Sanin (Russian: Санин ) is a novel by the Russian writer Mikhail Artsybashev.
 It has an interesting history being written by a 26-year-old in 1904 – at the peak of the various changes in Russian society (democratic activities, first democratically elected Duma, as well as the Russian Revolution of 1905).
 It was published and criticized in 1907, the year of one of the most horrific political reactions in Russian history.
 In the early 1900s Russia society was heavily influenced by religions, primarily the Russian Orthodox Church.
 Though there were many other religions such as Uniate Catholics, Judaism, and Muslims, none of them condoned an open expression of sexuality.
 By 1908 the novel was no longer being produced due to censorship.
 It was banned as a "work of pornography" (Otto Boele).
 When Artsybashev emigrated to Poland after the Russian Revolution of 1917, he was condemned by the Soviet authorities and his books were banned from publication, only to be revealed afresh to readers in the 1990s.
The Russian Civil War (Russian: Гражда́нская война́ в Росси́и , "Grazhdanskaya voyna v Rossiyi" ; November 1917 – October 1922) was a multi-party war in the former Russian Empire immediately after the Russian Revolutions of 1917, as many factions vied to determine Russia's political future.
 The two largest combatant groups were the Red Army, fighting for the Bolshevik form of socialism led by Vladimir Lenin, and the loosely allied forces known as the White Army, which included diverse interests favoring monarchism, capitalism and alternative forms of socialism, each with democratic and antidemocratic variants.
 In addition, rival militant socialists and nonideological Green armies fought against both the Bolsheviks and the Whites.
 Eight foreign nations intervened against the Red Army, notably the Allied Forces and the pro-German armies.
 The Red Army defeated the White Armed Forces of South Russia in Ukraine and the army led by Admiral Aleksandr Kolchak in Siberia in 1919.
 The remains of the White forces commanded by Pyotr Nikolayevich Wrangel were beaten in Crimea and evacuated in late 1920.
 Lesser battles of the war continued on the periphery for two more years, and minor skirmishes with the remnants of the White forces in the Far East continued well into 1923.
 The war ended in 1923 in the sense that Red control of the newly formed Soviet Union was now assured, although armed national resistance in Central Asia was not completely crushed until 1934.
 There were an estimated 7,000,000–12,000,000 casualties during the war, mostly civilians.
 The Russian Civil War has been described by some as the greatest national catastrophe that Europe had yet seen.
Territorial changes of the Baltic states refers to the redrawing of borders of Lithuania, Latvia and Estonia after 1940.
 The three republics, formerly autonomous regions within the former Russian Empire and before that of former Polish - Lithuanian Commonwealth, gained independence in the aftermath of World War I and the Russian Revolution of 1917.
 After a two-front independence war fought against both Bolshevist Russian and Baltic German nationalist forces, the countries concluded peace and border treaties with Soviet Russia in 1920.
 However, with World War II and the occupation and annexation of these republics into the Soviet Union twenty years after their independence, certain territorial changes were made in favour of the Russian SFSR.
 This has been the source of political tensions after they regained their independence with the dissolution of the Soviet Union.
 Some of the disputes remain unresolved.
The Russian American Line was a subsidiary steamship line of the East Asiatic Company that was in business from 1900 until the time of the Russian Revolution in 1917.
 In 1906 it began passenger service from Libau to New York after the Hamburg America Line acquired a controlling interest in the line.
 After the Russian Revolution, services ended in 1917.
 Some of the line's ships came under control of the Cunard Line and were operated as troop ships during World War I.
 After the Armistice, most of the line's ships were sold or transferred to the Baltic American Line, another subsidiary of the East Asiatic Company.
Vera Alexandrovna Tiscenko (28 August 1902 – 13 October 1983) was a Russian actress of Polish descent and member of the Moscow Art Theatre who lived through four revolutions: the 1905 Russian Revolution, the Russian Revolution (1917), the Spanish Civil War, the Direct Action Day & Indian Independence Movement, and the Indo-Pakistani War of 1947 (also known as the First Kashmir War).
 In India, her divorce from her first husband, Eugene Tiscenko, has achieved the status of a constitutional precedent that has been deployed repeatedly by the Supreme Court of India.
 She was the second wife of Huseyn Shaheed Suhrawardy who was the last Chief Minister of United Bengal (April 1946- August 1947) and subsequently became the fifth Prime Minister of Pakistan (1956–1957).
Polish Armed Forces in the East around World War I is a term used for several Polish military formations formed in Russia and operating in the period of 1914–1920 (First World War, Russian Revolution of 1917, and the early stages of the Polish-Ukrainian War and Polish-Soviet War.
 Early formations were part of the Imperial Russian Army.
 Later, during the Russian Revolution, the Polish formations were mainly allied to the White Russian forces and the Western powers (both the German Empire and the Entente).
 All the formations (or their remains) were eventually incorporated into the Polish Army by 1920.
HMS "Cardiff" was a C-class light cruiser built for the Royal Navy during World War I.
 She was one of the five ships of the "Ceres" sub-class and spent most of her career as a flagship.
 Assigned to the Grand Fleet during the war, the ship participated in the Second Battle of Heligoland Bight in late 1917.
 "Cardiff" was briefly deployed to the Baltic in late 1918 supporting anti-Bolshevik forces during the British campaign in the Baltic during the Russian Civil War.
The Russian Revolution of 1905 was a wave of mass political and social unrest that spread through vast areas of the Russian Empire, some of which was directed at the government.
 It included worker strikes, peasant unrest, and military mutinies.
 It led to Constitutional Reform including the establishment of the State Duma, the multi-party system, and the Russian Constitution of 1906.
The Russian Expeditionary Force (French: "Corps Expéditionnaire Russe en France" ) was a World War I military force sent to France by the Russian Empire.
 In 1915 the French requested that Russian troops be sent to fight alongside their own army on the Western Front.
 Initially they asked for 300,000 men, an unrealistically high figure, probably based on assumptions about Russia's 'unlimited' reserves. General Mikhail Alekseev, the Imperial Chief of Staff, was opposed to sending any Russian troops, although Nicholas II finally agreed to send a unit of brigade strength.
 The First Russian Special Brigade finally landed at Marseille in April 1916.
 A Second Special Brigade was also sent to serve alongside other Allied formations on the Salonika Front in northern Greece.
 In France, the First Brigade participated in the Nivelle Offensive, however with news of the Russian Revolution of 1917 impacting on the demoralisation within the French Army following the failure of that offensive, the 1st and 3rd Brigades participated in the wave of mutinies spreading across France.
 The First Brigade was finally disbanded before the end of the year.
 However, the "Honorary Russian Legion" (French: "Légion d’Honneur Russe" ) of the 1 Moroccan Division continued to maintain a Russian presence in the west and, indeed in the First World War itself, until the Armistice of 11 November 1918.
205 Signal Squadron was a unit of the Royal Corps of Signals of the British Army.
 After two of their members were killed in an Army Air Corps Gazelle helicopter due to a friendly fire incident with HMS Cardiff during the Falklands War, the numbers "205" were painted at the crash site as a memorial.
