Prithviraj Chauhan
Prithviraj Chauhan was born at Ajaymeru (Ajmer) in 1166 A.D. His father was Someshwar Chauhan and mother Karpuri Devi, a Kalachuri (Chedi) princess, daughter of Achalaraja of Tripuri.
Muhammad Ghori attacked India multiple times. First time he was routed in present day Gujarat by Rajputs. Mularaja-II was not even a teen yet and his mother organized the defences of Pattan. Battle was fought at Kayadara near Mount Abu, in 1178 A.D. and Ghori was resoundingly defeated. After this defeat he never entered India through Gujarat. In first battle of Taraori in 1191 Prithviraj Chauhan's cavalry charged and routed the Ghurid cavalry and captured Ghori. Ghori begged for his life. Prithviraj allowed him to go despite his generals asking him not to do so.
