FamineA famine is a widespread scarcity of food, caused by several factors including war, natural disasters, crop failure, widespread poverty, an economic catastrophe or government policies. This phenomenon is usually accompanied or followed by regional malnutrition, starvation, epidemic, and increased mortality. Every inhabited continent in the world has experienced a period of famine throughout history. During the 19th and 20th century, Southeast and South Asia, as well as Eastern and Central Europe, suffered the greatest number of fatalities.
Barrier troopsBarrier troops, blocking units, or anti-retreat forces are military units that are located in the rear or on the front line (behind the main forces) to maintain military discipline, prevent the flight of servicemen from the battlefield, capture spies, saboteurs and deserters, and return troops who flee from the battlefield or lag behind their units. According to research by Jason Lyall, barrier troops are more likely to be used by the militaries of states that discriminate against the ethnic groups that comprise the state's military.
Red TerrorThe Red Terror (krasnyj terror) in Soviet Russia was a campaign of political repression and executions which was carried out by the Bolsheviks, chiefly through the Cheka, the Bolshevik secret police. It officially started in early September 1918 and lasted until 1922. Arising after assassination attempts on Vladimir Lenin and Petrograd Cheka leader Moisei Uritsky in retaliation for Bolshevik atrocities, the latter of which was successful, the Red Terror was modeled on the Reign of Terror of the French Revolution, and sought to eliminate political dissent, opposition, and any other threat to Bolshevik power.
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.
Russian RevolutionThe Russian Revolution was a period of political and social change in the Russian Empire, starting in 1917. This period saw Russia abolish its monarchy and adopt a socialist form of government following two successive revolutions and a bloody civil war. The Russian Revolution can also be seen as the precursor for the other European revolutions that occurred during or in the aftermath of World War I, such as the German Revolution of 1918–1919. The Russian Revolution was inaugurated with the February Revolution in early 1917.
Allied intervention in the Russian Civil WarThe Allied intervention in the Russian Civil War consisted of a series of multi-national military expeditions that began in 1918. The initial impetus behind the interventions was to secure munitions and supply depots from falling into the German Empire's hands, particularly after the Bolsheviks signed the Treaty of Brest Litovsk, and to rescue the Allied forces that had become trapped within Russia after the 1917 October Revolution. After the Armistice of 11 November 1918, the Allied plan changed to helping the White forces in the Russian Civil War.
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.
