<P> Partition sparked an extremely major political crisis along religious lines . Hindu resistance exploded as the Indian National Congress began the Swadeshi movement that included boycotting British goods and public institutions, meetings and processions, forming committees, propaganda through press, and diplomatic pressure . Hitherto untouched sections of Indian society participated in these movements, providing base for later movements . Richness of the movement extended to culture, science and literature . Masses were educated for a bolder form of politics and colonial hegemony was undermined . The Muslims in East Bengal hoped that a separate region would give them more control over education and employment, hence, they opposed those movements . Rabindranath Tagore wrote Banglar Mati Banglar Jol as a rallying cry for proponents of annulment of Partition . </P> <P> Opposition to the partition was supported by Sir Henry John Stedman Cotton who had been Chief Commissioner of Assam, but Curzon was not to be moved . Later, Cotton, now Liberal MP for Nottingham East coordinated the successful campaign to oust the first lieutenant - governor of East Bengal, Sir Bampfylde Fuller . </P> <P> Due to these political protests, the two parts of Bengal were reunited on 12 December 1911 . A new partition which divided the province on linguistic, rather than religious grounds followed, with the Hindi, Oriya and Assamese areas separated to form separate administrative units: Bihar and Orissa Province was created to the west, and Assam Province to the east . The administrative capital of British India was moved from Calcutta to New Delhi as well . </P> <P> In 1909, separate elections were established for Muslims and Hindus . Before this, many members of both communities had advocated national solidarity of all Bengalis . With separate electorates, distinctive political communities developed, with their own political agendas . Muslims, too, dominated the Legislature, due to their overall numerical strength of roughly twenty two to twenty eight million . Nationally, Hindus and Muslims began to demand the creation of two independent states, one to be formed in majority Hindu and one in majority Muslim areas . </P>
