Partitioning Bengal was first considered in 1903. There were also additional proposals to separate Chittagong and the districts of Dhaka and Mymensingh from Bengal and attaching them to the province of Assam. Similarly incorporating Chhota Nagpur with the central provinces.
The government officially published the idea in January 1904, and in February, Lord Curzon made an official tour to eastern districts of Bengal to assess public opinion on the partition. He consulted with leading personalities and delivered speeches at Dhaka, Chittagong and Mymensingh explaining the government's stand on partition.
The new province would consist of the state of Hill Tripura, the Divisions of Chittagong, Dhaka and Rajshahi (excluding Darjeeling) and the district of Malda incorporated with Assam province. Bengal was to surrender not only these large eastern territories but also to cede to the Central Provinces the five Hindi-speaking states. On the western side it was offered Sambalpur and five minor Oriya-speaking states from the Central Provinces. Bengal would be left with an area of 141,580 sq. miles and population of 54 million, of which 42 million would be Hindus and 9 million Muslims.
The new province was named Eastern Bengal and Assam with Dhaka as its capital and subsidiary headquarters at Chittagong. Its area would be 106,540 sq. miles with a population of 31 million, where 18 million would be Muslims and 12 million Hindus. 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 Eastern Bengal and Assam would have a clearly demarcated western boundary and well defined geographical, ethnological, linguistic and social characteristics. The government of India promulgated their final decision in a resolution dated July 19, 1905 and the partition of Bengal was effected on October 16 of same year....
