He ruled the Sapadalaksha country, which included parts of present-day Rajasthan in north-western India.
He ascended the throne after killing his father Arnoraja, and ruled briefly before being dethroned by his brother Vigraharaja IV.
Jagaddeva was one of the three sons born to the Chahamana king Arnoraja and his queen Sudhava, who was a princess of Marwar.
Other texts, such as Hammira Mahakavya, Prabandha Kosha and Surjana Charita name Arnoraja's successor as Jagaddeva.
[2] Before Jagaddeva could consolidate his position, his younger brother Vigraharaja dethroned him and became the new Chahamana king.
