Upon his death, Charlemagne's Empire split into three different kingdoms, which continued to divide, eventually becoming France and Germany. The German states remain confederated under the Holy Roman Empire. England has been united under the Normans. The Roman Empire is a shadow of its former self, reeling in the aftermath of the sack of Constantinople during the Fourth Crusade. Poland has begun to emerge as a Slavic power in eastern Europe, and the Magyar people have settled down in Hungary. However, none can challenge the strength of the Mongol Empire as it spreads across the Continent.
