Dharanindra or commonly known as King Indra was the ruler of the Sailendra dynasty who was the Emperor of Mataram in Central Java and Srivijaya in South Sumatera.
The similar title also found in Ligor B inscription discovered in Southern Thailand Malay Peninsula; Sarwwarimadawimathana, which suggest it referred to the same person.
Dharanindra seems to be a warlike character, as he embarked on military naval expedition overseas and has brought Sailendras' control on Ligor in Malay Peninsula.
At the behest of Maharaja of Srivijaya (Dharaindra), Jayavarman II was installed as a new Cambodia king and Angkor Dynasty was founded.
He was also probably responsible for the conception, planning and initial phase of construction of Borobudur and Pawon temple.
