There is a great village of the Chauhan clan by the name of Amin near Thanesar in Haryana. These Chauhans belong to the Ror community and they have provided many Volleyball players to the Indian national team. The average height of the ROR Chauhans of Amin is well over six feet. Amin is also supposed to be the village where the Pandavas arrayed their forces before the last battle in the war of Mahabharat.
According to the Rajput bards, the Chauhan is one of the four Agnikula or 'fire sprung' clans who were created by the gods in the anali kund or 'fountain of fire' on Mount Abu to fight against the Asuras or demons. Chauhan is also one of the 36 (royal) ruling races of the Rajputs.
Chauhan dynasties established themselves in several places in Northern India and in the state of Gujarat in Western India. Inscriptions also associate them with Sambhar, the salt lake area in the Dhundhar region. Sakhambari branch remained near lake Sambhar and married into the ruling Gurjara-Pratihara, who then ruled an empire in Northern India.
The Chauhans later asserted their independence from the Pratiharas, and in the early eleventh century, the Sakhambari king Ajaya-Raja founded the city of Ajayameru (Ajmer) in the southern part of their kingdom, and in the mid twelfth century, his successor Vigraharaja enlarged the state, captured Dhilika (the ancient name of Delhi) from the Tomaras and annexed some of their territory along the Yamuna River, including Haryana and Delhi.
In 12th century the Chauhans dominated Delhi, Ajmer, Ranthambhor. They were also prominent at Godwar in the southwest of Rajputana, and at Hadoti (Bundi and Kota) in the east. Chauhan politics were largely campaigns against the Chalukyas and the invading Muslim hordes.
The Chauhan kingdom became the leading state and a powerful kingdom in Northern India under King Prithviraj III (1165-1192), also known as Prithviraj Chauhan or Rai Pithora. Prithviraj III has become famous in folk tales and historical literature as the Chauhan king of Delhi who resisted the attack by Muslim ruler Mohammed of Ghor at the first Battle of Tarain (1191). Armies from other Rajput kingdoms, including Mewar, assisted him. The Chauhan kingdom collapsed after Prithviraj was defeated by Mohammed of Ghor in 1192 at the Second Battle of Tarain.
Prithviraj's defeat and capture at Tarain ushered in Muslim rule in North India by the Delhi Sultanate. The Chauhans remained in Ajmer as feudatories of Muhammad of Ghor and his successors, the Sultans of Delhi, until 1365, when Ajmer was captured by the rulers of Mewar.
A branch of the Chauhans, led by Govinda, the grandson of Pritviraj III, established themselves as rulers of Ranthambore from the thirteenth to the fifteenth centuries, until Ranthambore was captured by Rana Kumbha of Mewar.
The Hadas,great dynasty of the Chauhans, moved into the Hadoti region in the twelfth century, capturing Bundi in 1241 and ruled there until the twentieth century. One sept of these Hada Rajputs won Kota and ruled their till the merger of state in independent India.
In western India Chauhans are found at Devgadh Baria, founded by Dungarsinhji, a member of the Khichi Chauhan clan about 700 years ago.
Rajkumar (Bhadaiyan State of Awadh, UP) and Bachgoti (Diyara State of Awadh, UP) are two other branches of Chauhans (both are primarily in Uttar Pradesh). Dhauhan's are also found in Khurja Dasheri and Arnia.
