Mari language
There was no state support for Mari language in Imperial Russia, and with the exception of some enthusiasts and numerous ecclesiastical texts by the Russian Orthodox Church, there was almost no education in Mari language. After the October Revolution, there was a period of support of all lesser national cultures in the Soviet Union, but eventually Russification returned. While the development of Mari literary language continued, still, only elementary-school education was available in Mari in the Soviet period, with this policy ending in village schools in the 1970–1980s. The period of glasnost and perestroika in the 1990s opened opportunities for a revival of efforts expand the use of Mari in education and the public sphere. In the 1990s, the Mari language, alongside Russian, was proclaimed in the republican constitution to be an official language of Mari El. By the beginning of the 21st century, Mari language and literature was taught in 226 schools. At the History and Philology Department of the Mari State University and the Krupskaya Teachers' Training Institute (Yoshkar-Ola), more than half of the subjects are taught in Mari.
