Explanation: Prithviraj Chauhan, a prominent ruler of the Chauhan dynasty, was a significant figure in the political landscape of northern India during the late 12th century. His reign is marked by his military prowess and his conflicts with Muhammad of Ghor, a Ghurid ruler who sought to expand his empire into India.
Prithviraj Chauhan's kingdom was extensive and included parts of present-day Delhi, Haryana, and Rajasthan. His capital was Ajmer, which is located in Rajasthan, and he had control over a vast territory that extended into the regions that are now part of these states. The Chauhan dynasty was known for its strong military and administrative capabilities, which allowed Prithviraj to maintain control over a large area.
Delhi, which was a strategic location due to its central position, was under the influence of Prithviraj Chauhan. His control over Delhi was crucial for his military campaigns and for maintaining his influence over the region. The city of Delhi was an important center for trade and commerce, and its control was essential for the Chauhan dynasty's economic and political power.
Haryana, which lies between Delhi and Rajasthan, was also part of Prithviraj Chauhan's kingdom. The Chauhan dynasty's influence extended into the areas that are now part of Haryana, making it a part of his kingdom. The region was strategically important due to its fertile land and its position between the two major centers of power.
Rajasthan, the heartland of the Chauhan dynasty, was the core of Prithviraj Chauhan's kingdom. His capital, Ajmer, was located in Rajasthan, and he had control over other important cities in the region. The Chauhan dynasty's influence in Rajasthan was strong, and it was from this base that Prithviraj Chauhan launched his military campaigns and maintained his power.
The conflicts between Prithviraj Chauhan and Muhammad of Ghor were significant events in Indian history. These battles, particularly the First Battle of Tarain in 1191 and the Second Battle of Tarain in 1192, had a profound impact on the political landscape of northern India. The defeat of Prithviraj Chauhan in the Second Battle of Tarain marked the beginning of the Delhi Sultanate and the end of the Chauhan dynasty's rule over these territories.

His rule over these territories was significant and had a lasting impact on the history of northern India.
