OkhranaThe Department for Protecting the Public Security and Order (Отделение по охранению общественной безопасности и порядка), usually called the Guard Department (Охранное отделение) and commonly abbreviated in modern English sources as the Okhrana (Охрана) was a secret-police force of the Russian Empire and part of the police department of the Ministry of Internal Affairs (MVD) in the late 19th century and early 20th century, aided by the Special Corps of Gendarmes.
ChekaThe All-Russian Extraordinary Commission (AREOC; Всероссийская чрезвычайная комиссия), abbreviated as VČK (ВЧК), and commonly known as Cheka (Чека; from the initialism ChK), was the first of a succession of Soviet secret-police organizations. Established on December 5 (Old Style) 1917 by the Sovnarkom, it came under the leadership of Felix Dzerzhinsky, a Polish aristocrat-turned-Bolshevik. By late 1918, hundreds of Cheka committees had sprung up in the Russian SFSR at all levels.
Russian Civil WarThe Russian Civil War (Grazhdanskaya voyna v Rossii; 7 November 1917 — 16 June 1923) was a multi-party civil war in the former Russian Empire sparked by the overthrowing of the social-democratic Russian Provisional Government in the October Revolution, as many factions vied to determine Russia's political future. It resulted in the formation of the Russian Socialist Federative Soviet Republic and later the Union of Soviet Socialist Republics in most of its territory.
October RevolutionThe October Revolution, known in Soviet historiography as the Great October Socialist Revolution, was a revolution in Russia led by the Bolshevik Party of Vladimir Lenin that was a key moment in the larger Russian Revolution of 1917–1923. It was the second revolutionary change of government in Russia in 1917. It took place through an armed insurrection in Petrograd (now Saint Petersburg) on . It was the precipitating event of the Russian Civil War.
CossacksThe Cossacks are a predominantly East Slavic Orthodox Christian people originating in the Pontic–Caspian steppe of Ukraine and southern Russia. Historically, they were a semi-nomadic and semi-militarized people, who, while under the nominal suzerainty of various Eastern European states at the time, were allowed a great degree of self-governance in exchange for military service. Although numerous linguistic and religious groups came together to form the Cossacks, most of them coalesced and became East Slavic-speaking Orthodox Christians.
BolsheviksThe Bolsheviks (Большевики́, from большинство́ boľšinstvó, 'majority') were a far-left, revolutionary Marxist faction founded by Vladimir Lenin that split with the Mensheviks from the Marxist Russian Social Democratic Labour Party (RSDLP), a revolutionary socialist political party formed in 1898, at its Second Party Congress in 1903. After forming their own party in 1912, the Bolsheviks took power during the October Revolution in the Russian Republic in November 1917, overthrowing the Provisional Government of Alexander Kerensky, and became the only ruling party in the subsequent Soviet Russia and later the Soviet Union.
Chinese in the Russian Revolution and in the Russian Civil WarThere are a number of reports about the involvement of Chinese detachments in the Russian Revolution and Russian Civil War. Chinese served as bodyguards of Bolshevik functionaries, served in the Cheka, and even formed complete regiments of the Red Army. It has been estimated that there were tens of thousands of Chinese troops in the Red Army, and they were among the few groups of foreigners fighting for the Red Army.
