An inscription in the Tamil language, the
Lobu Tua Inscription dated 1088 AD, has been found on the western coast of Sumatra island at Lobu Tua,
North Sumatra province, Indonesia. It was erected by a Tamil merchant
guild, the
Ayyavole 500 (“the 500 of the thousand directions”) which enjoyed the patronage of the
Chola rulers. The inscription mentions the guild as “having met at the
velapuram in Varocu”. “Varocu” is Barus, an ancient port located not far from Lobu Tua, which had played a major role in the
camphor and
benzoin trade since the 9th century. These valuable products were in high demand in China, India and the Middle East and came from the forests in the northern Sumatra hinterland. From there, they were brought to Barus and exported. Tamil were among the foreign merchants who would come to Barus and buy the camphor and benzoin from local traders. In 1017 and 1025, the Chola kings had sent fleets to raid ports controlled by Sriwijaya in the
Malacca Straits. After these successful attacks, the Chola seem to have been in a position to intervene in the region for the rest of the 11th century. This allowed for an increased presence of Tamil merchant guilds in Sumatra. ==Tanjore Inscription==
