collective identity (see for example also the new European Journal of Transnational Studies ) .

So far, there is no real discipline of transnational studies, but only a fragmented body of scholarship across sub-fields of sociology and other social science disciplines. To get into dialogue with and to learn from the insights of some of these studies, some general questions on transnationalism should be raised here, in a new series on transnational studies: What does it imply to analyze the global, national, local through transnational lenses for different approaches? Which phenomena are identified as transnational, how and why? How are the phenomena analyzed, how are flows or identities that cross certain spaces captured? How do transnational theories or theory building interact with traditional theories? And finally, what do all these different perspectives, including the governance research have in common, where are the biggest differences and what can we learn from each other? These are only some of the questions, which I think are important to discuss in order to be able to better understand transboundary social processes.
