Bundi is a district in the state of Rajasthan in western India. The city of Bundi is the district headquarters. It has an area of 5,550 km2 and a population of 1,110,906 (2011 census). It is divided into 5 tehsils which are: Bundi, Hindoli, Nainwa, Keshoraipatan and Indergarh. Bundi district is located in southeastern Rajasthan, in the region of Hadoti. It borders Tonk district to the north, Bhilwara district to the west, Chittorgarh district to the southwest, and Kota district to the east. The Chambal River marks the southeastern border dividing Bundi and Kota districts. A double range of hills (parallel and close together) crosses Bundi district from northeast to southwest, dividing the district into two almost equal parts. The southern face of this range is a steep escarpment which makes crossing difficult. There are four passes through the hills. One of them is at the city of Bundi, and the road from Deoli to Kota passes through here. Another is immediately to the east, at Jainiwas; a direct road to Tonk passes through here. The third pass, between Khatgarh and Ramgarh, is a gorge cut by the Mez river. The fourth pass is near the town of Lakheri. The plains northwest of the hills are drier, and their soil is relatively hard and stony. The southeastern plains have a wetter climate and more fertile soil, including rich alluvial soil along various streams and fertile, sandy loam in various other places. Stone Age tools dating around 5,000 to 200,000 years before present, were found in Bundi and Bhilwara districts of the state. South-east Region of Rajasthan is known as Hadoti - the land of the Hada Rajputs. Hadas are a major branch of the Chauhan Agnikula Rajputs (hailing from fire dynasty). They had settled in the hilly terrain of Mewar, at Bambaoda, near Bijoliya in the 12th century CE. Bundi was established in 1241 CE by Rao Deva Singh. This was the first step in the establishment of Hadauti, when the Hadas moved down from the ‘Pathar’ around Bambaoda. Bundi takes its name from the Bando Naal or the narrow passage, between the rugged hills.
