Prithviraj Singh I
Prithviraj Singh I, also known as Prithvi Singh I, was a 16th-century Rajput ruler of Amber. He was a monarch of strong religious inclinations and during his reign, Amber became increasingly politically active. He took part in the Rajput alliance against the Mughal emperor Babur, fighting against the latter in the Battle of Khanwa alongside Rana Sanga of Mewar in 1527. Three of Prithviraj's sons successively followed him as ruler of Amber, with many of his descendants also populating the kingdom's highest aristocracy in subsequent centuries.
Reign
Prithviraj ascended the throne of Amber after the death of his father, Raja Chandrasen, in 1503. With his rule, Amber, which had been experiencing a long period of stagnation, was revitalised, entering an era of extensive political activity. This may be shown through his marriage to a Mewari princess, to whose house the rajas of Amber owed homage.Prithviraj was a fervent devotee of the Hindu deity Krishna, taking as his spiritual teacher an ascetic who took the name Krishna-das. This guru bestowed on the Raja two sacred idols; Narasimha, which has a temple in Amber, and Sitaram, which has one in Jaipur. The latter idol was from then on carried at the head of the Amber army in battle. At one point, Prithviraj made a pilgrimage to Dwarka, where he was initiated as a monk in the monastery.
In March 1527, he, alongside his son Jagmal and a number of relations, fought under Rana Sanga of Mewar in the Battle of Khanwa against the Mughal emperor Babur. This was the last of the great battles fought by the Rajputs, during which Sanga was debilitated after being struck by an arrow. Prithviraj, alongside Rao Maldev of Marwar and Rao Akheraj of Sirohi, escorted the injured Sanga to safety.
