A massive territory to the west of the Chahamana dynasty was ruled by Muhammad of Ghor, who wanted to expand his empire towards the east. In order to do so, Muhammad of Ghor had to defeat Prithviraj Chauhan and hence, he waged a war against the Chahamanas. Though many legends claim that Prithviraj and Muhammad of Ghor fought many battles, historians confirm that at least two battles were fought between the two. Since they were fought near the town of Tarain, they later came to be known as ‘Battles of Tarain.’
