Karelian language
On September 8, 1937, at the proposal of its chairman, M.I. Kalinin, the Presidium of the Central Executive Committee discussed the Cyrillization of the Karelian language. The final orthography was approved by the Karelian Regional Committee on February 10, 1938 and published in the newspaper "Karel'skaya Pravda". On February 14, the RSFSR People's Commissariat issued decree no. 214, introducing the single Karelian language in the Cyrillic alphabet.
