Chola Maritime Power and Southeast Asian Trade

Under Rajendra Chola I, the Chola state maintained what was likely the most capable navy in the Indian Ocean of its time, using it to protect and expand lucrative trade routes connecting South India to Southeast Asia and China. In 1025 CE, the Cholas launched a maritime campaign against the Srivijaya kingdom (centered in modern Sumatra and the Malay Peninsula), capturing key ports to secure trade routes through the Strait of Malacca. Tamil merchant guilds such as the Ayyavole 500 operated across this maritime network, and Tamil inscriptions have been found as far as Sumatra and southern China, attesting to the reach of Chola-era commerce. This period left a lasting cultural imprint across Southeast Asia, visible in temple architecture, script influences, and Hindu-Buddhist religious practice in the region.
