About Iron Age
- The iron age is the period of human history (pre-history) where iron became a regular metal to be used by the masses.
1. North India:
- For North India, the early evidence suggests iron use around 1800 BCE. The Iron age likely began from the 1200 BCE i.e., after the Bronze Age. (Rakesh Tiwari, 2003)
- Iron artefacts, furnaces, and tuyeres, carbon-dated between 1800 BCE and 1000 BCE, were found during the excavations conducted at Raja Nala-ka-tila , Malhar, and Dadupur archaeological sites in Uttar Pradesh.
- In Malhar, especially, the presence of tuyeres, slags, and finished iron artefacts, hinted at a large-scale manufacturing of iron tools.
- Technical studies on materials found at several places suggested that iron smelting in India could have begun as early as the 16th century BCE.
- Iron age in North India co-existed with Painted Grey Ware (1300-300 BCE) and Northern Black Polished Ware (700-200 BCE) civilisations. It also coincided with the Later Vedic Period and period of Mahajanapadas.
2. South India:
- The recently released report by the Tamil Nadu State Archaeology Department, ‘Antiquity of Iron: Recent radiometric dates from Tamil Nadu’, has placed the introduction of the iron age at 3,345 BCE to 2,953 BCE (fourth millennium BCE) in the State.
- The report suggests that when cultural zones to the north of Vindhyas experienced the copper age, the south might have already entered into the iron age, owing to the limited availability of commercially exploitable copper ore.

Significance of the discovery of Iron:
- The presence of Iron helped in the development and expansion of 2nd phase of urbanisation in India (1st phase was Indus Valley civilisation).
- Iron helped in clearing forest and iron plough boosted agricultural productivity and surplus crops were produced.
- Iron age is also characterised by social stratification, polity diversification, literary developments, Economic expansion and Trade and craft specialisation.
