TN Government has released a report titled, ‘Antiquity of Iron: Recent Radiometric Dates from Tamil Nadu’.
The discovery was made through the radiometric dating of burial urn samples from Sivagalai in Thoothukudi district.
The study has revealed that the Iron Age may have begun in present-day Tamil Nadu as early as 3,345 BCE.
The new findings push the introduction of iron in the Tamil landscape back 5,300 years.
The discovery suggests that a contemporary Iron Age civilization existed in the southern India at the same time as the Indus Valley Civilization in northern and northwestern India.
Before these discoveries, the earliest iron objects in Tamil Nadu were dated to around 2172 BCE from Mayiladumparai in Krishnagiri district.
Additionally, another site, Adichanallur in Thoothukudi district, had produced a charcoal sample associated with iron objects that was dated to 2517 BCE.
In comparison, the iron objects from other regions of India, such as Brahmagiri in Karnataka and Gachibowli near Hyderabad, were dated to around 2140 BCE and 2200 BCE, respectively.
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.
