Sonargaon

Sonargaon was a river port on the old Brahmaputra in eastern Bengal. In 1337 Bahram Khan held it as governor for Delhi.

After Bahram died in 1338, his armour-bearer Fakhruddin Mubarak Shah declared himself independent sultan and conquered Chittagong in 1340; Ibn Battuta visited his court. Sonargaon later became a Bengal Sultanate capital. Isa Khan led the Baro-Bhuyan landlords against the Mughals from the town, until his son Musa Khan’s defeat in 1610 made it a Mughal district overshadowed by Dhaka.
