Tomb of Qutab ud din Aibak lahore| First muslim king of Lahore.
Aibak was one of the generals of the Ghurid army that were defeated by the forces of the Chahamana ruler Prithviraja III at the First Battle of Tarain in India.[8] At the Second Battle of Tarain, where the Ghurids emerged victoriously, he was in charge of the general disposition of the Ghurid army and kept close to Sultan Muhammad Ghori, who had placed himself at the centre of the army.

After his victory at Tarain, Muhammad Ghori assigned the former Chahamana territory to Aibak, who was placed at Kuhram (present-day Ghuram in Punjab, India).[10][4] The exact nature of this assignment is not clear: Minhaj describes it as an iqta', Fakhr-i Mudabbir calls it a "command" (sipahsalari), and Hasan Nizami states that Aibak was made the governor (ayalat) of Kuhram and Samana.

After the death of Prithviraja, Aibak appointed his son Govindaraja IV as a Ghurid vassal. Sometime later, Prithviraja's brother Hariraja invaded the Ranthambore Fort, which Aibak had placed under his subordinate Qawamul Mulk. Aibak marched to Ranthambore, forcing Hariraja to retreat from Ranthambore as well as the former Chahamana capital Ajmer.
