During Alauddin Khalji’s military reforms, cavalry obligations were formalised: soldiers were classified as Yak Aspa (one-horse) or Do Aspa (two-horse) depending on how many mounts they provided and their specific duties. This system allowed the state to organise cavalry strength precisely, determine required remount provisions and allocate pay and rations accordingly. The classification helped in recruitment standards, logistical planning and tactical deployment, contributing to the increased efficiency and reliability of Alauddin’s cavalry forces.
