Keeladi Controversy

Why in the News?

  1. Keeladi has gained national attention as it is seen by many in Tamil Nadu as strong evidence of an advanced ancient Tamil civilisation.
  2. In January 2023, archaeologist Amarnath Ramakrishna submitted a report on the Keeladi excavations, highlighting findings from the Sangamera.
  3. Recently, the Archeological Survey of India (ASI) asked him to revise his report, questioning the dating and interpretation of some findings.
  4. This move has sparked controversy, with political parties in Tamil Nadu accusing the Centre of trying to undermine Tamil heritage.
Archeological Survey of India (ASI)

  1. Founded in 1861, the ASI is the premier organization for archaeological research and the protection of cultural heritage in India.
  2. It operates under the Ministry of Culture, Government of India, and manages more than 3,600 ancient monuments and archaeological sites.
  3. The ASI is responsible for excavations, conservation, and preservation of historical monuments and sites across the country.
  4. It also maintains museums and publishes research to promote awareness of India’s rich heritage.
  5. ASI works through regional circles and specialized branches, including epigraphy, prehistory, and antiquities.

Key Highlights

  1. About Keeladi Excavation
    1. Amarnath Ramakrishna, who was then the Superintending Archaeologist of the ASI, began excavations at the Pallichanthai Tidal site in Keeladi, which was originally a 100-acre coconut grove.
    2. He had shortlisted more than 100 sites along the Vaigai River for excavation, but Keeladi emerged as the most significant among them.
    3. Sophisticated urban society: In Keeladi, they found over 7,500 old objects like walls, drains, and wells, showing that an advanced city once existed there.
    4. Carbon dating showed that these findings are more than 2,160 years old, going back to the 2nd century BCE, the Sangam period in Tamil history.
  2. Significant findings
    1. No religious symbols were found at the site, suggesting that the civilisation was secular.
    2. Tamil historians and enthusiasts viewed this as strong evidence of an advanced ancient Tamil civilisation.
  3. Political Tensions
    1. The excavations were done in two phases between 2014 and 2016 by Mr. Ramakrishna.
    2. Just as the work was gaining momentum, he was transferred to Assam.
    3. Critics accused the central government of purposely slowing down the project.
    4. The Centre, which had promised funds and support, delayed both after the second phase.
    5. This led to political tension, with some claiming the Centre was trying to hide Tamil heritage.
    6. In 2017, the third phase began under archaeologist P.S. Sriraman.
    7. But after digging around 400 square meters, he reported that the earlier brick structures did not continue further.
  4. Rising Tensions
    1. The Madras High Court got involved and even visited the excavation site.
    2. It ordered the ASI to continue the work and allowed the Tamil Nadu State Department of Archaeology to join the project.
    3. In 2019, the department released a report saying Keeladi was an urban settlement from the Sangam era (6th century BCE to 1st century CE).
    4. Since then, the State Archaeology Department has led the excavations, but instead of settling things, the controversy has grown.
    5. In January 2023, Mr. Ramakrishna, who was transferred back to Tamil Nadu, submitted his report on the first two phases.
  5. The controversy
    1. Mr. Ramakrishna’s report stayed with the ASI for about two and a half years.
    2. In June 2025, the ASI asked him to revise the report.
    3. The ASI raised doubts about the dating and depth of some findings, saying the early evidence needed more analysis.
    4. But Mr. Ramakrishna refused to change his report, saying his conclusions were based on proper scientific methods.
    5. He said the timeline in the report was backed by soil layers, cultural remains, and advanced dating techniques like Accelerator Mass Spectrometry.
    6. Political parties in Tamil Nadu strongly criticised the ASI’s move, calling it an attempt to hide Tamil heritage.
    7. They claimed that the Centre was ignoring Keeladi’s importance for political reasons, not scientific ones.
    8. In response, Union Culture Minister Gajendra Singh Shekhawat said the findings lacked strong technical support and needed more scientific study.
    9. He said one report alone isn’t enough to change the entire historical understanding and more data is required.
  6. State Party’s views
    1. The AIADMK, which was in power when the Keeladi report came out, stayed quiet for a long time during the recent controversy.
    2. But in June 2025, senior leader R.B. Udhayakumar said the Centre only asked for more details to ensure “additional proof.”
    3. He also added that if the Keeladi report is rejected, the AIADMK would be the first to raise its voice in protest.
Carbon Dating

  1. Carbon dating, or radiocarbon dating, is a method used to find out the age of ancient objects that were once living, like woodbones, or seeds.
  2. It works by measuring the amount of a radioactive form of carbon (called Carbon-14) left in the sample.
  3. Since Carbon-14 slowly disappears over time, scientists can calculate how old the object is based on how much is left.
  4. This method is usually accurate for things up to about 50,000 years old.

Accelerator Mass Spectrometry

  1. AMS is a more advanced and sensitive form of carbon dating.
  2. Instead of measuring radiation, it counts the individual Carbon-14 atoms using a powerful particle accelerator.
  3. It can date much smaller samples with greater precision and is especially useful when only tiny or valuable materials are available.
  4. AMS is widely used in archaeologyenvironmental science, and even forensics.

Challenges and Way Forward

Challenges

Way Forward

Delay in accepting the original excavation report Speed up report review using independent and transparent expert committees
Allegations of political interference Ensure archaeological work remains neutral and evidencebased, free from political influence
Conflicting views on scientific methods and dating techniques Involve global experts to revalidate findings with updated and widely accepted techniques
Lack of consistent excavation efforts and shifting leadership Create a long-term, state-centre collaborative excavation plan with stable leadership
Public trust shaken due to controversy and lack of clarity Publish all findings and decisions in the public domain to maintain trust and transparency

Conclusion

This issue goes beyond a single report or excavation, it represents a broader conflict of perspectives. While the Centre emphasizes the need for scientific verification, Tamil Nadu sees it as a question of acknowledging its historical legacy. Despite the dispute, the State continues its excavations and has already opened a museum at Keeladi, attracting thousands of visitors.

Ensure IAS Prelims Question

Q. Which of the following statements about the Keeladi excavations is correct?

  1. The findings date back to the Sangam era, around the 2nd century BCE.
  2. The site revealed evidence of a secular and urban civilisation.
  3. Religious symbols were prominently found at the site.

Which of the following statements is/are correct?

  1. 1 and 2 only
  2. 2 and 3 only
  3. 1 and 3 only
  4. 1, 2 and 3

Answer: a

Explanation

Statement 1 is correct: Carbon dating and archaeological evidence suggest that the Keeladi findings belong to the Sangam era, particularly around the 2nd century BCE, revealing early Tamil urban civilisation.

Statement 2 is correct: Excavations uncovered well-planned urban structures without religious imagery, indicating that the Keeladi society was secular and focused on civic life rather than religious practices.

Statement 3 is incorrect: No prominent religious symbols were discovered at the site, which contradicts the claim; instead, the artifacts suggest a non-religious, secular urban settlement.
