This chapter analyzes how Ottoman historians writing after a mature Mehmed IV moved to Edirne, depicting him as a model, active sultan. In their accounts he is a pious, strong, manly, warrior (ghazi) sultan, who reclaimed power taken by royal women and, with his preacher at his side, converted many people and many places throughout the Ottoman Europe. The perspective of contemporary chronicle writers allows a revision of how scholars have depicted Mehmed IV as well as the evolution of the sultanate and the figure of the sultan in the 17th century. According to the authors of books of kings and conquest books, works written to extol the virtues of the sultans and grand viziers who conquered infidel citadels and cities, sultans could still matter, and Mehmed IV certainly did. The chapter focuses on the link between conversion and conquest during the successful final siege of Candia, Crete.
