The internet has many flags attributed to the Bengal Sultanate and many aren’t real. This however actually is a real banner used by Alauddin Hussain Shah during his military expedition in Tripura. While the campaign was successful he faced initial setbacks in which the King of Tripura, Dhanya Manikya was able to capture the Sultans banner (Alam). This is the first flag or banner or standard of the Bengal Sultanate that I have seen which has both primary and secondary corroboration.
