who was prutiraj singh

Prithviraja III (IAST: Pṛthvī-rāja; reign. c. 1178–1192 CE), popularly known as Prithviraj Chauhan or Rai Pithora was a king from the Chahamana (Chauhan) dynasty. He ruled Sapadalaksha, the traditional Chahamana territory, in present-day north-western India. He controlled much of the present-day Rajasthan, Haryana, and Delhi; and some parts of Punjab, Madhya Pradesh and Uttar Pradesh. His capital was located at Ajayameru (modern Ajmer), although the medieval folk legends describe him as the king of India's political centre Delhi to portray him as a representative of the pre-Islamic Indian power.

Early in his career, Prithviraj achieved military successes against several neighbouring Hindu kingdoms, most notably against the Chandela king Paramardi. He also repulsed the early invasions by Muhammad of Ghor, a ruler of the Muslim Ghurid dynasty. However, in 1192 CE, the Ghurids defeated Prithviraj at the Second battle of Tarain, and executed him shortly after. His defeat at Tarain is seen as a landmark event in the Islamic conquest of India, and has been described in several semi-legendary accounts. The most popular of these accounts is Prithviraj Raso, which presents him as a "Rajput", although the Rajput identity did not exist during his time.
