The First Battle of Tarain (Taraori) was fought between Sultan Mohammad Ghori and Prithviraj Chauhan in 1191 near the town of Tarain in Haryana. The army of Mohammed Ghori was defeated by the Rajput army of Chauhan.
Details: The Western Punjab was already annexed by Mohammed Ghori. The provinces of Eastern Punjab were within the control of Prithviraj Chauhan. As an initial step, Mohammed Ghori stormed the strategic fortress of Bathinda, which was situated within the dominion of Prithviraj Chauhan.
The fall of the fortress of Bathinda awakened Prithviraj to the gravity of the strong Mohammed’s invasion. He promised revenge and set out with an army against Mohammed. The Rajput army completely dominated the battle. In the first battle of Tarain in 1191 A.D, Prithviraj routed the Gurid army by the prowess of his arms.
Conclusion: Mohammed Ghori was badly injured and fled from the battleground. The victory at Tarain was the last flicker of the extinguishing lamp of Hindu valor. Prithviraj followed up his success by taking possession of the fort of Bathinda from the invaders.
