Prithviraj Chauhan III was the last of the great Chauhan rulers of Ajmer who left a deep imprint in the sands of time and redefined the concept of valour in its noblest form.
Prithviraj Chauhan III came from a distinguished line of rules who had elevated Ajmer to the position of the premier power in north Indian when even the Tomar rulers of Delhi paid homage to them. Prithviraj was the son of Someshwara who died in 1179 A.D.
Build in the 7th century by Ajaipal Chauhan, the fort gives a birds eye view of the city. Taragarh fort or the 'Star fort' is situated on a hill and to reach there one has to take winding bridle path.
Another alliance with the Chauhan was forged through the marriage of Pajjuna with a sister of Prithviraj III of Delhi as recorded in the chronicles of the Prithviraj Raso. Raja Pradhyumn Singh or Pajjuna fought valiantly alongside (his brother in law), Prithviraj Chauhan. At the time of Swayamvar of Samyogita at Kannauj in 1185, Pajjuna was trusted general of Prithviraj chauhan III. When Samyogita garlanded the statue of Prithviraj Chauhan, Prithviraj came out from his refuge and took the Samyogita with him. Jaichand of Kannauj ordered his forces to pursue Prithviraj, but the forces were stopped and engaged in a battle with Pajjuna. Thus Prithviraj III was able to reach safety in his capital.
In this battle Pajjuna, his three brothers Palansi, Jaitsi, and Kansi and two sons Balbhadra, Bhinvsi were killed. Pajjuna is believed to have been killed in the Second Battle of Tarain in 1192. Following the capture and death of Prithviraj Chauhan, Pajjuna's son Malaya Si succeeded his father having fought bravely and suffered wounds in the battle with which his father and brothers lost their lives. The Kachwahas remained a threat to the neighboring Islamic Sultanate of Delhi, their kingdom also stood on major trade and (Islamic) pilgrimage routes leading to the shrines of Ajmer and the ports of Gujarat.
