This volume which also appeared as a special issue of Medieval Encounters deals with transformations of the major Eurasian civilizations in the early second millennium CE, and with the question of contrasts, parallels and connections between the different trajectories that took shape during this period. An introductory section discusses the theoretical problems of comparative analysis, with particular reference to formative phases of cultural crystallization. The first main thematic section focuses on European developments. The emergence of Western Christendom as a distinctive civilization is analyzed in a broader Eurasian context. Other contributions examine the Europeanization of northern and eastern peripheries, as well as the different course of events in the Byzantine world. The last section covers socio-cultural changes in non-European regions - the Islamic world, India, China and Japan - and concludes with a discussion of the Eurasian empire created by the Mongols. With contributions by Thomas Lindkvist; Sverre Bagge; Paul Jakov Smith; Paul Stephenson; Mikael Adolphson; Dr. Michal Biran; Said A. Arjomand; Gabor Klaniczay; R. I. Moore; Sheldon Pollock.
