In 1989-1991, a whole world, perhaps many worlds, vanished: the worlds of socialism. In this graduate seminar we will investigate key cultural works, theoretical constructs and contexts spanning the socialist world(s), focused around the USSR, which was for many the (not uncontested) center of the socialist cosmos. Further, we will study the cultural and political interrelationships between the socialist world and anticolonial and left movements in the developing and the capitalist developed nations alike. Finally, we will investigate the aftermaths left behind as these world(s) crumbled or were transformed beyond recognition at the end of the twentieth century. Our work will be ramified by consideration of a number of critical and methodological tools for the study of these many histories and geographies. The purview of the course is dauntingly large—global in scale—and therefore “coverage” will of necessity be incomplete. In addition to the lead instructor, a number of guest instructors from Penn and from other institutions will join us to lead our investigations into specific geographies, moments and areas. Additionally, four weeks have been left without content, to be filled in via consensus decision by the members of the seminar.
