when did the first slavs get to eastern europe
Slavs Around the 6th century, Slavs appeared on Byzantine borders in great numbers.[16][pageÂ needed] The Byzantine records note that grass would not regrow in places where the Slavs had marched through, so great were their numbers. After a military movement even the Peloponnese and Asia Minor were reported to have Slavic settlements.[17] This southern movement has traditionally been seen as an invasive expansion.[18] By the end of the 6th century, Slavs had settled the Eastern Alps regions.
Mongol invasion of Europe The operations were planned by General Subutai (1175–1248) and commanded by Batu Khan (c. 1207–1255) and Kadan (d. c. 1261). Both men were grandsons of Genghis Khan; their conquests integrated much European territory to the empire of the Golden Horde. Warring European princes realized they had to cooperate in the face of a Mongol invasion, so local wars and conflicts were suspended in parts of central Europe, only to be resumed after the Mongols had withdrawn.[14]
