What makes globalization even possible in the first place? One answer would be that it requires the regularization of some kind of media and communication infrastructure. When you have that, you might get globalized economic trade within some political or imperial framework, but it is likely you'll get transnational cultural flows as well. Globalizing trade can lead to a cosmopolitan culture, but also to all sorts of nationalistic or racist or patriarchal reactions to those as breaches of imaginary communities.
