Ligdan Khan
Classical Mongolian was the literary language of Mongolian which was first introduced shortly after 1600, when Ligdan Khan set his clergy the task of translating the whole of the Tibetan Buddhist canon, consisting of the Kanjur and Tanjur, into Mongolian. This script then became the established literary language used for all Mongolian literature since its introduction, until the 1930s when the Mongolian Latin script was established, which then in 1941 was replaced by the Mongolian Cyrillic script.
