Rajmahal the capital of Bengal in 1592. But this honour of Rajmahal was short-lived, for the capital was shifted to Dhaka in 1608. Shortly after this, Teliagarhi and Rajmahal became the site of a fierce battle between the rebellious Prince Shahjahan and Ibrahim Khan. Shahjahan emerged victorious and became the overlord of Bengal for a time, before finally being defeated in 1624 at Allahabad. In 1639, Rajmahal regained its glory and was once more made the capital of Bengal by Shah Shuja, the second son of Emperor Shahjahan, on his appointment as the Viceroy of Bengal. It continued as the seat of the Mughal Viceroy up to 1660 and a mint town till 1661. It was at Rajmahal that Dr. Gabriel Boughten cured the daughter of Shah Shuja. By this means Dr. Boughten succeeded in securing an order (farman) from Shah Shuja giving the English the liberty to trade in Bengal. Thus the minutest foundation of the British rule was laid here. The fugitive Nawab of Bengal Siraj-ud- Daula was captured at Rajmahal during his flight after the Battle of Plassey in 1757. Modern Period The entire Santhal Pargana along with portions of the present Hazaribagh, Munger, Jamui, Lakhisarai, Begusarai, Saharsa, a part of Purnia and Bhagalpur, districts was termed as "Jungle Terai" by the English on assumption of Diwani in Sept. 1763 from Shah Alam II at Allahabad after the Allahabad Treaty. The victory at Plassey made British master of the then Bengal which contained the present Sahibganj District. In Santhal Pargana, they were up against a band of simple but determined opponents, the Paharias. Paharias were lovers of freedom and could not tolerate any intruder in their homeland. The English were very much concerned and Warren Hastings the Governor General of India organized a special corps of 800 men in 1772 to curb the Paharias. The corps was put under the command of Captain Brooke, who was appointed the Military Governor of the Jungle terai. As a direct consequence of the Santhal Hul or Rebellion of 1854–55 led by Sido and Kanu brothers Santhal Pargana has been created as a separate district in 1855 by ceding portions of Bhagalpur (which is now in Bihar) and Birbhum (which is now in West Bengal) district. The 1942 movement also spread to entire Santhal Pargana division, for that matter in Sahibganj and on 11 August 1942 a general strike was observed.
