Chauhaan Vansh is said to rule in Raajasthaan, near Ajamer. Prithveeraaj Chauhaan, the most famous ruler of Chauhaan Vansh ruled from 1180-1192. His father's name was Someshwar (died in 1179) and his mother's name was Karpooree Devee. He was the last Hindu ruler of India.

He did Sanyogitaa Haran, as Sanyogitaa (daughter of Jayachand) wanted to marry Prithveeraaj. Since Jayachand did not want to marry her to him, at the time of her Swayamvar, he kept a statue of Prithveeaaj at the door of the Swayamvar place. So when Sanyogitaa's Swayamvar was taking place, she put her Jayamaalaa in the neck of Prithveeraaj Chauhaan's statue in the absence of Prithveeraaj Chauhaan. It is said that prithviraaj Chauhaan came out from behind the statue, took Sanyogitaa from her Swayamvar hall, made her sit on his horse and fled away.

"Prithveeraaj Vijaya" of Jayanak; and "Prithveeraaj Raaso" of Chand Bardaayee poets have immortalized the deeds of Prithveeraaj Chauhaan in their works.
