Chola Invasion of Srivijaya (1025): Rajendra's Naval Raid

The Chola invasion of Srivijaya was a naval expedition sent by the South Indian emperor Rajendra Chola I across the Bay of Bengal in about 1025. Chola forces raided a string of ports belonging to Srivijaya, the maritime power of Sumatra and the Malay Peninsula, and captured its king. It is the best-documented overseas military campaign by any medieval Indian state and shows the reach of Chola sea power.

Background

Srivijaya, centred on Palembang in southern Sumatra, had grown since the late seventh century into a trading empire controlling the Strait of Malacca and the Sunda Strait, the main sea routes between the Indian Ocean and the South China Sea. Its rise is described in the article on the rise of Srivijaya. Ships carrying cotton, spices, aromatics, porcelain and silk had to pass through waters it controlled.

The Cholas of South India were at the height of their power. Rajaraja I (r. 985–1014), builder of the Brihadisvara Temple at Thanjavur, had built an empire across southern India and northern Sri Lanka, and his son Rajendra I (r. 1014–1044) had sent an army on the Ganges expedition. Tamil merchant guilds, such as the association known as the Five Hundred (Ainnurruvar), traded widely across the Indian Ocean.

Relations had at first been friendly. Around 1006 the Srivijayan king Mara Vijayottungavarman founded a Buddhist monastery, the Chudamani Vihara, at the Chola port of Nagapattinam, and Rajaraja granted a village for its upkeep. The grant was later confirmed in copper plates known as the Larger Leiden Plates, now in Leiden in the Netherlands.

Causes

No source states why Rajendra attacked. Historians have proposed several explanations:

• Trade: Srivijaya may have imposed heavy duties or obstructed Tamil merchants trading with China. The Cholas sent embassies to the Song court in 1015 and 1033, showing their interest in the China trade.
• Prestige: The raid fits Rajendra’s pattern of spectacular campaigns, like the march to the Ganges, intended to display imperial power.
• Regional politics: Some scholars link the expedition to disputes in mainland Southeast Asia, including Chola contacts with the Khmer empire.

Most historians see the commercial motive as central, while recognising that the evidence is indirect.

The expedition

The main source is Rajendra’s meykirtti, a formal praise text carved in Tamil on temple walls, including at Thanjavur. It states that Rajendra sent many ships across the “rolling sea” and lists the places taken. These included Srivijaya itself; Kadaram, usually identified with Kedah on the Malay Peninsula; Malaiyur in Sumatra; Pannai on Sumatra’s east coast; Ilangasogam (Langkasuka) and Madamalingam (Tambralinga) on the Malay Peninsula; Ilamuridesam (Lamuri) in northern Sumatra; and Manakkavaram, the Nicobar Islands.

The inscription claims the capture of the Srivijayan king, Sangrama Vijayottungavarman, together with his elephants, treasure and a jewelled gateway called the Vidyadhara-torana. No numbers of ships or soldiers are recorded, and no Srivijayan or Chinese account describes the raid in detail.

The date of about 1025 comes from the regnal years of the inscriptions that first mention the expedition. The list of ports appears to follow a route along the Malacca Strait, suggesting a fleet that sailed from the Coromandel coast, struck Sumatra and the peninsula, and returned.

How the raid was possible

A voyage across the Bay of Bengal depended on the monsoon winds. Ships sailing east from the Coromandel coast generally used the south-west monsoon of the middle of the year and returned with the north-east monsoon late in the year, and sailors knew the routes well from centuries of trade. The Nicobar Islands, listed among the places taken, lay on the usual crossing to the Malay Peninsula and northern Sumatra.

The Chola state had access to many ships and experienced crews through the ports of its coast, such as Nagapattinam. Its earlier campaigns against Sri Lanka and the Maldives had also required moving troops by sea. Historians think the expedition probably combined royal forces with ships provided or hired from merchants, though the sources give no details.

Srivijaya, for its part, was a network of ports rather than a single territorial state. Its power depended on the loyalty of local rulers along the coasts and on its control of shipping. A rapid raid that struck one port after another could therefore do serious damage without the need to conquer large areas of land.

Key people

• Rajendra Chola I (r. 1014–1044): Chola emperor who ordered the expedition.
• Sangrama Vijayottungavarman: king of Srivijaya, captured according to Chola inscriptions.
• Mara Vijayottungavarman: earlier Srivijayan king who founded the monastery at Nagapattinam.

Consequences

The Cholas did not occupy Srivijaya permanently. The raid did, however, damage Srivijaya’s ports and prestige. Many historians see it as one cause of Srivijaya’s gradual decline, as power in Sumatra later shifted towards Jambi (Malayu) and other centres.

Chola involvement in the region continued. Around 1068, under Virarajendra, a Chola force intervened in Kadaram on behalf of a local ruler. Relations with Srivijaya were restored: in 1090 the Chola king Kulottunga I renewed the grants to the monastery at Nagapattinam, recorded in the Smaller Leiden Plates.

Chinese records continued to treat Srivijaya, which they called Sanfoqi, as a major trading state, and its envoys kept visiting the Song court during the eleventh century. In the twelfth and thirteenth centuries, however, Chinese writers described a changed landscape in which several ports competed for trade. By the late thirteenth century Javanese kingdoms such as Singhasari, and later Majapahit, had become the leading powers of the region.

Tamil merchants remained active in Southeast Asia. A Tamil inscription of 1088 from Lobu Tua near Barus in Sumatra records a guild of merchants there.

Legacy

The expedition is remembered in India as a symbol of Chola naval strength, and modern writers sometimes describe the Cholas as a “naval power”. Historians caution that the Chola fleet was probably built largely of merchant ships rather than a permanent navy, and that the raid was a single dramatic event rather than the start of an overseas empire.

The campaign also illustrates how closely South India and Southeast Asia were connected by trade and religion in this period, a connection seen in temples such as those of the Bujang Valley in Kedah and in the wider spread of Indian scripts and art.

Archaeological work in the Bujang Valley and at sites in Sumatra has uncovered Chinese ceramics, Middle Eastern glass and South Indian objects from this period, confirming how busy these ports were. Such finds cannot by themselves date the Chola raid, but they help explain why control of these harbours was worth fighting for.

Why it matters

The raid on Srivijaya shows that a medieval Indian state could project military force more than 2,000 kilometres across the sea. It reveals the importance of the Indian Ocean trade routes to the great powers of Asia, and it remains one of the clearest examples of conflict and contact between South and Southeast Asia before the arrival of Europeans.
