The Mongolian Cyrillic script was the result of the spreading of Russian influence following the expansion of Russian Empire. The establishment of Soviet Union helped the influence persisted, and the Cyrillic alphabet was slowly introduced with the effort by Russian/Soviet linguists in collaboration with their Mongolian counterparts. It was made mandatory by government decree in 1941. It has been argued that the introduction of the Cyrillic script, with its smaller discrepancy between written and spoken form, contributed to the success of the large-scale government literacy campaign, which increased the literacy rate from 17.3% to 73.5% between 1941 and 1950. Earlier government campaigns to eradicate illiteracy, employing the traditional script, had only managed to raise literacy from 3.0% to 17.3% between 1921 and 1940. From 1991 to 1994, an attempt at reintroducing the traditional alphabet failed in the face of popular resistance. In informal contexts of electronic text production, the use of the Latin alphabet is common.
