Ibrahim Khan Fath-i-Jang alias Mirza Ibrahim Beg, Mughal governor of Bengal (1617-1624), son of Mirza Ghiyas Beg and brother of Empress Nur Jahan. He was a veteran of akbar's time and held various offices of trust and responsibility in the state including those of the Paymaster of the royal household (wakil-i-dar) and governor of Bihar. The new viceroy on his approach towards Dhaka faced vigorous obstruction from the dismissed viceroy qasim khan chisti who entered into bitter contest on the question of islam khan's escheat properties, but was ultimately worsted.

Ibrahim Khan's rule saw military exploits like the conquest of the kingdom of Tipperah (1618), suppression of rebellion in Kamraupa, successful repulse of the Magh raids (1620) and crushing of the Hijli revolt (1621) of bahadur khan. Throughout his tenure in Bengal, the province remained immune from external aggression of any serious nature.

In regard to internal administration Ibrahim Khan initiated a new policy of political conciliation and release of political prisoners. On his recommendation to the emperor the sons of Raja pratapaditya of Jessore, the Koch rajas Laksmi Narayan and Pariksit Narayan, were released and sent back to Bengal. The prominent zamindars, headed by musa khan who had been kept under surveillance at Jahangirnagar since the days of Islam Khan, were restored to liberty (1618). The effect of this political clemency was that the Koch rajas and the zamindars rendered valuable services to the Mughal government.

Peace and tranquillity mark the period of Ibrahim Khan's rule, lasting for about six years. He had honesty of purpose, a mastery of temper, a spirit of moderation, conciliation and compromise, and above all an innate nobility of character and dignity of bearing. All these endeared him to friends and foes alike. Agriculture and commerce were encouraged, and manufactures were carried to a degree of perfection. Dhaka muslin and Maldah silk attained the highest perfection in his time. During his rule the english first appeared in Bengal as wayside peddlers and had a small settlement somewhere in Piplay, close to Balassore. He began the construction of a fort at Dhaka (on the present central jail compound).

The peace and tranquility in Bengal under Ibrahim Khan was broken by the entry of the rebel Prince shahjahan (November 1623), who found safe asylum here after he was defeated and driven from Agra and the Deccan. Ibrahim Khan fell in an awkward situation, as it was a fight between the Emperor and his son. Ibrahim, of course, remained with the emperor till his death. He, however, failed to take effective steps to check the progress of the rebel prince in Bengal, who had entered Midnapur and Burdwan unopposed. Ibrahim's inaction gave Shahjahan the opportunity to enter Akbarnagar. Ibrahim at last prepared to face the rebel. The superiority of numbers of the rebel forces ensured their triumph. Ibrahim Khan fought the enemies with a handful of followers till he was slain (20 April 1624). He was laid to rest in a mausoleum at rajmahal. [Muazzam Hussain Khan]
