Kievan Rus went faster than other European states and with them. Slavic Sea from the White Lake to the Black Sea and up to the German borders... The authority that Russia had in the pre-Mongol period, we will return only after 500 years under Peter I. Yaroslav the Wise saved Olaf of Norway and raised his son Magnus, the future king of Denmark and Norway. Under his protection in Kyiv was the English prince Edward the Exile. Busy with worldly chores and simple dreams, the Orthodox sea expanded, swaying in measure in warmth and comfort. No one noticed how the advanced Mongolian tumen appeared on the border river Voronezh in December 1237. Horsemen of the Apocalypse, heralding the end of time and darkness for hundreds of years.
