Until the Keeladi site was discovered, archaeologists by and large believed that the Gangetic plains in the north urbanised significantly earlier than Tamil Nadu. Historians have often claimed that large scale town life in India first developed in the Greater Magadha region of the Gangetic basin. This was during the ‘second urbanisation’ phase. The ‘first urbanisation phase’ refers to the rise of the Harappan or Indus Valley Civilisation. Tamil Nadu was thought to have urbanised at this scale only by the third century BCE. The findings at Keeladi push that date back significantly. … Based on linguistics and continuity in cultural legacies, connections between the Indus Valley Civilisation, or IVC, and old Tamil traditions have long been suggested, but concrete archaeological evidence remained absent. Evidence indicated similarities between graffiti found in Keeladi and symbols associated with the IVC. It bolstered the arguments of dissidents from the dominant North Indian imagination, who have argued for years that their ancestors existed contemporaneously with the IVC. … All the archaeologists I spoke to said it was too soon to make definitive links between the Keeladi site and the IVC. There is no doubt, however, that the discovery at Keeladi has changed the paradigm. In recent years, the results of any new research on early India have invited keen political interest, because proponents of Hindu nationalism support the notion of Vedic culture as fundamental to the origins of Indian civilisation. … The Keeladi excavations further challenge the idea of a single fountainhead of Indian life. They indicate the possibility that the earliest identity that can recognisably be considered ‘Indian’ might not have originated in North India. That wasn’t all. In subsequent seasons of the Keeladi dig, archaeologists discovered that Tamili, a variant of the Brahmi script used for writing inscriptions in the early iterations of the Tamil language, could be dated back to the sixth century BCE, likely a hundred years before previously thought. So not only had urban life thrived in the Tamil lands, but people who lived there had developed their own script. “The evolution of writing is attributed to Ashoka’s edicts, but 2600 years ago writing was prevalent in Keeladi,” Mathan Karuppiah, a proud Madurai local, told me. “A farmer could write his own name on a pot he owned. The fight going on here is ‘You are not the one to teach me to write, I have learnt it myself.’”
