The Bengal Sultanate refers to an independent medieval Islamic state established in Bengal in 1342. Its realm and influence extended across modern-day Bangladesh, East India and West Burma. Several dynasties ruled over Bengal Sultanate sequentially. It disintegrated at the end of the 16th-century and was absorbed into the pan-South Asian Mughal Empire and the Arakanese Kingdom of Mrauk U.
Delhi lost its hold over Bengal in 1338, thus paving the way for the assumption of independence by Ilyas Khan." In 1342, a local warlord, Shamsuddin Ilyas Shah proclaimed himself as monarch of the Kingdom of Lakhnauti. He would go on to consolidate his rule by conquering the other independent kingdoms of Bengal before proclaiming himself as Sultan of Bengal.
