The Kumbhalgarh was built and ruled by Kumbha and his dynasty who were Sisodia descendents.
Kumbhalgarh in its present form was developed by, and said to be personally designed by Rana Kumbha. Rana Kumbha's kingdom of Mewar stretched from Ranthambore to Gwalior and included large tracts of erstwhile Madhya Pradesh as well as Rajasthan. Out of the 84 forts in his dominion, Rana Kumbha is said to have designed 32 of them, of which Kumbhalgarh is the largest and most elaborate.
Kumbhalgarh also separated Mewar and Marwar from each other and was used as a place of refuge for the rulers of Mewar at times of danger. A notable instance was in the case of Prince Udai, the infant king of Mewar who was smuggled here in 1535, when Chittaur was under siege. Prince Udai who later succeeded to the throne was also the founder of the Udaipur City. The fort remained impregnable to direct assault, and fell only once, due to a shortage of drinking water, to the combined forces of Mughal Emperor Akbar, Raja Man Singh of Amber, Raja Udai Singh of Marwar, and the Sultan of Gujarat.
The fort is self-contained in all respect to withstand a protracted siege. Its defences could be breached only once by the combined armies of the Mughal and of Amber primarily for scarcity of drinking water. There is a magnificent array of temples built by the Mauryas of which the most picturesque place is the Badal Mahal or the palace of the clouds. The fort also offers a superb birdís eye view of the surroundings. The fort's massive wall stretches some 10 kms with a width enough to take many horses abreast. Maharana Fateh Singh renovated the fort in the 19th century. The fort's large compound has very interesting ruins and a walk around it can be very educative.
