Jayasimha Siddharaja

Jayasiṃha (r.  c. 1092 – c. 1142), who assumed the title Siddharāja (pronunciation^ⓘ), was an Indian king who ruled western parts of India. He was a member of the Chaulukya (also called Solanki) dynasty.

Jayasimha's capital was located at Anahilapataka (modern Patan) in present-day Gujarat. Besides large parts of Gujarat, his control also extended to parts of Rajasthan: he subdued the Shakambhari Chauhans king Arnoraja, and the former Naddula Chahamana ruler Asharaja acknowledged his suzerainty. Jayasimha also annexed a part of Malwa (in present-day Madhya Pradesh) by defeating the Paramaras. He also waged an inconclusive war against the Chandela king Madanavarman.

Jayasimha's daughter Kanchana married Arnoraja. The couple's son Someshvara (the father of Prithviraj Chauhan) was brought up by Jayasimha at the Chaulukya court.
