[Academia] This article discusses about my discovery of a Pre-Angkorian inscription, K.1419 and its record of the well-known Suvarnabhumi toponym. Its mainly fascinating news is about the King of Kings Iśānavarman 1 (616-637AD) being mentioned to rule over the surface of Suvarṇṇabhūmi where stretched its border with ocean and contained a lot of vassal kings under his suzerain. Many scholars claim that Suvarnabhumi was fitted with mainland Southeast Asia, Myanmar in 1478 AD and Thailand in the so-called 1292 AD, while another analogue name, Suvarnadvipa was located in the archipelago of this region including Malaysia and Indonesia, according to an inscription of the southern Sumatra in 1286 AD. Hence, they assume this toponym should be covered the Southeast Asian region and warn no one can claim it to be their own since the evidences were scattered in many countries. My analysis is that Suvarnabhumi of all countries of this region wasn't appeared at the same time. It emerged in Pre-Angkor Cambodia in 633 AD and was the oldest one. Other countries were interested in bearing this name respectively because they were believed in Buddhism where is the source of this well-known toponym. Probably, those countries in the ancient time adored it in the sense of being or dedicating as a successive abundance empire of former Cambodian Suvarnabhumi after it was abandoned by next Cambodian leaders. Therefore, scholars and all nationalists in this Southeast Asia shouldn't be confused with its timeline usage.
