Historical Events: In the ancient time Kishoreganj area was included in the kingdom of the Kamrupa. In the 11th and 12th century the Pala, Varman and Sena kings ruled this area or part of it. After that there arose petty independent kingdoms under the Koch, Hajong, Garo and Rajbanshi. Although in 1491 AD the greater part of Mymensingh was included within the Muslim rule under Firoz Shah, Kishoreganj remained outside. Greater part of Kishoreganj was included in the Mughal Empire during the rein of the Mughal Emperor AKBAR. But some areas including Jangalbari and EGARASINDHUR remained under the Koch and Ahom kings. In 1538 AD the Ahom king of Egarasindhur was defeated by the Mughals and in 1580 the Koch Chief of Jangalbari was defeated by ISA KHAN. The episode of the conflict between the Mughal Commander Man Singh and Isa Khan, the Chief of the BARA-BHUIYANS in 1580 and the defeat of Man Singh at Egarasindhur are still current. Though after the death of Isa Khan in 1599 the grater part of Kishoreganj was still under the rule of his son MUSA KHAN who ultimately seceded to the Mughals.
