Varangian in the context of "Oleg of Novgorod"

Vladimir I Sviatoslavich or Volodymyr I Sviatoslavych (Old East Slavic: Володимѣръ Свѧтославичь, romanized: Volodiměr Svętoslavič; Christian name: Basil; c. 958 – 15 July 1015), given the epithet "the Great", was Prince of Novgorod from 970 and Grand Prince of Kiev from 978 until his death in 1015. The Catholic Church and the Eastern Orthodox Church both canonised him as Saint Vladimir.

Vladimir's father was Sviatoslav I of the Rurik dynasty. After the death of his father in 972, Vladimir, who was then the prince of Novgorod, was forced to flee abroad after his brother Yaropolk murdered his other brother Oleg in 977 to become the sole ruler of Rus'. Vladimir assembled a Varangian army and returned to depose Yaropolk in 978. By 980, Vladimir had consolidated his realm to the Baltic Sea and 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.

The Rurik dynasty, also known as the Rurikid or Riurikid dynasty, as well as simply Rurikids or Riurikids, was a noble lineage allegedly founded by the Varangian prince Rurik, who, according to tradition, established himself at Novgorod in the year 862. The Rurikids were the ruling dynasty of Kievan Rus' and its principalities following its disintegration.

The Romanovichi ruled the southwestern territories, which were unified by Roman the Great and his son Daniel, who was in 1253 crowned by Pope Innocent IV as the king of Ruthenia. Galicia–Volhynia was eventually annexed by Poland and Lithuania. The northern and northeastern territories were unified by the Daniilovichi of Moscow; by the 15th century, Ivan III threw off the control of the Golden Horde and assumed the title of sovereign of all Russia. Ivan IV was crowned as the tsar of all Russia, where the Rurik line ruled until 1598, following which they were eventually succeeded by the House of Romanov.

Gnezdovo or Gnyozdovo (Russian: Гнёздово) is an archeological site located near the village of Gnyozdovo in Smolensky District, Smolensk Oblast, Russia. The site contains extensive remains of a Slavic-Varangian settlement that flourished in the 10th century as a major trade station on the trade route from the Varangians to the Greeks.

The Varangian Guard (Greek: Τάγμα τῶν Βαράγγων, romanized: Tágma tōn Varángōn) was an elite unit of the Byzantine army from the 10th to the 14th century who served as personal bodyguards to the Byzantine emperors. The Varangian Guard was known for being primarily composed of recruits from Northern Europe, including mainly Norsemen from Scandinavia but also Anglo-Saxons from England. The recruitment of distant fighters from outside Byzantium to serve as the emperor's personal guard was pursued as a deliberate policy, as they lacked local political loyalties and could be counted upon to suppress revolts by disloyal Byzantine factions.

The Rus' provided the earliest members of the Varangian Guard. They were in Byzantine service from as early as 874. The Guard was first formally constituted under Emperor Basil II in 988, following the Christianization of Kievan Rus' by Vladimir I of Kiev. Vladimir, who had recently taken control of Kiev with an army of Varangian warriors, sent 6,000 men to Basil as part of a military assistance agreement. Basil's distrust of the native Byzantine guardsmen, whose loyalties often shifted with fatal consequences, as well as the proven loyalty of the Varangians, many of whom had previously served in Byzantium, led the Emperor to employ them as his personal guardsmen.
