Shah

The Shah house of Sonargaon was the Mubarak Shahi dynasty, founded by Fakhruddin Mubarak Shah, a Bengali Muslim from Noakhali who served Bahram Khan, the Delhi governor of Sonargaon. When Bahram Khan died in 1337, Fakhruddin seized the city and declared himself an independent sultan.

He defeated and executed Qadar Khan, governor of Lakhnauti, and took Comilla, Noakhali and Sylhet. In 1340 he became the first Muslim ruler to conquer Chittagong, Bengal's chief port. Ibn Battuta visited Sonargaon in 1346 and praised him for welcoming strangers and Sufis.

Fakhruddin died in 1349 and was succeeded by Ikhtiyaruddin Ghazi Shah, probably his son, who ruled until 1352. Shamsuddin Ilyas Shah then conquered Sonargaon and united Bengal under the Bengal Sultanate.
