The maritime history of Odisha (ଓଡ଼ିଶାର ସାମୁଦ୍ରିକ ଇତିହାସ) is the story of ancient Kalinga's trade and cultural contacts across the Bay of Bengal, with Sri Lanka, Myanmar and Southeast Asia. Britannica describes Kalinga as a maritime power from about the 1st century CE. Archaeology at coastal sites confirms long-distance trade, while much of the popular picture, such as merchant Sadhabas sailing to Bali on Kartika Purnima, comes from tradition and festivals rather than written records.

What does archaeology show?
Manikapatna
Manikapatna, near the northern end of Chilika Lake by the Bhargavi river, is one of the richest port sites in Odisha. Finds reported there include fine grey rouletted ware, knobbed ware and amphora fragments associated with the early historical Indian Ocean trade; Chinese celadon and porcelain of later centuries; pottery from Myanmar, Thailand and the Arab world; and a Sri Lankan coin of King Sahassa Malla (late 12th century). Manikapatna is sometimes identified with Che-li-ta-lo, the port described by the Chinese pilgrim Xuanzang (Hiuen Tsang) in the 7th century, but that identification is not certain. The site appears to have been active from early historical times into the 19th century.
Palur and the southern coast
Palur, near the Rushikulya river in Ganjam district, was an important port by the 2nd century CE. Roman-period pottery and amphora fragments have been reported there, evidence that it was linked to the wider Indian Ocean trade.
Other sites
Sites such as the port of Khalkattapatna and Sisupalgarh near Bhubaneswar, an early historical fortified city often identified with Ashoka's provincial capital Tosali, help fill in the picture of an urban, trading society on the coast and its hinterland. Tamralipta (Tamluk, now in West Bengal), the great port of the Ganga delta, served Kalinga's northern trade and is named by Chinese travellers as a departure point for Sri Lanka and China.
Ships in stone
The earliest known depiction of ships in Odisha is a sculptured frieze showing two vessels, found near the Brahmeswara Temple in Bhubaneswar and now in the Odisha State Museum. A boat carved at the 13th-century Konark Sun Temple carries a giraffe, which has been read as a sign of indirect contact with Africa, probably through Arab shipping.
What do written sources say?
- Classical geographers. Ptolemy's Geography (2nd century CE) names places on this coast, such as Nanigaina, Katikardama and Kannagara, which some scholars identify with Puri, Cuttack and Konark. These identifications are proposals, not certainties.
- Chinese pilgrims. Faxian (early 5th century) sailed home from Tamralipta, and Xuanzang (7th century) described sea routes from the eastern ports to Sri Lanka and beyond.
- Sri Lankan records. The 12th-century king Nissanka Malla of Sri Lanka claimed descent from a royal family of Kalinga, part of a wider pattern of Kalinga links in Sri Lankan chronicles.
- Southeast Asian usage. The word Keling, from Kalinga, was used in the Malay world for people from India. The Portuguese chronicler Castanheda in the 16th century wrote of Keling merchants in Malacca as people of Kalinga.
Southeast Asia: influence and debate
Britannica notes that Kalinga's overseas activity may have been connected with the rise of the Shailendra dynasty of Java in the 8th century. Historians such as R. C. Majumdar argued for Kalinga origins for some Southeast Asian ruling families, but many modern scholars see cultural exchange in the Bay of Bengal as involving several Indian regions at once, not Kalinga alone. Statements that Odia sailors "founded" kingdoms in Java, Bali or Cambodia should be read as theories, not established facts.
What does tradition remember?
Odia culture keeps a vivid memory of the sea:
- Sadhabas and boitas. Folk tradition remembers the Sadhabas, merchant seafarers who sailed in large boats called boitas, carrying goods such as textiles and returning with wealth from distant islands.
- Bali Jatra. Held at Cuttack on the Mahanadi from Kartika Purnima, the Bali Jatra fair commemorates the voyages of the Sadhabas to Bali, Java, Sumatra and Sri Lanka. Tradition holds that Kartika Purnima was chosen because the winds then favoured sailing.
- Boita Bandana. Before dawn on Kartika Purnima, people across Odisha float small boats of paper, banana bark or cork with lamps, singing "Aa ka ma boi". See Boita Bandana.
- Taapoi and Khudurukuni Osha. The folk tale of Taapoi and household rituals such as Khudurukuni Osha are linked in Odia tradition to the families of seafarers.
These customs are valuable as living memory of a maritime past. They are not, on their own, historical evidence for particular voyages or dates.
Why did Odisha's maritime trade decline?
Two causes are commonly cited. First, harbours silted up: Chilika Lake, once a sheltered anchorage, gradually became less accessible to seagoing ships. Second, Arab sailors entered Bay of Bengal trade from as early as the 8th century, and later Portuguese, Dutch, English and French shipping came to dominate, leaving Odisha's sailors largely to coastal trade. Modern ports such as Paradip and Gopalpur have given Odisha a new maritime role.
