Bengal Sultan
The Bengal Sultanate was a sovereign state that encompassed present-day Bangladesh, the Indian state of West Bengal and the Myanmarese state of Rakhine between the 14th and 16th centuries.
Bengal was gradually absorbed into the Delhi Sultanate during the 1200s. It began with Bakhtiar Khilji’s conquest of Gauda between 1202 and 1204 during the reign of Muhammad of Ghor. After the assassination of Bakhtiar Khalji by his own officer Ali Mardan in 1206, Bengal was administered by various Maliks belonging to the Khalji tribe (except a brief interregnum by Ali Mardan himself) till Delhi Sultan Iltutmish sent forces under his son, Nasir-ud-din Mahmud, to bring Bengal under the direct control of the Delhi Sultans
The Bengal Sultanate arose after the reign of Muhammad Bin Tughlaq of the Tughlaq Dynasty.
