As the
heir apparent, Kanhadadeva assisted his father in administration from at least 1296 CE onwards. A 1296 pillar inscription discovered at Topkhana in Jalore states that Kanhadadeva shared the burden of administration during his father's reign. The 1299 CE
Chohtan inscription also refers to the joint reign of the father-son duo. No inscription from Kanhadadeva's reign has been discovered, but the last extant inscription from his father's reign is dated 1305. Therefore, Kanhadadeva appears to have ascended the throne sometime around 1305.
Delhi Sultanate's Gujarat campaign In 1299, the
Delhi Sultanate ruler
Alauddin Khalji sent an
expedition to Gujarat led by his generals
Ulugh Khan and
Nusrat Khan. The
Kanhadade Prabandha claims that Kanhadadeva (then a prince) did not permit the Delhi forces to pass through his territory, concerned that they would "sack villages, take prisoners, molest women, oppress
Brahmanas and slay cows". The Khalji army reached Gujarat via another route in Mewar, defeated its king
Karna, and ransacked Gujarat. After its victorious campaign in Gujarat, the Delhi army passed through Jalore on its way back to Delhi. According to the 17th century chronicle
Nainsi ri Khyat, the Delhi army encamped at "Sakarana" near Jalore. The
Kanhadade Prabandha names the place as "Sirana": it can be identified with modern Sankarna. Kanhadadeva sent Kandhala Olecha and four other messengers to the Delhi commander, expressing his displeasure over their stay in his territory, after they had imprisoned Hindus and desecrated the
Somanatha temple in Gujarat. These messengers came in contact with the neo-Muslim leader Mammunshah (Muhammad Shah) and his brothers, who were planning a mutiny against the Delhi generals. Three days later, these rebel generals attacked the Delhi army's camp from one side, while Kanhadadeva's army attacked it from the other side. The rebels killed a brother of Nusrat Khan and a nephew of Alauddin, but the mutiny was completely suppressed within 4 days. The
Kanhadade Prabandha does not mention any mutiny by the Delhi soldiers, and states that the attack on the Delhi camp was led by Kanhadadeva's minister Jaita Devada. The Delhi chronicles, such as
Ziauddin Barani's
Tarikh-i-Firuz Shahi, describe the mutiny, but do not mention any Chahamana participation in the unsuccessful mutiny. Historian
Dasharatha Sharma believes that Nainsi's account, which mentions collaboration between Kanhadadeva's forces and the mutineers, is an accurate representation of the conflict. However, Nainsi inaccurately states that Alauddin personally led the Delhi army during this campaign, and that he was present at the time of the mutiny. Therefore, historian
Kishori Saran Lal also doubts the veracity of the rest of Nainsi's account including the claim that the Jalore army aided the mutiny.
Somanatha idol The
Kanhadade Prabandha and
Nainsi ri Khyat also credit Kanhadadeva with rescuing the Somnath temple idol from desecration by the Delhi army. This claim also occurs in
Ranamalla Chhanda (1408–1411) by Shridhara Vyasa. According to these texts, Kanhadadeva's army liberated several Hindu prisoners, and recovered the Somnath idol, which was being taken to Delhi to be desecrated. Kanhadadeva is said to have installed the five fragments of this idol at
Prabhas Patan,
Bagada,
Abu, Jalor and his personal garden. The
Kanhadade Prabandha hails him an incarnation of
Krishna for this act. However, other sources state that the idol was taken to Delhi; these sources include Amir Khusrau's
Khazainul-Futuh, Barani's
Tarikh-i-Firuz Shahi and Jinaprabha's
Vividha-tirtha-kalpa. It is possible that the story of Kanhadadeva's rescue of the Somnath idol is a fabrication by the later writers. Alternatively, it is possible that the Khalji army was taking multiple idols to Delhi, and Kanhadadeva's army retrieved one of them.
Asylum to the rebels Nainsi ri Khyat further claims that Mammushah (Muhammad Shah) and his brother Gabharu, who had rebelled against the Delhi generals, took asylum with Kanhadadeva. However, Kanhadadeva disapproved of their killing of cows (which are
sacred to Hindus). Therefore, the two rebels left Jalore, and sought shelter with
Hammiradeva at
Ranthambore. == Defeat against Alauddin Khalji ==
