Rurik dynasty in the context of "Varangians"

Kievan Rus', also known as Kyivan Rus', was the first East Slavic state and later an amalgam of principalities in Eastern Europe from the late 9th to the mid-13th century. Encompassing a variety of polities and peoples, including East Slavic, Norse, and Finnic, it was ruled by the Rurik dynasty, founded by the Varangian prince Rurik. The name was coined by Russian historians in the 19th century to describe the period when Kiev was preeminent. At its greatest extent in the mid-11th century, Kievan Rus' stretched from the White Sea in the north to the Black Sea in the south and from the headwaters of the Vistula in the west to the Taman Peninsula in the east, uniting the East Slavic tribes.

According to the Primary Chronicle, the first ruler to unite East Slavic lands into what would become Kievan Rus' was Varangian prince Oleg the Wise (r. 879–912). He extended his control from Novgorod south along the Dnieper river valley to protect trade from Khazar incursions from the east, and took control of the city of Kiev, laying the foundation of the state and becoming prince of Kiev. Sviatoslav I (r. 943–972) achieved the first major territorial expansion of the state, fighting a war of conquest against the Khazars. Vladimir the Great (r. 980–1015) spread Christianity with his own baptism and, by decree, extended it to all inhabitants of Kiev and beyond. Kievan Rus' reached its greatest extent under Yaroslav the Wise (r. 1019–1054); his sons assembled and issued its first written legal code, the Russkaya Pravda, shortly after his death.

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.

Rurik (also spelled Rorik, Riurik or Ryurik; Church Slavonic: Рюрикъ, romanized: Rjurikŭ; Old Norse: Hrøríkʀ; died 879) was a Varangian chieftain of the Rus' who, according to tradition, was invited to reign in Novgorod in the year 862. The Primary Chronicle states that Rurik was succeeded by his kinsman Oleg who was regent for his infant son Igor.

Traditionally, Rurik has been considered the founder of the Rurik dynasty, which was the ruling dynasty of Kievan Rus' and its principalities, and ultimately the Tsardom of Russia, until the death of Feodor I in 1598. As a result, he is considered to be the traditional founder of the Russian monarchy.

The House of Romanov (also transliterated as Romanoff. Russian: Романовы, romanized: Romanovy, IPA: [rɐˈmanəvɨ]) was the reigning imperial house of Russia from 1613 to 1917. They achieved prominence after Anastasia Romanovna married Ivan the Terrible, the first crowned tsar of all Russia. Nicholas II, the last Emperor of Russia, and his immediate family were executed in 1918, but there are still living descendants of other members of the imperial house.

The house consisted of boyars in Russia (the highest rank in the Russian nobility at the time) under the reigning Rurik dynasty, which became extinct upon the death of Feodor I in 1598. The Time of Troubles, caused by the resulting succession crisis, saw several pretenders and imposters lay claim to the Russian throne during the Polish-Lithuanian occupation. On 21 February 1613, the Zemsky Sobor elected Michael Romanov as tsar, establishing the Romanovs as Russia's second reigning dynasty.
