republic of Russia

The republics are one type of federal subject of the Russian Federation. Twenty-one republics are internationally recognized as part of Russia; another is under its de facto control. The original republics were created as nation states for ethnic minorities. The indigenous ethnicity that gives its name to the republic is called the titular nationality. However, due to centuries of Russian migration, a titular nationality may not be a majority of its republic's population. By 2017, the autonomous status of all republics was formally abolished, making the republics politically equivalent to the other federal subjects of Russia.

Formed in the early 20th century by Vladimir Lenin and the Bolsheviks after the collapse of the Russian Empire in 1917, republics were intended to be nominally independent regions of Soviet Russia with the right to self-determination. Lenin's conciliatory stance towards Russia's minorities made them allies in the Russian Civil War and with the creation of the Soviet Union in 1922 the regions became autonomous republics, albeit subordinate to a union republic. While officially autonomous, the autonomies of these administrative units varied throughout the history of the Soviet Union but largely remained under the control of the central government. The 1980s saw an increase in the demand of autonomy as the Soviet Union began large scale reforms of its centralized system. In 1990, most of the autonomous republics declared their sovereignty. The Soviet Union collapsed in 1991 and Russia became independent. The current republics were established with the signing of the Federation Treaty in 1992, which gave them substantial rights and autonomy.
