Shamsuddin Muzaffar Shah (reigned 1490–94) was a sultan of the Bengal Sultanate. Sidi Badr first killed Habash Khan, the regent of the boy-king Mahmud Shah II, and later killed the sultan also.
He ascended the throne under the title of Shams-ud-Din Muzaffar Shah. He is described by the Indo-Persian historians as a tyrant, whose cruelty alienated the nobles as well as his common subjects.[1] He was killed in 1494 by the rebels led by his wazir Sayyid Husain, who succeeded him as Alauddin Husain Shah.
