Jaichand''s days, a rival Rajput clan had established itself in Delhi (Pithoragarh). The ruler there was Prithviraj Chouhan.
Pritiviraj was a romantic, chivalrous and an extremely fearless person. After ceaseless military campaigns, Pritiviraj extended his original kingdom of Sambhar (Shakambara) to Rajasthan, Gujarat, and Eastern Punjab. He ruled from his twin capitals at Delhi and Ajmer. His fast rise caught the envy of the then powerful ruler Jaichandra Gahadwala and there was a lot of ill-feeling between the two.
Sanyogita, the daughter of Jaichandra Gahadwala fell secretly in love with Prithiviraj and she started a secret poetic correspondence with him. Her father the haughty Jaichandra got wind of this and he decided to teach his daughter and her upstart lover a lesson. So he arranged a Swayamwara (a ceremony where a bride can select her husband from the assembled princes. She had the right to garland any prince and she became his queen. This is an ancient Hindu custom among Royalty). Jaichandra invited all the big and small princes of the country to Kannauj for the royal Swayamwara. But he deliberately ignored Prithiviraj. To add insult to injury, he even made a statue of Prithiviraj and kept him as a dwarpala ( doorman). Prithviraj got to know of this and he confided his plans to his lover. On the said day, Sanyogita walked down the aisle where the royale had assembled and bypassed all of them only to reach the door and garland the statue of Pritiviraj as a doorman. The assemblage was stunned at this brash act of hers. But what stunned them and her father Jaichandra was the next thing that happened. Prithiviraj who was hiding behind the statue, also in the garb of a doorman, whisked Sanyogita away and put her up on his steed to make a fast getaway to his capital at Delhi. Jaichandra and his army gave earnest chase and in the resultant string of battles between the two kingdoms fought between 1189 and 1190, both of them suffered heavily. While this drama was being enacted, another ruler also named Mahmud who was from Ghori in Afghanistan had grown powerful and had captured Ghazni and subsequently attacked the Ghaznavid Governor of Punjab and defeated him. The kingdom of Mahmud Ghori now stretched up to the domains of Prithiviraj Chouhan. A clash was inevitable. Mahmud Ghori threw the gauntlet by laying siege to the fortress of Bhatinda in East Punjab which was on the frontier of Prithiviraj''s domains. Prithviraj''s appeal for help from his father-in-law was scornfully rejected by the haughty Jaichandra. But undaunted Prithviraj marched on to Bhatinda and met his enemy at a place called Tarain (also called Taraori) near the ancient town of Thanesar. In face of the persistent Rajput attacks, the battle was won as the Muslim army broke ranks and fled leaving their general Mahmud Ghori as a prisoner in Pritiviraj''s hands. Mahmud Ghori was brought in chains to Pithoragarh - Prithviraj''s capital and he begged his victor for mercy and release. Prithviraj''s ministers advised against pardoning the aggressor. But the chivalrous and valiant Prithviraj thought otherwise and respectfully released the vanquished Ghori.
