The Battle of Rajmahal (Bengali: রাজমহলের যুদ্ধ) took place between the Mughal Empire and the Karrani Dynasty that ruled the Sultanate of Bengal in the 16th century.

During the battle, the last Sultan of Bengal, Daud Khan Karrani, was captured and later executed by the Mughals.

Despite occupying the capital city of Gaur, Humayun, the second emperor of the Mughal Empire, was able to hold the control for only a short period of time.

The founder of the Sur Dynasty, Sher Shah Suri defeated Humayun in the Battle of Chausa and took control over Bengal.

[4] Akbar sent his general Khan-i-Jahan Husain Quli Beg to conquer Bengal from Daud Khan.

As an additional aid to the Mughals, Muzaffar Khan Turbati, the ruler of Bihar, came forward with five thousand cavalry and supplies by sea.
