The traditional Mongolian alphabet is not a perfect fit for the Mongolian language, and it would be impractical to extend it to a language with a very different phonology like Chinese. Therefore, during the [[Yuan dynasty]] ({{circa|1269}}), [[Kublai Khan]] asked a Tibetan monk, [[Drogön Chögyal Phagpa]], to design a new script for use by the whole empire. Phagpa extended his native [[Tibetan script]] to encompass Mongolian and Chinese; the result was known by several descriptive names, such as the ''Mongolian new script'', but today is known as the 'Phags-pa script. The script did not receive wide acceptance and fell into disuse with the collapse of the Yuan dynasty in 1368. After this it was mainly used as a phonetic [[interlinear gloss|gloss]] for Mongols learning Chinese characters. However, scholars such as [[Gari Ledyard]] believe that in the meantime it was the source of some of the basic letters of the Korean [[hangul]] alphabet.
