Hariraja (r. c. 1193–1194 CE) was a king from the Chauhan (Chahamana) dynasty who ruled parts of his ancestral kingdom (in present-day Rajasthan, India) for a brief period, before being defeated by the Ghurids.
He and his elder brother Prithviraja III were born in Gujarat, where their father Someshvara was brought up at the Chaulukya court by his maternal relatives.
[1] Prithviraja ascended the Chahamana throne after Someshvara's death, but his reign ended in 1192 CE with a Ghurid conquest of the kingdom.
[2] Hariraja revolted against the Ghurid rule in the Chahamana capital Ajmer, forcing Govindaraja to take shelter in the Ranthambore Fort.
Hammira Mahakavya by the Jain scholar Nayacandra Suri also states that Hariraja had to fall back to Ajmer, where he determined that any further resistance against the Ghurids was fruitless.
