The Provisional Government of Autonomous Siberia (PGAS), or in full the Social Revolutionary-Menshevik Provisional Government of Autonomous Siberia, was an ephemeral puppet government for Siberia created by the White movement. It came into power on June 29, 1918 during the Bolshevik Revolution after a coup at Vladivostok, and effectively ended with the murder of the White leader Aleksandr Kolchak on February 7, 1920. It was centered in Omsk.
