Provisional Siberian Government (Omsk)

Provisional Siberian Government - government for Siberia created by the White movement.

History
At the beginning of 1918 a Provisional Siberian Government (PSG) was established in the eastern coastal city of Vladivostok. Most of the members of this first Siberian provisional government were members of the Socialist-Revolutionary Party (PSR), including the head of this government, Pëtr Derber.

In June 1918, Bolshevik forces in central Siberia were overthrown by the Czechoslovak Legions and Monarchist Russian officers organizations. The ultra-conservative and nationalist Russian officers considered the Socialist-Revolutionary Party to be virtually identical to the hated Bolsheviks and thus sought to install a new regime closer to their own political orientation. On 30 June 1918 a meeting was convened to establish such a new regime. Chairman of the Council of Ministers of this new government was Pëtr Vologodskii.

The Derber government in Vladivostok refused to recognize the legitimacy of this new government based in Omsk. A reorganization of the Vladivostok government followed, with the name Provisional Government of Autonomous Siberia (PGAS) adopted.

The PGAS in Vladivostok and new PSG in Omsk refused to recognize the other, and each claimed for themselves the mantle as sole government of Siberia. The generals of the Siberian Army placed their allegiance with the Vologodskii government in Omsk, however, leading to the marginalization of the Vladivostok regime.

In September 1918 the Provisional Siberian Government became a part of Provisional All-Russian Government.
