Mediaeval Tamil involvement in Northern Sumatra, C11–C14 (The gold and resin trade
E. Edwards McKinnon’s 1996 article in the Journal of the Malaysian Branch of the Royal Asiatic Society argues that Tamil merchant guilds, particularly the Ayyavole, established a sustained trading presence in northern Sumatra from the late eleventh to the mid-fourteenth century, exploiting the region’s camphor, benzoin, and gold resources through a transinsular network linking the west coast port of Barus to the east coast settlement of Kota Cina. Drawing on inscriptional, archaeological, and ethnolinguistic evidence, McKinnon reconstructs the commercial infrastructure that allowed these guilds to funnel high-value forest products from the Bukit Barisan hinterland to maritime routes connecting southern China, Sri Lanka, and the Red Sea.
Summary
The article situates Tamil mercantile expansion in northern Sumatra within the broader context of Cola imperial ambition and the collapse of Srivijayan maritime hegemony following Rajendra Cola’s raid of 1025 CE. McKinnon argues that the raid, recorded in the Tanjore inscription of 1030/31, was motivated predominantly by economic opportunity rather than mere plunder, and that Tamil merchants who had already been trading in Southeast Asian waters provided the intelligence that made such operations possible. The destruction of Srivijayan control over the Straits of Melaka opened the way for direct Tamil intervention in Sumatran commerce, a process that had already been prefigured by similar interventions in Sri Lanka (pp. 85–89).
The core of the argument rests on the identification of two complementary trading nodes: Lobu Tuo (Barus) on the west coast, where the Ayyavole merchants erected a dated stele in 1088 CE, and Kota Cina near Belawan on the east coast, where McKinnon’s own excavations revealed a substantial Tamil community with imported religious imagery, gold-working debris, and massive quantities of Song and Yuan period Chinese ceramics. The strategic logic of the network was transinsular: by establishing an east coast base at Kota Cina, Tamil merchants could exploit ancient overland trails across the Karo plateau to access camphor and benzoin sources in the western Bukit Barisan, thereby saving months of dangerous sea travel around the western tip of Sumatra (pp. 89–97).
McKinnon supplements the archaeological and epigraphical record with ethnolinguistic evidence from the Karo Batak people of the hinterland, pointing to clan names of apparent Dravidian origin (Berahmana, Colia, Keling, Maha, Pandia), the structural parallel between the Karo urung village federations and medieval Tamil urom assemblies, and approximately 155 Sanskrit-derived words in the Karo vocabulary that appear to have entered via Tamil. A Karo folk tale recounting the arrival of a wealthy Indian merchant backed by armed retainers further supports the thesis of a mercantile-military presence in the interior (pp. 91–94).
Key Findings
- The Lobu Tuo (Barus) stele, dated to Saka year 101 (A.D. 1088), was erected by the ainnurruvar Ayyavole merchants, who styled themselves “the Five Hundred of a Thousand Directions” and regulated a fee of anju-tundayam in gold payable by ship’s captains before they could “step on the cloth spread” (p. 89).
- Kota Cina yielded three brick-built sacral structures (a Siva temple with a polished lingam, a Visnu temple, and a Buddhist asrama), two seated Buddha images in provincial Tamil style, a gold tali imitating a Sassanid Egyptian dinar, 13th-century Sri Lankan coins of Sahasa Malla and Lilavati, and carinated red-slipped earthenware closely related to southern Indian wares (pp. 95–96).
- The best quality camphor (Dryobalanops aromatica) came exclusively from the isolated Lai Cinendang valley, a tributary of the Singkel river above Barus in the Pakpak country, while benzoin (Styrax benzoin) was collected from a much more extensive area and exported in quantity from approximately the 7th century CE (p. 89).
- The Sinyombak sub-clan of the Karo Sembiring bears sept names—Berahmana, Colia, Depari, Keling, Maha, Meliala, Muham, Pandia, Pelawi, and Tekang—that McKinnon identifies as having “only [arisen] from close association with people of Dravidian stock” (p. 92).
- The pekualuh ceremony, in which ancestral bones were set adrift on ornate boats, was last celebrated in the early 20th century at Siberaya, a village of some 3,000 inhabitants occupying a strategic position in the network of ancient trails linking the resin-producing western highlands to the east coast (p. 93).
- Chinese ceramic evidence at Lobu Tuo suggests the site was abandoned around the same time Kota Cina was established, i.e. about the end of the 11th century, indicating a deliberate “switch” of the camphor export focus from the west to the east coast (p. 89).
Conclusion
McKinnon concludes that the Tamil merchants, operating through their guild structures with their characteristic combination of commercial acumen and armed mercenary support, organised a systematic exploitation of Sumatran forest resins and gold that was sustained only as long as the guilds themselves remained present. Once they withdrew, the supporting infrastructure collapsed, but the cultural memory persisted in place names, clan designations, and ritual practices such as the pekualuh, which survived until discouraged by Dutch missionaries in the early 20th century. The Indian associations were ultimately obscured by the more recent and violent impact of 17th-century Acehnese incursions into northeast Sumatra (p. 97).
Context
- The article draws substantially on McKinnon’s own fieldwork at Kota Cina (documented in his 1984 JMBRAS article and 1984 Cornell PhD thesis) and his 1994 study of Tamil imagery in northeast Sumatra, positioning the piece as a synthesis of primary archaeological data with the broader inscriptional and historiographical literature on Tamil guilds.
- The study contributes to the historiography of Srivijayan decline by offering a specific commercial mechanism—Tamil guild intervention in the resin and gold trade—as a factor in the redistribution of maritime power in the region after 1025, complementing Wolters’ political analyses.
