Vladimir the Great

Vladimir I Sviatoslavich or Volodymyr I Sviatoslavych (Old East Slavic: Володимѣръ Свѧтославичь, Volodiměrъ Svętoslavičь; c. 958 – 15 July 1015), also known as Vladimir the Great or Volodymyr the Great, was Prince of Novgorod, Grand Prince of Kiev, and ruler of Kievan Rus' from 980 to 1015. Volodymyr's father was Prince Sviatoslav I of Kiev of the Rurikid dynasty. After the death of his father in 972, Vladimir, who was then prince of Novgorod, was forced to flee to Scandinavia in 976 after his brother Yaropolk murdered his other brother Oleg of Drelinia, becoming the sole ruler of Rus'. In Sweden, with the help of his relative Ladejarl Håkon Sigurdsson, ruler of Norway, he assembled a Varangian army and reconquered Novgorod from Yaropolk.[12] By 980, Vladimir had consolidated the Rus realm from modern-day Belarus, Russia and Ukraine to the Baltic Sea and had solidified the frontiers against incursions of Bulgarians, Baltic tribes and Eastern nomads. Originally a follower of Slavic paganism, Vladimir converted to Christianity in 988 and Christianized the Kievan Rus'. He is thus also known as Saint Volodymyr.
