and soon performed the paramayoga by drowning himself in the
Tungabhadra. Virarajendra also successfully foiled the attempts of Sinhalese
king Vijayabahu I to overthrow the Chola power on the island. He then sent
another naval expedition for the conquest of Kadaram (Sri Vijaya) on behalf
of a prince who had come in search of his aid and protection (1068).
Kulottunga I Originally known as Rajendra II, this son of Rajaraja

epoch in the history of Chola architecture and art as he himself is the last of
the great Chola monarchs. Cholas, however, continued to be there even
afterwards as local chieftains.
The most striking feature of the administrative system of the Cholas was their
