At the time of Kumbha, maladministration prevailing in Gujarat had ended and the rulers there were eager to extend their region of influence. The continued struggle between Malwa and Mewar and the political condition of Sirohi and Gujarat made the struggle between Mewar and Gujarat inevitable.
In 1456 CE after the death of Firoz Khan, his son Shams Khan became the new master of Nagaur, but Firoz’s younger brother Mujahid Khan defeated Shams Khan and occupied Nagaur. Shams Khan reoccupied Nagaur with the help of Maharana Kumbha and shortly after this, against the conditions laid down by Kumbha, he started repair of the Nagaur fort. Angered Kumbha invaded upon Naguar and occupied it.
