Yaroslav the Wise Monarch

Yaroslav I, Grand Prince of Rus', known as Yaroslav the Wise or Iaroslav the Wise (Old East Slavic: Ꙗрославъ Володимировичъ Мѫдрꙑи, Jaroslavŭ Volodimirovičŭ Mǫdryi; Old Norse: Jarizleifr; Russian: Ярослав Мудрый, Yaroslav Mudry; Ukrainian: Ярослав Мудрий; c. 978 – 20 February 1054) was thrice Grand Prince of Novgorod and Kiev, uniting the two principalities for a time under his rule. Yaroslav's Christian name was George (Yuri) after Saint George (Old East Slavic: Гюрьгi, Gjurĭgì).A son of the Varangian (Viking) Grand Prince Vladimir the Great, he was vice-regent of Novgorod at the time of his father’s death in 1015. Subsequently, his eldest surviving brother, Svyatopolk the Accursed, killed three of his other brothers and seized power in Kiev. Yaroslav, with the active support of the Novgorodians and the help of Varangian mercenaries, defeated Svyatopolk and became the Grand Prince of Kiev in 1019. Under Yaroslav the codification of legal customs and princely enactments was begun, and this work served as the basis for a law code called the Russkaya Pravda ("Rus Truth [Law]"). During his lengthy reign, Rus' reached the zenith of its cultural flowering and military power.
