Provisional All-Russian Government

The Provisional All-Russian Government (PA-RG) was a short-lived government (1918-1920) centred in Omsk during the Russian Civil War of 1917-1922. It formed from the Komuch (mainly Socialist-Revolutionary Party (SR) and Constitutional Democratic Party (Kadet) members based in Samara) and from the Provisional Siberian Government, which consisted mainly of regional politicians and rightist officers and was based at Omsk. The two régimes had previously failed to work effectively together, with rivalry leading to a customs war and to numerous border disputes.
