Who is Balaputra?
Balaputra was the maharaja of Srivijaya in the 9th century CE as well as the former head of the Sailendra dynasty. He was the youngest son of the preceding Sailendran maharaja, Samaratunga, through marriage with Dewi Tara who was in turn the daughter of another maharaja, Dharmasetu of Srivijaya.
Samaratunga died when Balaputra was a boy. As a young heir to the throne, his authority in Central Java was frequently challenged by local landlords. An extended family member by the name of Garung forced Balaputra to accept his tutorship. Garung was part of the Sanjaya Dynasty and was related to Balaputra through marriage of Garung's son, Rakai Pikatan to Pramodhawardhani, Balaputra's sister. During the regency of Garung, the Java political landscape was relatively peaceful. The regency ended in 832 when Garung disappeared.
Around 852, Rakai Pikatan of Sanjaya began garnering influence from the local nobles. This worried Balaputra and he tried to suppress Rakai Pikatan in order to regain control. His effort failed miserably however due to his inexperience and the Sailendras were eventually forced to leave Java for Palembang, the seat of Srivijaya as well as the home of Balaputra's mother. The Balaputra's defeat to Jatiningrat was recorded in Shivagrha inscription that mentioned Balaputra has constructed a fortress made of heaped hundreds of stones for his refuge. With the retreat, Central Java fell to the hands of Sanjaya, ending Sailendra's rule over the area. The Sanjayas later founded the Medang Kingdom and continued to rule Java until Srivijaya reasserted its dominance over the island in the 11th century.
