Short answers, pulled from the story.
The term White carried three distinct meanings that shaped a movement fighting to restore order. Some observers linked the term to the French Revolution where forces opposing the revolution and supporting the Bourbon monarchy used white as their symbolic color. Others traced the name to historical references of absolute monarchy specifically recalling Russia's first Tsar Ivan III who reigned from 1462 to 1505.
The main force behind the White movement consisted of conservative officers from the Russian Empire who shared a common military culture. Admiral Alexander Kolchak headed the eastern White Army while Anton Denikin took command of the Armed Forces of the South of Russia in January 1919 after Lavr Kornilov died in April 1918. Pyotr Wrangel later led remnants of the Volunteer Army that evacuated from Novorossiysk to Crimea on March 26 and 27, 1920.
The Whites fought the Russian Civil War from November 1917 until 1921 across three main theaters of operation. Isolated battles continued in the Far East until June 1923 when Anatoly Pepelyayev controlled the Ayano-Maysky District. The Eastern Front started in spring 1918 as a secret movement among army officers and right-wing socialist forces.
Racial antisemitism was widespread in the army and in Russian society during the Civil War period because Jews could not become army officers and were mistreated due to beliefs about subversive ideologies. The propaganda service of the Volunteer Army claimed that Jews must pay for everything including the February and October revolutions while White Orthodox Christian priests denounced Jews as Christ-killers. Some soldiers even received bonuses for their actions despite warnings from Winston Churchill to General Anton Denikin.
Defeated anti-Bolshevik Russians went into exile congregating in cities like Belgrade Berlin Paris Harbin Istanbul and Shanghai. They established military and cultural networks that lasted through World War II which ran from 1939 to 1945. This community endured within wider White émigré overseas communities until the dissolution of the Soviet Union in 1990, 1991.
