Ashoka the Great: Kalinga, Buddhism and India’s Flag Wheel
Lion Capital of Ashoka 3.jpg

You may know the story in one line. A king wins a bloody war, feels horror, and turns to Buddhism. The real record is more interesting. And you can see its legacy every time you look at the Indian flag.

This article follows what Ashoka himself carved in stone. It also covers the monuments that survive and the wheel at the centre of India’s flag.

Who was Ashoka the Great?

Ashoka ruled the Maurya Empire from about 268 to 232 BCE. He was its third ruler. The Puranas and the Mahavamsa name his father as Bindusara. They name his grandfather as Chandragupta, who founded the Maurya dynasty.

His capital was Pataliputra. It stood where the city of Patna now stands, in the Indian state of Bihar.

His birth date is a gap. No text from his own time records it. You will often see “about 304 BCE”, but that is an estimate, not a fixed year.

What happened at Kalinga?

Kalinga lay roughly where the Indian state of Odisha is today. That is on India’s east coast. Ashoka conquered it.

Rock Edict XIII gives the timing. Kalinga fell eight years after Ashoka’s coronation. If his reign began around 268 BCE, that puts the war around 261 BCE.

The same edict gives the numbers behind the famous headline. It says 100,000 people were killed. It says 150,000 were deported. It says even more died from other causes.

Read those figures carefully. They are the king’s own declaration. They are not a count made by an outside observer.

The edict is also a confession. Ashoka expresses his remorse for the killing, the deaths and the deportations in Kalinga.

Did he turn Buddhist overnight?

The popular version says yes. The evidence says it is not that simple.

One scholar, Eggermont, places Ashoka’s turn to Buddhism before the Kalinga war. Others question that dating. They ask how it fits with a violent conquest. They also point out that the inscriptions show a gradual commitment, not a single conversion.

Minor Rock Edict I adds a clue. Ashoka says he had been a Buddhist lay follower for more than two and a half years. But he says his zeal grew only when he drew closer to the Sangha, the Buddhist community.

So a safer summary is this. Kalinga produced a public statement of remorse. His Buddhist devotion deepened over time.

Timeline

  • About 304 BCE: Estimated birth of Ashoka. The exact year is unknown.
  • About 268 BCE: Start of his Maurya reign.
  • About 261 BCE: Conquest of Kalinga. Rock Edict XIII places it eight years after his coronation.
  • About 250 BCE: Approximate date of the Sarnath Lion Capital.
  • 249 BCE: UNESCO’s date for the Ashoka pillar at Lumbini.
  • 232 BCE: Death of Ashoka and end of his reign.
  • 22 July 1947: Adoption of the Indian flag carrying the Ashoka Chakra.
  • 1950: The Sarnath Lion Capital is adopted as India’s state emblem.

What did the edicts say?

Ashoka’s messages on governance and morality are called the Dhamma Lipi. He had them cut into rocks and pillars. This was public writing meant to be read across his empire.

Several edicts deal with practical matters:

  • Rock Edict II says Ashoka provided medical care for people and animals. This applied in his own land and beyond his borders.
  • Rock Edict III orders officials to go on inspection tours every five years. They were to teach Dhamma and handle their other duties.
  • Rock Edict V says officials called Dhamma Mahamatras were appointed 13 years after his coronation.
  • Rock Edict XII urges people to listen to the teachings of other religions and to respect them.

Think of the first two as ancient versions of things you use today. A clinic and a vet’s office are both services a state can provide. A regular inspector’s visit is the same idea as a five-year review. Ashoka wrote both into stone.

Where can you find the edicts?

The inscriptions are spread across a huge area. They stand at Shahbazgarhi in Pakistan. They stand at Lauriya Nandangarh in Bihar. They stand at Girnar in Gujarat, at Dhauli in Odisha and at Yerragudi in Andhra Pradesh.

If you visit New Delhi, the National Museum holds a metal copy of the Girnar inscription. It represents the full set of 14 rock edicts.

The Kalinga region has a twist. There, two separate edicts replace Rock Edicts XIII and XIV, the ones that express remorse. The region he conquered has a different text from the rest of the empire.

Pillars and monuments from his reign

Two UNESCO World Heritage listings preserve work from his time.

  • Lumbini, Nepal: UNESCO dates the Ashoka pillar here to 249 BCE. The site is the birthplace of the Buddha.
  • Sanchi: In the 3rd century BCE, during Ashoka’s reign, a monolithic pillar and a brick stupa were built. The stupa was enlarged later.

The Ashoka Chakra: the wheel on India’s flag

The best-known link between Ashoka and the modern world is at Sarnath. The Lion Capital of Ashoka dates to about 250 BCE, according to a Berkeley art-history source. It has four lions standing back to back on a circular base.

The capital is carved from Chunar sandstone. Today it is displayed in the main hall of the Archaeological Museum at Sarnath.

The base of the capital carries a wheel. The navy blue, 24-spoked Ashoka Chakra in the white band of the Indian flag takes its design from that wheel. The Constituent Assembly adopted the flag on 22 July 1947.

The story continues in 1950. A graphic adaptation of the Sarnath Lion Capital became India’s official state emblem.

So when you see the flag at a sports match or a national holiday, you are looking at a motif from an ancient carved stone.

Details you won’t find in guidebooks

  • The royal kitchen. Rock Edict I says that two peacocks and a deer, though not every day, were being killed for the palace kitchen. It adds that even these would not be killed in the future.
  • A very long protected list. The list of protected creatures in Pillar Edict V includes bats and queen ants.
  • A name that proves the link. The Maski inscription uses the name Ashoka together with the title Devanampriya. This confirms that the inscriptions belong to the king.
  • Animals on the base. The base of the Sarnath capital shows a horse, a lion, a bull and an elephant in relief. Between each pair of animals sits a 24-spoked wheel.
