<Ul> <Li> </Li> <Li> </Li> <Li> </Li> </Ul> <P> The decision to effect the Partition of Bengal (Bengali: বঙ্গভঙ্গ) was announced on 19 July 1905 by the Viceroy of India, Lord Curzon . The partition took place on 16 October 1905 and separated the largely Muslim eastern areas from the largely Hindu western areas . The Hindus of West Bengal who dominated Bengal's business and rural life complained that the division would make them a minority in a province that would incorporate the province of Bihar and Orissa . Hindus were outraged at what they recognised as a "divide and rule" policy, where the colonisers turned the native population against itself in order to rule, even though Curzon stressed it would produce administrative efficiency . The partition animated the Muslims to form their own national organization on communal lines . In order to appease Bengali sentiment, Bengal was reunited by Lord Hardinge in 1911, in response to the Swadeshi movement's riots in protest against the policy and the growing belief among Hindus that east Bengal would have its own courts and policies . </P> <P> The provincial state of Bengal had an area of 490,000 km (189,000 mi) and a population of nearly 78.5 million . It comprised West Bengal with a Hindu majority and East Bengal and Assam with a Muslim majority . It included the Hindi - speaking regions of Bihar, the Odia - speaking regions of Odisha as well as the Assamese - speaking region of Assam, making it a huge administrative entity . Moreover, the capital, Calcutta, was also the capital of the entire British India . With the growing efforts of the Indian freedom fighters to secure the independence of India, Lord Curzon decided to address both these problems by partitioning Bengal into two entities, which would result in a Muslim - majority in the eastern part, and a Hindu - majority in the western part . This he hoped would reduce the administrative pressures . </P> <Table> <Tr> <Td> </Td> <Td> This section needs additional citations for verification .
