Russia profile - Timeline
A chronology of key events:
9th century - Founding of Kievan Rus, the first major East Slavic state. The traditional account, a matter of debate among historians, attributes its founding to the semi-legendary Viking (or Varangian) leader Oleg, ruler of Novgorod, who went on to seize Kiev, which owing to its strategic location on the Dnieper River, became the capital of Kievan Rus.
10th century - Rurik dynasty established and the rule of Prince Vladimir the Great (Prince Volodymyr in Ukrainian) heralds start of a golden age. In 988 Vladimir accepts Orthodox Christianity and begins conversion of Kievan Rus to the Byzantine rite, thus setting the course for Christianity in the east.
11th century - Kievan Rus reaches its peak under Yaroslav the Wise (grand prince 1019-1054), with Kiev becoming eastern Europe's chief political and cultural centre.

14th century - Ascendancy of grand princes of Moscow (or Muscovy) under the Mongols. Ivan I is granted the title of Grand Prince after helping to defeat an anti-Tatar uprising in the principality of Tver, Moscow's great rival.
