Prithviraj Chauhan, was a Rajput King who controlled Delhi at the end of the 12th century, a pretty impressive warrior King, he had managed to bring most of northern India under his control by 1192, and after beating back Muslim invaders led by Mohammed Ghori at the First Battle of Tarain, it seemed as though things would be okay for him. However, he had not pursued Ghori after that first battle, which led to there being a second battle, which Prithviraj consequently lost, being killed as he tried to escape. This consequently allowed the Delhi Sultanate, and the conquest of Bengal to occur.
What I am wondering is what might the consequences be if Prithviraj had managed to defeat Ghori during the second battle of Tarain, and consequently managed to slay Ghori himself during the course of the fighting. Does the Muslim invasion of India get stuck in its tracks, will they try again? Would Prithviraj try expanding his own Kingdom?
