On May 26, 1921, with the overthrow of the government of the Primorskaya Zemsky Administration headed by the Bolshevik Vasily Antonov in Vladivostok by the white rebels, the Priamurye State Formation was established. Power was soon transferred to the Congress of Non–Socialist Organizations of the Far East, which elected a Provisional Amur Government. In a matter of days, the Provisional Amur government established its own armed forces, which were based on units of the Far Eastern Army, which were previously part of the armies of General Vladimir Kappel and Ataman Grigory Semyonov. The United States of America and Japan provided comprehensive support to the new state formation, while the latter also provided military assistance at the expense of the Japanese troops stationed in Primorye during the intervention. General Grigory Verzhbitsky was appointed commander–in–chief of the armed forces on May 31, 1921. At that moment, for the first time in Russian historiography, the name White Rebel Army appeared, parts of which became the basis of the formed armed forces. Major General Viktorin Molchanov became the head of the army, partially assembled from the units of the Grodekov group of forces (later – the 2nd Corps of General Innokenty Smolin). Officially, the existence of the army was recognized only in November 1921.
