According to 7th century Kota Kapur inscription, Srivijaya, centred in today Palembang, South Sumatra, launched a military expedition against "Bhumi Jawa", the period coincides with the decline of Tarumanagara. It is very likely that Tarumanagara kingdom was attacked and defeated by Srivijaya around 686. The pretext behind Srivijayan campaign against Tarumanagara was obscure, however it was probably because of Jayanasa's own claim to Tarumanagara's throne, afterall his wife, Sobakancana, is the daughter of Linggawarman, the late king of Tarumanagara. After this naval invasion, Tarumanegara's influence began to decline.
