The discovery was made through the radiometric dating of burial urn samples from Sivagalai in Thoothukudi district, which contained both charcoal and iron objects. These new dates establish Tamil Nadu as the site of the earliest known Iron Age civilization, making it potentially the oldest in the world.
Earlier, the Hittite Empire (in modern-day Turkey) was believed to be the first civilization to use iron, with evidence dating back to around 1,380 BCE. However, according to Tamil Nadu Chief Minister M. K. Stalin, the new findings push the introduction of iron in the Tamil landscape back 5,300 years.
«We have scientifically established that iron was introduced 5,300 years ago in the Tamil landscape. The Iron Age began from Tamil land,» Stalin stated on Thursday while releasing the study Antiquity of Iron: Recent Radiometric Dates from Tamil Nadu, authored by K. Rajan and R. Sivananthan.
The samples from Sivagalai were analyzed by three prestigious research institutions: Beta Analytics in the United States, the Physical Research Laboratory in Ahmedabad, and the Birbal Sahni Institute of Palaeosciences in Lucknow. The findings were consistent across all three labs, with dates showing a significant alignment.
