The Cold War stemmed from war, from the violence, fear and paranoia that conflict fostered, and from defeat and victory in two successive struggles, World War One and the Russian Civil War. Defeat at the hands of Germany and, even more, the social and political strain of conflict on an unprecedented scale in World War One (1914–18) led, in March 1917, to the fall of the Romanov dynasty in Russia and its replacement by a provisional, republican government. The dynasty had responded more successfully to the challenge of the Thirteen Years’ War with Poland in 1654–67, to the Great Northern War with Sweden in 1700–21, to wars with the Turks, Sweden and France between 1806 and 1815, and even to the brief French occupation of Moscow in 1812, than it was to do to war of a very different type with Germany.
multi-sided civil war in the former Russian Empire, November 1917-October 1922
The Russian Civil War (Russian: Гражданская война в России, tr. Grazhdanskaya voyna v Rossii) was a multi-party civil war in the former Russian Empire immediately after the two 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 favouring political monarchism, capitalism and social democracy, each with democratic and anti-democratic variants. In addition, rival militant socialists, notably Makhnovia anarchists and Left SRs, as well as non-ideological Green armies and independence-seeking minority groups, opposed the Reds, the Whites and foreign interventionists. Thirteen foreign nations intervened against the Red Army, notably the former Allied military forces from the just-concluded World War with the goal of re-establishing the Eastern Front. Three foreign nations of the Central Powers also intervened, rivaling the Allied intervention with the main goal of retaining the territory they had received in the Treaty of Brest-Litovsk.
