 Explanation– Partition of Bengal was division of Bengal carried out by the British viceroy in India, Lord Curzon. Bengal, Bihar, and Orissa had formed a single province of British India since 1765. By 1900 the province had grown too large to handle under a single administration. East Bengal, because of isolation and poor communications, had been neglected in favour of west Bengal and Bihar. Though, it was termed as an administration work but in reality it was a move by British to break the spirit of Nationalism in Bengal.

The arrival of King George V in 1911 in a royal durbar in Calcutta announced the reversal of partition move and also announced the transfer of capital of British India to the newly built city near Delhi.
