Red Army Captures Mongolia

Date: July 11, 1921 • Location: Moscow, Russia

This milestone marked the outbreak and beginning of this historic period, which spanned 1921.

The Red Army captures Mongolia from the White Army and establishes the Mongolian People's Republic.

The Workers' and Peasants' Red Army, often referred by its shortened name as the Red Army, was the army and air force of the Russian Soviet Republic and, from 1922, the Soviet Union. The army was established in January 1918 by a decree of the Council of People's Commissars to oppose the military forces of the new nation's adversaries during the Russian Civil War, especially the various groups collectively known as the White Army. In February 1946, the Red Army was renamed the "Soviet Army". Following the dissolution of the Soviet Union, it was split between the post-Soviet states, with its bulk becoming the Russian Ground Forces, commonly considered to be the successor of the Soviet Army.
