The Mordovian Autonomous Soviet Socialist Republic was established on December 20, 1934 by the transformation from of
Kuybyshev Krai. After Kuybyshev Krai was itself transformed into
Kuybyshev Oblast, the Mordovian ASSR was separated from it and subordinated to the
Russian Soviet Federative Socialist Republic. On December 7, 1990, the Supreme Soviet of the Mordovian ASSR adopted the Declaration on the legal status of the Mordovian Republic, which transformed the republic into the Mordovian Soviet Socialist Republic. The republic was renamed the Republic of Mordovia on January 25, 1994. ==See also==
