A loose confederation of anti-Bolshevik forces aligned against the Communist government, including landowners, republicans, conservatives, middle-class citizens, reactionaries, pro-monarchists, liberals, army generals, non-Bolshevik socialists who still had grievances and democratic reformists voluntarily united only in their opposition to Bolshevik rule. Their military forces, bolstered by forced conscriptions and terror as well as foreign influence, under the leadership of General Nikolai Yudenich, Admiral Alexander Kolchak and General Anton Denikin, became known as the White movement (sometimes referred to as the "White Army") and controlled significant parts of the former Russian Empire for most of the war.
