 Maharaja Sawai Jai Singh (3 November 1688 – 21 September 1743) was the Hindu Rajput ruler of the kingdom of Amber (later called Jaipur). He was born at Amber, the capital of the Kachwahas. He became ruler of Amber at the age of 11 after his father Maharaja Bishan Singh died on 31 December 1699. He was given title of Sawai by the Mughal Emperor, Aurangzeb in the year 1699, who had summoned him to Delhi, impressed by his wit. Later he proved to be Sawai also in warfare. On 21 April 1721, the Mughal emperor Muhammad Shah bestowed upon him the title of Saramad-i-Rajaha-i-Hind and on 2 June 1723, the emperor further bestowed him the titles of Raj Rajeshvar, Shri shantanu ji and Maharaja Sawa .
