Raja Ganesha
Raja Ganesha was a zamindar ruler and the first Hindu Sultan of the Bengal Sultanate, who took advantage of the weakness of the first Ilyas Shahi dynasty and seized power in Bengal. Contemporary historians of the medieval period considered him a usurper. The Ganesha dynasty founded by him ruled over Bengal from 1415 to 1435. His name is mentioned in the coins of his son, sultan Jalaluddin Muhammad Shah, as Kans Jha or Kans Shah. The Indo-Persian historians mentioned his name as Raja Kans or Kansi. A number of modern scholars identified him with Danujamardanadeva, but this identification is not universally accepted. In the Arakanese accounts and also in Bengal and Mithila history, it is noticed that Raja Ganesha, along with his friend, Shiva Simha Singh of Mithila had combined their forces and defeated Ibrahim Sharqi of Jaunpur Sultanate, who invaded Northern-Eastern India, which created Bengal-Jaunpur conflict.
Early life
According to the Riaz-us-Salatin, Raja Ganesha was a landlord of Bhaturia and according to Francis Buchanan Hamilton, he was the Hakim of Dinajpur in the northern Bengal. In a contemporary letter, he was described as a member of a landholder family of 400 years' standing. Later, he became an officer of the Ilyas Shahi dynasty rulers in Pandua. According to a very late authority, the Riaz-us-Salatin, he killed Sultan Ghiyasuddin Azam Shah, but the earlier authorities like Firishta and Nizam-ud-Din Ahmad do not refer to any such event, and probably he died a natural death. Ghiyas-ud-Din Azam Shah was succeeded by his son Saifuddin Hamza Shah and the latter by Shihabuddin Bayazid Shah. Firishta says that he became very powerful during the rule of Shihabuddin Bayazid Shah.While the earlier authorities like Firishta and Nizam-ud-Din say that Ganesha ascended to the throne after the death of Shihabuddin but again the Riaz-us-Salatin says that he killed Shihabuddin and seized the throne. Shihabuddin was succeeded by his son Ala-ud-din Firuz Shah but he was soon deposed by Raja Ganesha.
Reign
According to Firishta, The reign of Raja Ganesha was marked by his conciliatory policies toward the Muslims in Pandua. He mentioned that, "although Raja Ganesha was not a Muslim, he mixed freely with them and had so much love for them that some Muslims, witnessing to his faith in Islam, wanted to bury him in the Islamic manner." But according to the Riaz, soon after he took over the power in Pandua, he oppressed the Muslims of Bengal and slew a number of them. 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. Purport of this letter is found in a letter written by Ashraf Jahangir Simnani, a Sufi shaikh of Jaunpur. 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. Mulla Taqyya gives the date of this event as 805 AH, which is obviously wrong, but there may be some truth in his statement about the alliance of Sivasimha with Raja Ganesha.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.
The earlier accounts of the invasion of Ibrahim Shah Sharqi are different from the account given in the Riaz. A Chinese source mentioned that a kingdom to the west of Bengal had indeed invaded, but desisted when placated with gold and money. Abd-ur Razzaq Samarqandi, in his Maṭla'-us-Sadain wa Majma'-ul-Bahrain mentioned that in 1442, a diplomat in the service of Shah Rukh, the Timurid ruler of Herat, wrote that his master had intervened in the Bengal-Jaunpur crisis at the request of the sultan of Bengal, "directing the ruler of Jaunpur to abstain from attacking the King of Bengal, or to take the consequences upon himself. To which intimidation the ruler of Jaunpur was obedient, and desisted from his attacks upon Bengal". A contemporary Arakanese tradition recorded that the army of Raja Ganesha, then firmly in control of Pandua, had defeated Ibrahim in battle. According to this tradition, one of the rulers of Arakan, Suleiman Shah, who had been given refuge in Pandua after having been defeated by a Burman monarch in 1406, gave Raja Ganesha the military advice that enabled his army to defeat Ibrahim. After the war with Jaunpur, Raja Ganesha turned his attention to internal affairs, declining to support Deva movements, refusing Hindu restorations.
