INDIA, March 12, 2016 (India Today): That it existed at all was a surprise – a fortified enclosure of mud and brick, comparable to the citadels of the Harappans, spread over 500 sq m. It was filled with ash and cowdung. A people called the Ahars had built it in Balathal near modern Udaipur some 4,500 years ago.

Carbon dating established that they had lived in and around the Mewar region in Rajasthan between 3,500 and 1,800 B.C. They were Mewar’s first farmers, older even than the Harappans. But why had they built a fort only to fill it with ash and cowdung? To solve the mystery, a team of Indian archaeologists excavating the site went on removing layer after layer of civilisation.

There are 90 sites of Ahar – a rural society. The recent round of excavations is establishing that Ahar culture and Harappan civilisation were different though contemporary and related. This village life emerged much before the mature Harappan era. Ahar culture flourished predominantly in the Mewar region of Rajasthan, on the eastern side of the Aravallis, and in undulating rocky plateaus and plains along the Banas river and its tributaries.
