when did the use of iron began in the subcontinent
Iron Age The history of metallurgy in the Indian subcontinent began during the 2nd millennium BC. Archaeological sites in India, such as Malhar, Dadupur, Raja Nala Ka Tila and Lahuradewa in present-day Uttar Pradesh show iron implements in the period 1800–1200 BC.[7] Archaeological excavations in Hyderabad show an Iron Age burial site.[38] Rakesh Tewari[39] believes that around the beginning of the Indian Iron Age (13th century BC), iron smelting was widely practiced in India. Such use suggests that the date of the technology's inception may be around the 16th century BC.[7]
