The Soviet Union's war against Nazi Germany became known as the Great Patriotic War, recalling the previous use of the term in the Napoleonic Wars, the Patriotic War. The Soviet state called for its citizens to defend the "Motherland"; Stalin proclaimed the slogan "Not a step back!". At the same time, Nazi Germany organised collaborationist military units such as Andrey Vlasov's Russian Liberation Army and Pyotr Krasnov's Cossacks. During the Second World War, the strong patriotism of Vlasov's army presented Russians with an alternative to the state-centered nationalism promoted by Stalin's government. In 1944, the Soviet Union abandoned its communist anthem The Internationale and adopted new national anthem.
