In 1197, Aibak defeated the Chaulukya army at Mount Abu, thus avenging Mu'izz ad-Din's defeat at the Battle of Kasahrada nearly two decades earlier. Aibak's army then marched to the Chaulukya capital Anhilwara: the defending king Bhima II fled the city, which was plundered by the invaders. Minhaj characterizes Aibak's raid of Anhilwara as "conquest of Gujarat", but it did not result in annexation of Gujarat to the Ghurid Empire. The 16th century historian Firishta states that Aibak appointed a Muslim officer to consolidate the Ghurid power in the region, while Ibn-i Asir states that Aibak placed the newly-captured territory under Hindu vassals. Whatever the case, the Ghurid control of the region did not last long, and the Chaulukyas regained control of their capital soon after.
