Kalmykia is one of the national republics of the Russian Federation. It is a multinational republic: representatives of more than 90 nationalities live here, of which Kalmyks constitute more than 50%. Kalmyks are also known as Oirats, western Mongols, and European Mongols. The 20th of August, 1609 is the official date of the free will entry of Kalmyks into Russia. The most tragic event in the history of Kalmyks happened in January of 1771, when Ubashi Kalmyks (according to data 70%) back to Djungaria. On the 19th of October 1771 the Kalmyk Khanate was eliminated. The Kalmyk state organization was again returned in 1920, when the Decree of Kalmyk Autonomy was signed. However, in December of 1943 the Kalmyk Republic was eliminated and all Kalmyks were exiled to Siberia. Only after the 20th Party Congress (in 1956) Kalmyks were rehabilitated and the Republic was restored. The song and dance folklore of Kalmyks is original. It differs Kalmyks from related peoples (Buryats, Khalkha, Mongols of Inner Mongolia), for the influence of the Caucasus, the Tartar and the Russian cultures is displayed. The situation of the Kalmyk language nowadays is very dangerous, as the deportation of Kalmyks to Siberia affected the language badly. Kalmyk is a language of the agglutination type. As far as its origin is concerned the Kalmyk language belongs to the west Mongolian subgroup (Mongolian language group, Altai language family). Isolated development of Kalmyk and absence of close connections with the related languages resulted in archaization of some linguistic features and formation of the synthetic forms out of analytical ones. Kalmyk people have a large written tradition. Till 1924, before changing to the Cyrillic alphabet, they used Oirat written language, created by the Oirat enlightener Zaya Pandit. There is a big written inheritance in Oirat in libraries around Russia.
