At the time of partition Bengal was the biggest province of British India which comprised Bihar and parts of Orissa. The British argued for dividing Bengal for reasons of administrative convenience. But it was a totally false argument. In fact, the partition of Bengal was closely tied to the interests of British officials and businessmen. The British also wanted to curtail the influence of Bengali politicians and split the Bengali people. It was therefore, instead of removing the non-Bengali areas from the province, they separated East Bengal and merged it with Assam.
