Shamsuddīn Aḥmad Shāh (Bengali: শামসউদ্দীন আহমদ শাহ, Persian: شمس الدین احمد شاه; r. 1433–1436) was the last Sultan of Bengal belonging to the House of Ganesha.
[6] His father had good ties with Barsbay,[7] a Mamluk sultan who had gifted Jalaluddin with investiture, a robe of honour and a letter of recognition.
After Barsbay was informed of this by the Governor, he ordered for the arrest of all members of the Bengali embassy, the confiscation of their envoy's merchandise, and banned them from ever travelling to Cairo again.
[12] Contemporary historian Firishta mentions that one of Ahmad Shah's attendants, "Nasir ad-Din Ghulam", seized the throne after his death.
The nobles subsequently installed to the throne a farmer named Mahmud, after realising that he descended from the Ilyas Shahis, the inaugural ruling dynasty of Bengal.
