Ancient India's Maritime Empire:
2,000 Years of Indian Ocean Dominance
At Lothal in Gujarat — part of the Indus Valley Civilisation — archaeologists excavated a structure dating to approximately 2400 BCE that has been identified as a dry dock: a rectangular basin connected to the sea by a channel, designed for loading and unloading ships. If the identification is correct, it is the oldest known purpose-built dock in the world, predating anything comparable in Egypt or Mesopotamia by centuries.
India's maritime history did not begin or end at Lothal. For over two thousand years — from the Maurya period through the Chola Empire and beyond — Indian merchants, sailors, and shipbuilders were the dominant force in Indian Ocean commerce, connecting the Persian Gulf, the Red Sea, East Africa, and Southeast Asia in a trading network of extraordinary reach and sophistication.
This history is documented not just in Indian texts but in Roman, Greek, Arab, and Chinese sources — multiple independent traditions that all confirm the centrality of Indian ships and merchants in the ancient maritime world.
The Arthaśāstra on Shipbuilding
Kauṭilya's Arthaśāstra (c. 4th century BCE) contains an entire chapter on naval administration (nāvādhyakṣa — superintendent of ships). It describes:
• Different classes of ships: river ships, coastal ships, and ocean-going ships
• Regulations for ship construction and maintenance
• Duties of the nāvādhyakṣa including port regulation, tariffs, and merchant licensing
• Rules for maritime trade — penalties for smuggling, regulations for foreign merchants

The Chola Maritime Empire (9th–13th century CE)
The Chola dynasty of Tamil Nadu was the most powerful maritime empire in ancient South Asia. At its peak under Rājendra Chola I (1014–1044 CE), the Chola navy conducted a large-scale naval expedition across the Bay of Bengal, reaching as far as the Malay Peninsula and Sumatra — the largest ancient Indian naval operation ever documented.
Chola trade networks connected India to China, Arabia, and East Africa. The archaeological evidence is extensive: Chola coins have been found from Yemen to China, and Chinese annals document Chola embassies to the Song court.
The Chola also disseminated Indian culture — Hinduism, Buddhism, Sanskrit literature, and temple architecture — across Southeast Asia. Bali retains a living Hindu tradition today that traces directly to this Chola-era diffusion.
