Kievan Rus'
Also known as Kievan Rus, Kyivan Rus, Rus' Khaganate, Principality of Kyiv
Kievan Rus grew from settlements of Scandinavian traders and warriors, known as the Rus or Varangians, along the river routes linking the Baltic to the Black Sea and Byzantium. According to the Primary Chronicle, Oleg of Novgorod seized Kyiv in 882 and made it his capital, ruling over East Slavic, Finnic and Baltic peoples.
The Rurikid princes collected tribute in furs and slaves and traded with Constantinople, which they also raided. In 988 Vladimir the Great accepted Orthodox Christianity from Byzantium, and his son Yaroslav the Wise issued a law code and built St Sophia's Cathedral. After 1054 the realm fragmented into rival principalities ruled by branches of the dynasty. The Mongol invasion destroyed it, and Kyiv was sacked in 1240.
