Chandru Ramesh — Was Mahabharata Real? The Evidence Behind India’s Greatest Epic

Was the Mahabharata really history? Or is it simply mythology passed down through generations?

In this episode of Supertalks, Raghav sits down with Chandru Ramesh, former software engineer turned historian, author and space archaeology researcher, and Director of Historika Foundations, to investigate one of the biggest questions surrounding Indian civilisation: Was the Mahabharata actually a historical event?

Chandru is the author of Mahabharata: Myth or History?, a research-driven work featuring 300+ pieces of evidence and 1,000+ citations drawn from archaeology, epigraphy, numismatics, petroglyphs, sculpture, Vedic literature, Buddhist texts and Tamil Sangam literature. Using LiDAR, satellite imagery, GIS, drone mapping and geospatial technologies, he investigates the physical and geographical evidence connected to India’s ancient past.

What we cover: Why Chandru argues that the Mahabharata should be studied as history rather than mythology. The 300+ pieces of physical evidence that he believes support the historicity of the Mahabharata. How archaeology, inscriptions, coins, sculptures, petroglyphs and ancient literature can help reconstruct India’s past. The scientific and archaeological evidence from Vedic literature that helps date the Mahabharata period. Why Chandru challenges Nilesh Oak’s astronomical dating of the Mahabharata and why astronomy alone may not be enough to establish a historical date. The world map during the Mahabharata period and the great kingdoms that existed at the time. The historical evidence surrounding the Pandavas and Kauravas. Arjuna, Bhima, Yudhishthira and the greatest warriors of the Mahabharata. What happened to the Pandavas after the war. The Mahaprasthanika, the final journey of the Pandavas and what the ancient texts actually describe. Krishna’s date of departure from this world and the evidence used to establish it. How LiDAR, satellite imagery, GIS and drone mapping are helping researchers investigate ancient sites. What space archaeology can reveal about India’s civilisational history. The difference between mythology, tradition and history and how ancient events can be investigated using modern scientific methods.

From archaeology and ancient texts to satellite imagery, inscriptions, astronomy and geospatial research, this conversation examines the Mahabharata through evidence rather than belief.

This is not just a conversation about whether the Mahabharata is mythology or history. It is an investigation into how much of India’s ancient past can actually be reconstructed through evidence — and what that evidence tells us about one of the greatest civilisations in history.
