In the People's Republic of China, Mongolian is a co-official language with Mandarin Chinese in some regions, notably the entire Inner Mongolia Autonomous Region. The traditional alphabet has always been used there,
Modern Mongolian evolved from Middle Mongol, the language spoken in the Mongol Empire of the 13th and 14th centuries. IMongolian is distantly related to the Khitan language. It belongs to the Northern Asian linguistic area including the Turkic, Mongolic, Tungusic, Korean and Japonic languages.
The classical Mongolian script, sister to The Old Uyghur alphabet, was the first writing system created specifically for the Mongolian language, and was the most successful until the introduction of Cyrillic in 1946. Derived from Sogdian, Mongolian is a true alphabet, with separate letters for consonants and vowels.
