Rajendra Chola I

Overseas conquests
Before the fourteenth year of Rajendra’s reign c. 1025, the Chola Navy crossed the ocean and attacked the Srivijaya kingdom of Sangrama Vijayatungavarman. Kadaram, the capital of the powerful maritime kingdom, was sacked and the king taken captive. Along with Kadaram, Pannai in present day Sumatra and Malaiyur in the Malayan peninsula were attacked. Kedah (now in modern Malaysia) too was occupied.

Sangarama Vijayatungavarman was the son of Mara Vijayatungavarman of the Sailendra dynasty. Srivijaya kingdom was located near Palembang in Sumatra.

There are no records to explain the nature of and the reason for this naval expedition. The Sailendra dynasty had been in good relations with the Chola Empire during the period of Rajaraja Chola I. Rajaraja encouraged Mara Vijayatungavarman to build the Chudamani Vihara at Nagapattinam. Rajendra confirmed this grant in the Anaimangalam grants showing that the relationship with Srivijaya was still continued be friendly. The exact cause of the quarrel that caused the naval war between Cholas and Srivijaya remains unknown.

The Cholas had an active trade relationship with the eastern island. Moreover the Srivijaya kingdom and the South Indian empires were the intermediaries in the trade between China and the countries of the Western world. Both the Srivijaya and Cholas had active dialog with the Chinese and sent diplomatic missions to China.

The Chinese records of the Song Dynasty show that first mission to China from Chu-lien (Chola) reached that country in 1015 C.E. and the king of their country was Lo-ts’a-lo-ts’a (Rajaraja). Another embassy from Shi-lo-cha Yin-to-loChu-lo (Sri Raja Indra Chola) reached China in 1033 C.E. and a third in 1077 C.E. during Kulothunga Chola I. The commercial intercourse between Cholas and the Chinese were continuous and extensive.

One reason could be a trade dispute stemming from some attempts by Srivijaya to throw some obstacle between the flourishing trade between China and the Cholas. Whatever the actual cause of this expedition, it is difficult to believe that, even if we take all the achievements narrated in Rajendra’s inscriptions are accepted as literally true, the campaign led to any permanent territories rather than a vague acceptance of the Chola suzerainty by Srivijaya. Sangaram Vijayatungavarman was restored to the throne at his agreement to pay periodic tribute to Rajendra.

Tanjavur inscriptions also state that the king of Kambhoja (Kampuchea) requesting Rajendra’s help in defeating enemies of his Angkor kingdom.
