Jayatasimha was the son of his predecessor
Kelhanadeva. As a prince, he assisted his father in administration. After Kelhanadeva's death, Jayatasimha ascended the throne of Naddula, while his brother Sodhaladeva ruled the province of
Mandavyapura. An 1194 CE
Sadri inscription shows that he assumed the title
Maharajadhiraja. By the mid-1190s CE, the Muslim
Ghurid dynasty had defeated the
Chahamanas of Shakambhari in north, gaining control of their capital
Ajmer. In 1197 CE, the Ghurid general
Qutb al-Din Aibak launched a southern expedition from Ajmer. According to the 13th century Muslim historian
Hasan Nizami, by the time Qutb al-Din reached Nandul (Naddula), he found the fort abandoned. A confederacy of local Hindu rulers assembled at
Mount Abu to oppose him, but Qutb al-Din defeated them. Jayatasimha appears to have been one of these Hindu rulers. Historian R. B. Singh identifies him with Rai Karan, who is said to have escaped after the defeat.
Dasharatha Sharma believes that he might have been one of the rulers who were killed or taken prisoner. After Jayatasimha, the Naddula kingdom disintegrated into several principalities. According to an
Achaleshvara inscription, the
Guhila ruler
Jaitrasimha destroyed Naddula and defeated the Turushkas. According to historian R. B. Singh, this suggests that the Ghurids had captured Naddula, and
Jaitrasimha defeated their local governor. Later, the
Jalor Chahamana king
Udayasimha (a relative of Jayatasimha), gained control of Naddula. However, historian D. C. Ganguly believes that
Jaitrasimha may have plundered Naddula
after Udayasimha's conquest of Jalore.
G. H. Ojha and Dasharatha Sharma theorize that Jayatasimha was succeeded by
Maharaja Samantasimha, who is attested by five inscriptions dated 1199-1201 CE. == References ==
