Ghiyasuddin Bahadur Shah
Ghiyasuddin Bahadur Shah I was the son and successor of Sultan Shamsuddin Firoz Shah of the Bengali kingdom of Lakhnauti. Ghiyasuddin Bahadur Shah issued coins when his father was still living. On the death of his father he ascended the throne in 1322 and ruled up to 1324. Ghiyasuddin Tughlaq, sultan of Delhi, declared war upon him in 1324, captured him and took him to Delhi as a prisoner. Bengal was thus turned into a province of the Delhi Sultnate. Sultan Muhammad bin Tughlaq (son and successor of Ghiyasuddin Tughlaq) released him and gave him the assignment to rule Sonargaon as a vassal. He, however, asserted independence in 1328 and therefore was defeated and killed by the imperial general of the sultan of Delhi, Bahram Khan. Bahram Khan recaptured Sonargaon for the Delhi Sultanate and became the governor of Sonargaon. Ghiyasuddin Bahadur Shah founded a new city, ghiyaspur, at a site 24 Kilometre southwest of Mymensingh.[1]
