Historical events The anti-British terrorist movement was very strong in this upazila. The Congress activists used to make bombs at Ichapura and Madhyapara villages and distributed them to the workers of adjacent areas. While making bombs at village Madhyapara there occurred the incidental explosion of a bomb. At the intelligence of the explosion a military camp of the British Gorkha soldiers was set up at the junction of three roads on the western side of Ichapura-bazar, in order to suppress terrorist activities. The soldiers arrested a Congress activist named Abinash, persecuted and interrogated him with a view to detect information on the terrorist activities in the area, but in vain. During the war of liberation in 1971 one Abdul Aziz of village Shialdi was shot dead for uttering the slogan ‘Jai Bangla’ at the in front of the Pak-army. Abdul Aziz was the first martyr of the upazila in the war of liberation.
This area appears to have been named after one Sirajuddin Khan of village Rajdia on the south of the Ichamati. Sirajuddin Khan was fourth in decent from one Sujat Ali Khan who is said to have acquired a farman from the Mughal emperor Jahangir to check the raids of the Arakani pirates and settled at village Rajdia.
