Baliyatra

The Kalinga Empire, located in present-day Odisha, possessed a remarkable maritime heritage. Beginning in the 4th and 5th centuries BC, ports such as Tamralipti, Manikpatna, Chelitalo, Palur, and Pithunda facilitated India's connections across the sea. The Kalingas established commercial networks with Sri Lanka, Java, Borneo, Sumatra, Bali, and Burma — collectively known as the Suvarnadvipa, now Indonesia.

Kalingas constructed impressive vessels called "Boitas" with copper hulls capable of transporting seven hundred passengers and cargo. The Bay of Bengal earned the designation "Kalinga Sea" due to the prevalence of these ships. The classical poet Kalidasa referenced the Kalinga king as "The Lord of the Sea" in his Raghuvamsa.

By the second century BC, Indian mariners had developed sophisticated knowledge of monsoon patterns and ocean currents, enabling southern routes across the Indian Ocean. Lake Chilika served as a crucial harbour for these expeditions, with ancient pottery fragments still visible along its shores.

Maritime voyages followed strategic timing: ships departed Odisha in mid-November using north-eastern monsoon winds to sail toward Sri Lanka. After replenishing supplies, they crossed the Indian Ocean to Sumatra's northern coast before proceeding toward Java and Bali. The return journey exploited counter-currents and the May south-west monsoon, allowing merchants approximately two months for trading activities.

While Tamil, Andhra, Bengal, and north-western merchants also participated in this trade, the Sadhaba merchants of Kalinga maintained dominant influence. Consequently, Indians became known as "keling" by Malays and Javanese populations.

This maritime legacy persists in Odisha's cultural practices. The Kartik Purnima festival, occurring in mid-November or December, commemorates the sailing season through rituals involving paper boats with oil lamps. The annual Bali Yatra fair in Cuttack celebrates "The Journey to Bali," accompanied by traditional songs and performances.

Commercial activity fostered cultural exchange. Within centuries, Indic civilisation profoundly influenced Southeast Asia through Buddhism and Hinduism, the Mahabharata and Ramayana epics, Sanskrit language, scripts, and temple architecture. Despite subsequent Islamic influence, colonialism, and modernity, ancient Indian cultural imprints remain visible in names, vocabulary, and artistic traditions.
