Jasminum sambac
The earliest historical events documented by the evidence recovered at Mỹ Sơn relate to the era of King Bhadravarman I (literally "Blessed armour" but also meaning the "Jasminum sambac" flower; ), who ruled from 380 until 413, and who spent the latter part of his reign waging war against the population of Chinese-occupied northern Vietnam. At Mỹ Sơn, Bhadravarman built a hall containing a lingam to worship Shiva under the Sanskrit name "Bhadreśvara" "Blessed Lord", a composite created from the king's own name and the word "īśvara" "lord" commonly used to refer to Shiva.
