The Provisional Priamurye Government or Provisional Priamur Government (Russian: Приамурский земский край) existed in the region of Priamurye of the Russian Far East between May 27, 1921 and June 16, 1923. It was the last Russian State enclave during the Russian Civil War.
Gradually the Priamurye enclave was expanded to Khabarovsk and then to Spassk, 125 miles north of Vladivostok.[1] The Merkulovs were deposed in June 1922 by the Priamurye Zemsky Sobor (Russian: Приамурский Земский Собор) and replaced by one of Admiral Alexander Kolchak's generals, Mikhail Diterikhs.
In July 1922, a Zemsky Sobor (Приамурский Земский Собор) was convened in the territory. This sobor called all Russian people to repent for the overthrow of the Tsar and proclaimed a new Tsar, Grand Duke Nikolai Nikolayevich. Patriarch Tikhon was named as the honorary chairman of the sobor. Neither the Grand Duke nor the Patriarch was present. The territory was renamed Priamursky Zemsky Krai and Diterikhs styled himself voyevoda. The army was renamed the Zemskaya Rat ("Territorial Rat'" - the archaic Slavic term rat' means "military force").
When the Japanese withdrew from the Priamurye (June to October 1922), the Soviet army of the Far Eastern Republic retook most of the Priamurye Government territory. The Ayano-Maysky District was controlled by Anatoly Pepelyayev at that time; its surrender in June 1923 marked the end of the Russian Civil War.
