The Siberian Intervention (?????? - Shiberia Shuppei); or the Siberian Expedition of 1918-1922 was the dispatch of troops of the Entente powers to the Russian Maritime Provinces as part of a larger effort by the western powers and Japan to support White Russian forces against the Bolshevik Red Army in the final year of World War I and during the Russian Civil War.

The Imperial Japanese Army continued to occupy Siberia even after other Allied forces had withdrawn in 1920. Pictures From History
