Chola dynasty
The relation between Srivijaya and the Chola dynasty of southern India was initially friendly during the reign of Raja Raja Chola I. In 1006 CE a Srivijayan Maharaja from Sailendra dynasty, king Maravijayattungavarman, constructed the Chudamani Vihara in the port town of Nagapattinam. However, during the reign of Rajendra Chola I the relations deteriorate as the Chola Dynasty started to attack Srivijayan cities.
