Upon the death of Stalin in 1953, the lyrics, which mentioned him by name, were discarded during the process of de-Stalinization and the anthem continued to be used without words. Mikhalkov wrote new lyrics in 1970, but they were not submitted to the Presidium of the Supreme Soviet until May 27, 1977. The new lyrics, which removed any reference to Stalin, were approved on September 1 and were made official with the printing of the new Soviet Constitution in October 1977.
