Ma Thanegi records that the first use of the name 'Mranma' for the country is to be found on a high stone inscription dated 597 ME (Traditional Burmese calendar) or 1235 CE. The stone is from the reign of Kyaswa, (1234-1250) son of King Htilominlo (Nadaungmya), Bagan. It is written in early Burmese script. Although the middle of the front side of this stone is damaged, the first line of the better-protected reverse side clearly shows မြန်မာပြည် ("Mranma kingdom"). The inscription is known as the 'Yadana Kon Htan Inscription'. At present it is in Bagan recorded as stone number 43 in the Archaeological Department's collection.
