Why did European history come so late to the global turn? Europe’s past had of course always been constructed relative to its Islamic or Mongol peripheries, and later its colonial offshore. But only recently has it been understood that European and extra-European history are in a dynamic relationship of reciprocal influence. Intellectual and economic history recognized this before social history, which in its post-1960 flowering took it for granted that European social forms were both more advanced and categorically different from others. During the 1970s and 1980s, however, a generation after political decolonization, new work began to explore the impact of peripheries on the European core and to measure Europe from the outside. After 2000, a globalized European social history became visible. Its evasion of the constraints of the national paradigm has opened up striking new pan- and trans-European historical projects and methods. These are provoking new questions of how we might reconfigure European history in ways which understand eastern and central Europe in their own terms, rather than simply as the retarded extensions of “advanced” western European phenomena.
