He was one of the Chiefs of Raja Man Singh ruler of Jodhpur, and Diwan of his predecessors Vijay Singh and Bhim Singh. The engagement of princess Krishna, beautiful daughter of Rana Bhim Singh of Udaipur had been finalised with Bhim Singh predecessor of Man Singh.
Since he died before marriage, her hand was engaged with Jagat Singh, ruler of Jaipur, Under the influence of his courtiers, Man Singh wrote to Jagat Singh to break the relation in order that he could marry with Krishna who was earlier engaged to his predecessor. On refusal of the proposal by Jagat Singh he attacked Jaipur.
To his surprise his chiefs who had inspired him for that all and the Rao of Bikaner joined the Jaipur ruler alongwith their armies. Defeated Man Singh fled to Bisalpur. One of his Jain employees Chainmal Singhvi, however, advised him to go back to Jodhpur for the safety of his life and the state.
On coming back to Jodhpur, of doubtful nature, Man Sing turned out from service even some of the loyal courtiers and chiefs including Indraraj Singhvi. At this critical time of Man Singh, Jagat Singh attacked and beseiged Jodhpur with his big army.
Indraraj and some other loyal chiefs were though unhappy over Man Singh’s acts but they were fully loyal to their Jodhpur State. Then in the army of Jagat Singh, Indraraj studied the strategies and persuaded Pindari Amir Khan to separate himself from Jagat Singh. They both quickly mobilised more army and attacked Jaipur.
Stunned with this unexpected development Jagat Singh rushed back to save his capital. Defeated by the army of Indraraj in the way he returned to Jaipur. Indraraj had recovered from him all the looted wealth and received a hearty welcome from repenting Man Singh.
In recognition of his bravery and loyalty to Jodhpur State, Man Singh appointed him his Chief Commander, To take revenge from the ruler of Bikaner, who had joined Jagat Singh in the attack over Jodhpur, Man Singh attacked Bikaner with a big army commanded by Indraraj.
They defeated the Bikaner ruler in the battle at Bapri and later at Gajner and got as compensation the pargana of Phalaudi and wealth worth rupees two lakhs. Greatly happy Man Singh much praised Indraraj and gave him more administrative powers.
Courageous and loyal Indraraj, however, could not save himself from the envious conspiracies of his enemies. They became successful in his murder in a fight in the fort with Pindari Amir Khan and his Pathan soldiers in 1816. Raja Man Singh had much felt the loss of the brave and loyal hero.
