Hammir Dev Chauhan, the ruler of Ranthambore who fell in 1301, was defeated by which Sultan of Delhi?

Chand Bardai's Prithviraj Raso tells that four clans, the Pratihara, the Chauhan, the Solanki and the Parmar, rose from a fire pit at Mount Abu where the sage Vashishtha performed a sacrifice, and from this account the Agnikula or fire born theory takes its name.

Tod, who served as the Political Agent of the East India Company in western Rajputana, wrote the Annals and Antiquities of Rajasthan and argued that the Rajputs were descended from the Scythians of Central Asia, pointing to shared habits of warfare, the place of the horse and certain funeral rites.

The four clans named in the Agnikula account are the Pratihara or Parihar, the Chauhan or Chahamana, the Solanki or Chaulukya and the Parmar or Paramara.

He ruled in about the middle of the eighth century from Bhinmal in the Jalore region and is credited with stopping the Arab armies that had taken Sindh, a service which even the Rashtrakuta records acknowledge when they describe the Pratihara as the defender of the west.

Mihir Bhoja, also called Bhoja I, was the greatest of the Gurjara Pratiharas; he ruled from Kannauj in the ninth century, was a devotee of Vishnu and issued silver coins carrying the title Adivaraha, the primeval boar, one of Vishnu's forms.
