SiberiaSiberia (saɪˈbɪəriə ; Sibir', sjɪˈbjirj) is an extensive geographical region comprising all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has formed part of the sovereign territory of Russia and its various predecessor states since the centuries-long conquest of Siberia, which began with the fall of the Khanate of Sibir in the late 16th century and concluded with the annexation of Chukotka in 1778. Siberia is vast and sparsely populated, covering an area of over , but home to only one-fifth of Russia's population.
Russian EmpireThe Russian Empire, also known as Imperial Russia, was the final period of the Russian monarchy from its proclamation in November 1721, until its dissolution in late 1917. It consisted of most of northern Eurasia. The Empire succeeded the Tsardom of Russia following the Treaty of Nystad. The rise of the Russian Empire coincided with the decline of neighbouring rival powers: the Swedish Empire, the Polish–Lithuanian Commonwealth, Qajar Iran, the Ottoman Empire, and Qing China.
Ural MountainsThe Ural Mountains (ˈjʊərəl ; Уральские горы) or simply the Urals, is a mountain range in Eurasia that runs north-south mostly through Russia, from the coast of the Arctic Ocean to the river Ural and northwestern Kazakhstan. The mountain range forms part of the conventional boundary between the continents of Europe and Asia. Vaygach Island and the islands of Novaya Zemlya form a further continuation of the chain to the north into the Arctic Ocean. The average altitudes of the Urals are around , the highest point being Mount Narodnaya, which reaches a height of .
February RevolutionThe February Revolution (Февра́льская револю́ция), known in Soviet historiography as the February Bourgeois Democratic Revolution and sometimes as the March Revolution, was the first of two revolutions which took place in Russia in 1917. The main events of the revolution took place in and near Petrograd (present-day Saint Petersburg), the then-capital of Russia, where long-standing discontent with the monarchy erupted into mass protests against food rationing on 23 February Old Style (8 March New Style).
House of RomanovThe House of Romanov (also transliterated Romanoff; Romanovy) was the reigning imperial house of Russia from 1613 to 1917. They achieved prominence after the Tsarina, Anastasia Romanovna, was married to the First Tsar of Russia, Ivan the Terrible. Tsar Nicholas II and his immediate family were executed in 1918, but there are still living descendants. The house became boyars (the highest rank in Russian nobility) of the Grand Duchy of Moscow and later of the Tsardom of Russia under the reigning Rurik dynasty, which became extinct upon the death of Tsar Feodor I in 1598.
White movementThe White movement (pre–1918 Бѣлое движеніе / post–1918 Белое движение) also known as the Whites (Бѣлые / Белые, Beliye), was a loose confederation of anti-communist forces that fought the communist Bolsheviks, also known as the Reds, in the Russian Civil War () and that to a lesser extent continued operating as militarized associations of rebels both outside and within Russian borders in Siberia until roughly World War II (1939–1945).
