The history of Bangladesh is related to that of the larger area of Bengal, which became independent of Delhi by 1341. After a succession of Muslim rulers, it was conquered by Akbar, the great Mughal emperor in 1576. By the beginning of the 18th cent., the governor of the province was virtually independent, but he lost control to the British East India Company, which after 1775 was the effective ruler of the vast area, which also included the Indian states of West Bengal, Orissa, Jharkhand, and Bihar.

Bengal was divided by the British in 1905 into West Bengal and East Bengal, with East Bengal being more or less coterminous with modern Bangladesh. Since the new province had a majority Muslim population, the partition was welcomed by Muslims, but it was fiercely resented by Indian nationalist leaders who saw it as an attempt to drive a wedge between Muslims and Hindus. The partition was withdrawn in 1911, but it had pointed the way to the events of 1947, when British India was partitioned into the states of India and Pakistan.
