Zemsky Sobor
The "Zemsky Sobor of Amur region" (Приамурский Земский Собор) of the Provisional Priamurye Government was convened in Vladivostok on July 23, 1922 by Mikhail Diterikhs during the Russian Civil War. Diterikhs was a general of the White Army in the Russian Far East and convened the assembly four years after the execution of the Romanov family to proclaim a new monarchy, naming Grand Duke Nicholas Nikolaevich as the Tsar of Russia, with Patriarch Tikhon as the honorary chairman of the Zemsky Sobor. Neither Nikolai or Tikhon were present at the assembly, and the plan was cancelled when the region fell to the Bolsheviks two months later.
