Rajendra Chola was a chola king who reigned the southern India between 1014-42 and during his time extended his empire to Sri Lanka, Mayanmar, Malaya, Indonesian islands . During his reign the kingdom was called the "Golden Age of Cholas." The greatest of Indian monarchs who dreamt of ruling over overseas territories were undoubtedly the splendid Chola father-and-son, Rajaraja and Rajendra. Thanks to their imperial energy and unprecedented vision, the Cholas dominated the amorphous maritime empire of the Sailendras for nearly a century. As Balram Srivastava observes in Rajendra Chola: 'The Chola navigators supported the Indian colonies in the far east and established a firm rule of the Cholas in Sri Vijaya. Their success nearer home, in Sri Lanka, was also splendid. They crossed the sea between India and Sri Lanka so often that it became a lake to them. Rajaraja's adventures may be dismissed as having happened within the extended coastal waters of India. But his son Rajendra was a true conqueror of overseas territories. Says Dr. K.V. Hariharan in The Chola Maritime Activities in Early Historical Setting: 'Of the most notable was Rajendra Chola's naval expedition against Kadaram. In this expedition, he defeated a king named Sangama Vijayottungavarman, the king of Kataha, belonging to the Sailendras of Java. The territories wrested by the Cholas from this king consisted of the extensive kingdom of Sri Vijaya, which at one time included Sumatra and Java, with its capital at Palembang. Not only did Rajendra's army sack Kadaram and the Sri Vijaya capital, but it also took the Sri Vijaya king Sangrama Vijayottungavarman captive. The kingdom was restored to him only after he acknowledged Chola suzerainty. Tamil inscriptions recovered from the region show that there was Chola military presence till at least 1088 in the Malay archipelago. There is evidence to show that the king of Kambujadesa (modern Cambodia) sent a chariot to the Chola, probably to appease him so that his strategic attention does [sic] not extend further than the Malay peninsula. After his death the Chola kingdom began to decline. One can say that the first major shipping activity or trade activity through the sea with china was during the reign of King Rajendra chola.
