Mughal Empire annexes Bengal after defeating the Bengal Sultanate at the Battle of Rajmahal.

The Mughal Empire was an early modern empire in South Asia. At its peak, the empire stretched from the outer fringes of the Indus River Basin in the west, northern Afghanistan in the northwest, and Kashmir in the north, to the highlands of present-day Assam and Bangladesh in the east, and the uplands of the Deccan Plateau in South India.

Bengal is a historical geographical, ethnolinguistic and cultural term referring to a region in the eastern part of the Indian subcontinent at the apex of the Bay of Bengal. The region of Bengal proper is divided between the modern-day sovereign nation of Bangladesh and the Indian states of West Bengal, and Karimganj district of Assam.

The Bengal Sultanate was a late medieval sultanate based in the Bengal region in the eastern South Asia between the 14th and 16th century. It was the dominant power of the Ganges-Brahmaputra Delta, with a network of mint towns spread across the region. The Bengal Sultanate had a circle of vassal states in the Indian subcontinent, including parts of Odisha in the southwest, parts of Bihar in the northwest, parts of Assam in the northeast, Arakan in the southeast, and Tripura in the east.

The Battle of Rajmahal took place between the Mughal Empire and the Karrani Dynasty that ruled the Sultanate of Bengal in the 16th century. The battle resulted in a decisive victory for the Mughals. During the battle, the last Sultan of Bengal, Daud Khan Karrani, was captured and later executed by the Mughals.
