Mongyang or Möngyang (Burmese: မိုးညှင်း|translit=Mohnyin; also known as Mong Yang; Thai: เมืองยาง) was a Shan state in what is today Burma. It was an outlying territory, located away from the main Shan State area in present-day Kachin State. The state existed before 1400 and after 1604. The main town was Mohnyin (Mong Yang).
Möngyang (Mong Yang) was a Shan state established at an uncertain date before the 15th century with the town of Mohnyin as its capital. In 1527 Mongyang armies succeeded in capturing Ava, upsetting the delicate power balance that had existed in the area for nearly two centuries.[1]
A record of the conquest of Mongyang in 1557 is mentioned in a bell inscription relating the conquests of King Bayinnaung.[2] Occupied by the Taungoo dynasty of Burma between 1579 and 1584, the state was extinguished in 1604.[3]
