The new province was to be called ‘Eastern Bengal and Assam’ with its capital at Dhaka and subsidiary headquarters at Chittagong. It would cover an area of 106,540 sq. miles with a population of 31 million comprising of 18 million Muslims and 12 million Hindus. Its administration would consist of a. Legislative Council, a Board of Revenue of two members, and the jurisdiction of the Calcutta High Court would be left undisturbed. The government pointed out that the new province would have a clearly demarcated western boundary and well defined geographical, ethnological, linguistic and social characteristics. The most striking feature of the new province was that it would concentrate within its own bounds the hitherto ignored and neglected typical homogenous Muslim population of Bengal. Besides, the whole of the tea industry (except Darjeeling), and the greater portion of the jute growing area would be brought under a single administration. The government of India promulgated their final decision in a Resolution dated 19 July 1905 and the Partition of Bengal was affected on 16 October of the same year.
The publication of the original proposals towards the end of 1903 had aroused unprecedented opposition, especially among the influential educated middle-class Hindus. The creation of a Muslim majority province was resented by high caste Hindus, Hindu landlords, capitalists, traders, lawyers and particularly the Hindu press. The proposed territorial adjustment seemed to touch the existing interest groups and consequently led to staunch opposition. October 16, 1905 was declared as a day of mourning by Hindus. Unprecedented agitation was carried out by Hindus not only in Bengal but also in other parts of India. They alleged that by partitioning Bengal, the English had vivisected the Bengali homeland, divided Hindus and Muslims, and struck a deadly blow at Bengali nationalism, which would weaken nationalist and patriotic movements. The Hindus protested by coming out into the streets, walking barefoot and carrying ashes on their heads. They also started several agitational movements, such as the Charkha Movement, boycotting British goods and wearing local coarse cloth. The Swadeshi Movement was another boycott launched against the British. The Congress also supported the Hindu cause. The Calcutta lawyers apprehended that the creation of a new province would mean the establishment of a Court of Appeal at Dacca and diminish the importance of their own High Court. Journalists feared the appearance of local newspapers, which would restrict the circulation of the Calcutta Calcutta visualized the shift of trade from Calcutta to Chittagong, which would be nearer, and logically the cheaper port. The Zamindars who owned vast landed estates both in west and east Bengal foresaw the necessity of maintaining separate establishments at Dhaka that would involve extra expenditure. It is important to note that in 1901 when Punjab was divided into NWFP and Punjab, no such agitation was launched.
