[8] According to the Riaz-us-Salatin (a chronicle written in 1788), Raja Ganesha was a landlord of Bhaturia and according to Francis Buchanan Hamilton he was the Hakim (governor) of Dinajpur[9] in the northern Bengal.

Thereupon, a Muslim Shaikh Nur Qutb Alam wrote a letter to the Jaunpur Sultan, Ibrahim Shah Sharqi, with an appeal to invade Bengal and overthrow Raja Ganesha.

According to a tradition, recorded by Mulla Taqyya, a courtier of Akbar and Jahangir, Ibrahim Shah, while proceeding to overthrow Raja Ganesha, was opposed by Sivasimha, the ruler of Oiniwar Dynasty Mithila.

[13] According to the narrative given in the unreliable Riaz, when Ibrahim Shah reached Bengal with his army, Ganesha defeated Shaikh Nur Qutb Alam .

But many independent sources confirm that Ibrahim Shah was thoroughly defeated by Raja Ganesh, such as Chinese memoirs of that time, Arakan and Burmese histories as well as the ambassador of the Timurid ruler of Afghanistan.

[14] In 1922, a modern scholar, Nalini Kanta Bhattasali assumed in his Coins and Chronology of the Early Independent Sultans of Bengal, that, Danujamardanadeva, who issued silver coins in Saka era 1339-40 (1416–18) from Suvarnagrama, Pandunagara and Chatigrama with the Sanskrit legend, Shri Chandi Charana Parayana (devoted to the feet of Goddess Chandi) in Bengali script on the reverse, is actually a title of Raja Ganesha.

[3] But Ahmad Hasan Dani regarded Danujamardanadeva and Mahendradeva as the local chiefs in East and South Bengal who asserted independence during troubles caused by the capture of power by Raja Ganesha and the invasions of Ibrahim Shah Sharqi.

[6] He, on the basis of the testimony of later oral and literary sources, identified Danujamardanadeva and Mahendradeva as the descendants of the Deva dynasty kings of Chandradvipa (the present-day Barisal district).

Another modern scholar, Richard Eaton supported his view and identified the mint town Pandunagara with Chhota Pandua in the present-day Hooghly district.
