Sailendra Dynasty

The Shailendra dynasty (IAST: Śailēndra derived from Sanskrit combined words Śaila and Indra, meaning "King of the Mountain", also spelled Sailendra, Syailendra or Selendra) was the name of a notable Indonesian dynasty that emerged in 8th century Java whose reign marked a cultural renaissance in the region. The Shailendras were active promoters of Mahayana Buddhism and covered the Kedu Plain of Central Java with Buddhist monuments, one of which is the colossal stupa of Borobudur, now a UNESCO World Heritage Site.

The Shailendras are considered to be a thalassocracy and ruled maritime Southeast Asia, however they also relied on agriculture pursuits through intensive rice cultivation on the Kedu Plain of Central Java. The dynasty appeared to be the ruling family of both the Medang Kingdom of Central Java for some period and Srivijaya in Sumatra.

The inscriptions created by Shailendras uses three languages; Old Malay, Old Javanese and Sanskrit, written either in the Kawi alphabet or pre-Nāgarī script. The use of Old Malay has sparked the speculation of a Sumatran origin or Srivijayan connection of this family; on the other hand, the use of Old Javanese suggests their firm political establishment on Java. The use of Sanskrit usually signifies the official nature and religious significance of the event written on the inscription.
