History of Ancient Odisha: from Kalinga to the Gangas

01 · Overview

What is ancient Odisha?

The history of ancient Odisha runs from the first human settlements in the region to the early twelfth century CE, when the Eastern Ganga ruler Anantavarman Chodagangadeva brought the coast under one imperial dynasty and the medieval age began.

Across these centuries Odisha was never a single fixed kingdom. Kalinga, Utkala, Odra, Tosali, Kongoda and Kosala rose, merged and separated. What connects them is a shared coastline, the river valleys of the Mahanadi, Brahmani and Baitarani, and a culture that absorbed Hindu, Buddhist, Jain and tribal traditions.

02 · Timeline

Timeline of ancient Odisha

Many early dates are approximate and some are still debated. This timeline follows the most widely accepted dating; gold markers show turning points.

1. Stone Age

   Stone tools from river valleys in Mayurbhanj, Sundargarh, Dhenkanal and other districts show hunter-gatherers in the region; painted rock shelters survive in western Odisha.

2. c. 2000 BCE onward

   Farming villages with pottery appear, as at Durgadevi in Balasore and Golabai Sasan near Khurda.

3. 1st millennium BCE

   Iron-using communities spread, as shown by early Iron Age tools at Jalalpur, Cuttack. Kalinga appears in the epics, Puranas and Buddhist texts.

4. 4th century BCE

   A Nanda king controls Kalinga for a time — recalled centuries later in the Hathigumpha inscription.

5. c. 261 BCE

   Ashoka conquers Kalinga in the Kalinga War; Tosali and Samapa become Mauryan administrative centres.

6. c. 1st century BCE

   Kharavela of the Mahameghavahana (Chedi) line restores Kalinga’s power and patronises Jainism at Udayagiri–Khandagiri.

7. c. 4th–5th century CE

   Samudragupta’s southern campaign passes through the region; the Matharas rule in Kalinga.

8. c. 6th–8th century CE

   The Sailodbhavas rule Kongoda and the first Bhubaneswar temples rise. Xuanzang visits Odra, Kongoda and Kalinga in the 7th century.

9. c. 8th–10th century CE

   The Bhaumakaras rule from near Jajpur; Ratnagiri and Lalitgiri flourish as Buddhist centres.

10. c. 10th–11th century CE

    The Somavamsis unite Kosala, Utkala and Kalinga; the Mukteswar and Lingaraj temples are built.

11. Early 12th century CE

    Anantavarman Chodagangadeva of the Eastern Gangas brings Utkala under Ganga rule — the start of medieval Odisha.

03 · Evidence

Sources of ancient Odisha’s history

Historians rebuild Odisha’s ancient past from four kinds of evidence: inscriptions on rock and copper plates, coins, literary texts (Indian and foreign) and archaeological remains. Inscriptions are the most reliable, because they were written at the time by or for the rulers themselves.

04 · Land & names

Historical geography and ancient names

Kalinga usually meant the coastal belt between the Mahanadi and the Godavari; Utkala and Odra referred to the northern and central coastal plains; Tosali was a Mauryan province, and Kongoda the land around Ganjam and Chilika. Western Odisha formed part of Dakshina Kosala. These boundaries shifted with every dynasty, so the same place can carry different names in different sources.

05 · Before kingdoms

Earliest settlements: Stone Age to Iron Age

Long before any kingdom, people lived along Odisha’s rivers and hills. Stone tools, painted rock shelters, early farming villages and iron implements show a continuous story of settlement — and recent excavations keep pushing that story further back.

06 · Four-part series

The Buddha and Kalinga

Buddhist tradition links Kalinga and Utkala with the Buddha’s own lifetime — from the merchants Tapassu and Bhallika, remembered as his first lay followers, to the tooth relic said to have been carried to Dantapura in Kalinga after his death.

07 · c. 261 BCE

The Kalinga War

Kalinga was one of the few regions outside the Mauryan Empire when Ashoka came to the throne. In about the eighth year of his reign he invaded. In his 13th Major Rock Edict Ashoka records that 150,000 people were deported, 100,000 were killed and many more died afterwards — and that the suffering filled him with remorse. The war marked his turn to Dhamma.

Sisupalgarh: an ancient fortified city

On the edge of Bhubaneswar lie the ramparts of Sisupalgarh, one of the best-preserved early historic cities in India — roughly square, each side a little over a kilometre long, with massive earthen walls and eight monumental gateways. It was first excavated by B. B. Lal in 1948 and studied again by Monica L. Smith and R. K. Mohanty in the 2000s. Many scholars identify it with Tosali or with Kharavela’s capital, Kalinganagari, though this is not settled.

08 · Mahameghavahana dynasty

Kharavela, emperor of Kalinga

Kalinga regained its independence after the Mauryas, and under Kharavela of the Mahameghavahana (Chedi) family it became one of the strongest kingdoms in India. The Hathigumpha inscription on Udayagiri hill describes his reign year by year: repairing his capital after a cyclone, campaigns against the Satavahanas, Magadha and a southern confederacy, remitting taxes, and building caves for Jain monks. His date is debated, but most historians place him in the 1st century BCE.

09 · Ruling houses

Dynasties of ancient Odisha

From the 4th century CE, copper-plate land grants make Odisha’s history clearer again. Smaller ruling families — the Nalas of Koraput, the Pitrbhaktas, the Vigrahas, the Bhanjas, Sulkis and Tungas — ruled alongside the major dynasties below.

• The Matharas

  c. 4th–5th century CE · Southern Kalinga

  Known mainly from copper-plate grants that also tell us about land, villages and Brahmin settlement in the period after Samudragupta’s campaign.

• The Sailodbhavas

  c. 6th–8th century CE · Kongoda

  Rulers of the land around Chilika and the Rushikulya; their reign saw the start of the Kalinga temple style in the Parsurameswara temple.

  c. 8th–10th century CE · Coastal Odisha

• The Somavamsis

  c. 10th–11th century CE · Kosala → Utkala

  Rising in western Odisha, they were the first to rule Kosala, Utkala and Kalinga together; the Mukteswar and Lingaraj temples belong to their age.

• The Eastern Gangas

  c. 5th century CE onward · Kalinganagara

  In the early 12th century Anantavarman Chodagangadeva conquered Utkala and began the Jagannath Temple at Puri, opening the imperial, medieval chapter.

10 · The sea

Maritime trade and Kalinga’s seafarers

Kalinga’s long coast made it a natural base for sea trade. Ports such as Palur, Manikpatna and Khalkatapatna connected it with Sri Lanka, Myanmar and the islands of Southeast Asia, and finds of foreign pottery and coins confirm these links. The festivals of Bali Jatra and Boita Bandana still remember the voyages of the old sadhabas (merchants).
