When the old Raghunath Singh died in 1745, Raghuji Bhonsle, who was returning from the Bengal campaign, installed Mohansingh as the Haihaya king under his suzerainty.
Unlike his Haihaya ancestors, who solely exercised overlordship over petty chieftains, Mohansingh started successfully conquering and directly ruling over the zamindaris.
[citation needed] He was faithful and obedient to the king at Nagpur and paid regular tribute to the Bhonsle treasury.
Janoji became the king of Nagpur and given the title of Sena Sahib Suba, Sabaji was to govern Western Berar with his headquarters at Darwha, Mudhoji was given the title of Senadhurandhar with Chanda an Chhattisgarh as his jurisdiction and Bhonsle was to govern Chhattisgarh with his headquarters at Ratanpur.
Therefore Mohansingh started collecting his resources and forces near Raipur half-heartedly but he died shortly after and thus, Bimbaji assumed rule of the region with ease.
