Arunāsva (also known as Aluonashun by the Chinese and as Arjuna[1]) was the ruler of the Kingdom of Kannauj,[2] and prior to this the governor of Tirabhukti.
He had been the governor of Tirhut and a minister at the court of Harsha and usurped the throne after his death, succeeding the Pushyabhuti dynasty.
[4] The historian, Yogendra Mishra, was of the view that Arunasva was likely a prince related to the Maukhari dynasty who had established a base of operations for himself in the region of Tirhut where he served as a governor for Harshavardhana.
However once in India he discovered Harsha had died and the new king Aluonashun (supposedly Arunāsva) attacked Wang and his 30 mounted subordinates.
(Note that this is not a prestigious title, only in the 5th rank of Tang's nine-rank official system) [7] He also secured a reported Buddhist relic for China.
