Burmese chronicles
Myanmar possesses the largest number of historical stone inscriptions as well as most complete historical records in all of Southeast Asia. The first systematic effort to preserve the inscriptions was launched by King Bodawpaya per the royal order dated 23 July 1783 to check then existing chronicles with inscriptional evidence. By 1793, over 600 inscriptions from throughout the country were copied (recast), and kept at the capital Amarapura. European scholars in the British colonial period greatly expanded the collection effort, with a 1921 edition of "Epigraphia Birmanica" by Charles Duroiselle listing some 1500 inscriptions in original spelling and a large photograph of each text. The most complete set of inscriptions, called "She-haung Myanma Kyauksa Mya" (; lit. "Ancient Inscriptions of Myanmar") was only recently published by Yangon University's Department of Archaeology in five volumes from 1972 to 1987. Aside from over 500 Pagan period inscriptions, most of the other stone inscriptions have not been studied systematically.
