The Chahamanas of Jalor, also known as the Chauhans of Jalore, were an Indian dynasty that ruled the area around Jalore in present-day Rajasthan. They belonged to the Chauhan clan of Rajputs. The Chahamanas of Jalor descended from Alhana, a Chahamana king of the Naddula branch. Originally, the Jalore Fort was controlled by a branch of the Paramaras until early 12th century. The Chahamanas of Naddula seized its control during Alhana's reign. Kirtipala, a son of Alhana, received a feudal grant of 12 villages from his father and his brother (the crown-prince) Kelhana. He controlled his domains from Suvarnagiri or Sonagiri, the hill on which Jalore Fort is located. Because of this, the branch to which he belonged came to be known as Sonagara.
