Fakhruddin Mubarak Shah
Fakhruddin Mubarak Shah (r. 1338–1349) was the founder of the independent sultanate of Sonargaon. A Bengali Muslim who rose as armour-bearer to the Delhi governor Bahram Khan, he seized power after Bahram died in 1337 and made Sonargaon his capital. After Qadar Khan of Lakhnauti occupied the city, Fakhruddin lured his troops amid a dispute over the spoils, killed Qadar Khan and recovered Sonargaon.
He then conquered Comilla, Noakhali and Sylhet, and in 1340 became the first Muslim ruler to take Chittagong. He died in 1349 and was succeeded by Ikhtiyaruddin Ghazi Shah.
