The Ghurid conquest of Khorasan was a successive battle between Ghurids empire and the Khwarazmian Empire which took place in Khorasan between 1200—1201.[1] After the death of Ala al-Din Tekish in 1200, his son Alā' al-Din Muhammad succeeded him. Upon this, Ghiyath al-Din requested his brother, Muhammad of Ghor, to make preparations from India to attack the Khawarazmians. Muhammad of Ghor arrived from India with a large army, including elephants.[2] Now prepared, Ghiyath al-Din and Muhammad of Ghor entered Khorasan with their army, capturing Nishapur, Merv, Sarakhs, Tus. The Ghurid forces expanded as far as Gorgan and Bistam.[3] Kuhistan, a stronghold of Isma'ilis, was also campaigned against by Muhammad of Ghor, where their holdings were plundered, leading to all of Khorasan being brought under Ghurid control.[3]
