intersected by these meandering rivers and dotted with hills and plateaus, the state has varied natural settings of great beauty. To the north of river Shivnath there were 18 garhs belonging to the Kalchuris and to the South there were another 18 garhs belonging to the Kalchuris of Raipur. Hence, the total of these 36 Garhs (Forts) formed the basis of naming this region as Chhattisgarh. Chhattisgarh lies between 17 - 46' to 24 - 5' North and 80 - 15' to 84 - 20' East. It covers an area of 1,35,133 Sq. kms. bordering six other states - Uttar Pradesh and Jharkhand in the North, Orissa in the East, Andhra Pradesh in the South, Maharashtra in the South West and Madhya Pradesh in the North West.
Although the newly formed state came into existence on 1st November 2000, its cultural heritage is as ancient as Stone age. in ancient times Chhattisgarh was known as Dakshin Koshal. Geographical evidence of the place is found in the Ramayana and the Mahabharat. Lord Rama entered Dandkarnaya from North-East of Koshal and spent some of his exile (forest-living) period here. in Mahabharat's Rajsoo Yagya episode the description of Dakshin Koshal has been found. in historical records in Samudragupta Prayag eulogy, description of Kosal has been found. After the sixth century evidence of political insurgence of Dakshin Koshal has been found.
From Sixth Century to mid-twelve century Sarabhpurnima, Panduvanshi, Somvanshi, Kalchuri and Nagwanshi rulers dominated the region. The various documents, Copper plaques, coins, and archeological goods apprise us about the cultural heritage and political development of that time. in contemporary history evidence of ancient people has been found in the hills of Raigarh, Singhanpur, Kabra, Basnajhar, Boslada and Ongana mountains at "Chitwandongri" in Rajnandgaon district. The stone equipment made and used by ancient people have been found from the coasts of Mahanadi, Mand, Kanhar, Manihari, and Kelo River.
