After the Muslim conquests in the Indian subcontinent, Bengal was ruled by Muhammad bin Bakhtiyar Khalji, under whom Indian Islamic missionaries achieved their greatest success in terms of dawah and number of converts to Islam, which caused the decline of Buddhism. The Islamic Mamluk Sultanate, the Khalji dynasty, the Turko-Indian Tughlaq dynasty, the Sayyid dynasty and the Lodi dynasty ruled Bengal for over 320 years. Notable was Malik Altunia's reign with his wife Razia Sultana, the only female sovereign ruler.
