The knowledge of the Tamils prior to the Indus Valley Civilization

26 Avani 2026 Introduction Keeladi, a small village located on the banks of the Vaigai River in Tamil Nadu’s Sivagangai district, has, for more than a decade, become one of the most debated sites in the Indian archaeological world. This excavation, begun in 2014, has brought to light thousands of artifacts that demonstrate the development of an urban civilization in Sangam-era Tamilakam. This article explains, on the basis of available information, the major discoveries of the Keeladi excavation and the debates among scholars regarding them. Beginning of the Excavation Under the leadership of Archaeological Survey of India (ASI) archaeologist Amarnath Ramakrishna, the first excavation at Keeladi was carried out in 2014–15. Initially, it began as a routine survey; however, the remains that surfaced at the site soon revealed its significance. Subsequently, this work was continued by the Tamil Nadu State Department of Archaeology and has so far been conducted in multiple phases. Artifacts Discovered To date, more than two hundred thousand artifacts have been recovered from the Keeladi excavation. Among them, the most notable are: • Brick structures: Brick walls laid out in a planned manner, drainage systems, and wells are regarded as early evidence of urban planning. • Tamil-Brahmi inscriptions: Tamil-Brahmi script inscribed on potsherds is key evidence that literacy was widespread among the people of that period. • Glass beads and ornaments: Fine glass beads, gold jewelry, and conch bangles exemplify the craftsmanship and aesthetic sensibilities of the time. • Evidence of the textile industry: Spinning whorls and needles indicate that textile weaving was carried out extensively in the town. • Evidence of foreign trade links: Roman coins and potsherds show that the people of Keeladi were also engaged in international trade. Carbon Dating and Its Significance Some of the remains found at Keeladi were subjected to Carbon-14 dating at the Beta Analytic laboratory in the United States. The results indicated that human habitation at Keeladi could be as old as around the 6th century BCE. If this date is correct, Tamil Nadu’s archaeology enthusiasts believe it would provide archaeological corroboration for the urban way of life described in Sangam literature. Debate Among Scholars There are differences of opinion in Indian archaeological circles regarding the Keeladi discoveries. The Tamil Nadu government and many archaeology enthusiasts view the Keeladi findings as evidence of “a distinct Tamil urban civilization comparable to, or earlier than, the Indus Valley Civilization.” This has also led to the proposal of a new conceptual framework termed the “Vaigai riverbank civilization.” In contrast, some archaeological experts caution that these conclusions should undergo broader, internationally rigorous re-examination. At one point, the transfer of the archaeologist who prepared the first report and delays in releasing the report also gave rise to political debates. Nevertheless, through the continued studies of the Tamil Nadu State Department of Archaeology, the Keeladi discoveries are being documented on an ongoing basis. Link with Sangam Literature A particularly notable aspect of the Keeladi excavation is that it provides archaeological evidence for the “urban way of life” described in Sangam literature. The artifacts found at Keeladi stand as material evidence for the urban life associated with the “Marutham” landscape type described in Sangam texts—trade, crafts, education, sophisticated architecture, and more. Museum and Public Display To preserve and display the artifacts found at Keeladi to the general public, the Tamil Nadu government has established a dedicated museum there. This offers students, researchers, and the public an opportunity to directly view Tamil Nadu’s ancient urban civilization. Importance of Continuing Research The Keeladi excavation is still ongoing. Each new phase of excavation continues to expand our understanding of Tamil Nadu’s ancient history. Archaeological experts believe that, by conducting comparative studies with other nearby sites such as Adichanallur and Kodumanal, it will be possible to create a comprehensive map of Tamil Nadu’s ancient civilization. Conclusion The Keeladi excavation stands as a major archaeological development that prompts a re-examination of Tamil Nadu’s history. Although scientific debates regarding its dating and interpretation continue, the artifacts recovered at Keeladi clearly illuminate the advanced urban life and intellectual prosperity of the people of Sangam-era Tamilakam. It is expected that, through continued scientific research, many more layers of this historical puzzle will come to light in the future. Publication: Arivuppasi Media
