The Russian All-Military Union is a White movement organization that was founded by White Army General Pyotr Wrangel in the Kingdom of Serbs, Croats and Slovenes on 1 September 1924. It was initially headquartered in the town of Sremski Karlovci. The organization′s ostensible purpose was providing aid to the veterans of the Russian White movement, soldiers and officers alike, who had moved outside the Soviet Union.

The White movement, also known as the Whites, was a loose confederation of anti-communist forces that fought the communist Bolsheviks, also known as the Reds, in the Russian Civil War (1917–1923) and that to a lesser extent continued operating as militarized associations of rebels both outside and within Russian borders in Siberia until roughly World War II (1939–1945). The movement's military arm was the White Army, also known as the White Guard or White Guardsmen.
