Oroans: Geographical Dimension
Once Kurukhs were lived in "Indus Valley Civilization" before 2500 B.C., they lived there peacefully and sophisticated life. They were not enable to stay there, due to frequent attacks of Aryans, flood and anomalous atmosphere. They had been migrated to west coast of India at Karnatka region, M.P., than they came to Rohtashgarh of Bihar, where they made a huge fort. But here also, they could not stay a long time, because they had been driven out by the Cheroes and Afgans/Mugals. And finally they went and settled to the Chhotangpur plateau in Jharkhand state. They were divided into two flocks from Rohtasgarh, one went to the Rajmahal area in Santhal Pargran region and made their resending place at plate of river Ganga. Today they are called Malto Paharia and speak Malto. Another larger flock came to the Chhotanagpur plateau in Jharkhad state. They are Kurukhs.
Presently they are living in Bihar, Jharkhand, Chhattisgarh, West Bangal, Assam, Andaman & Nicobar island, Tripura, U.P. and Orissa states of India. They are found in Bhutan, Nepal, Bangladesh Srilanka and Marisus countries of the world. A kurukh scholar Dr. Nirmal Minz, former principal of Gossnar Collage Ranchi, expressed -"Kurukh tribal people besides Chhotanagpur, largely found in Kurus countary (today it is called Sasaram area in Bihar and the area of Rohtashgarh), Khusra, Doyrasha, Panary, Dori, Chhechhari, Nawagarh, Biru, Barwe, Gangpur, Banai Bangla, Sambalpur, Rajgangpur, Manoharpur, Jashpur, Raigarh, Surguja, Pargana and minor at Chakardharpur, Chaibasa, old Purnia, Champaran, Duwars in West Bangal, Jalpaiguri and at Dhinajpur and nearest area of Bangla Desh.
