The determined attempt to thwart Ottoman dominance was fought by Muslims and Christians across five theaters from the Balkans to the Mediterranean and the Indian Ocean, from Persia to Russia.

But this is not merely the story of a clash of civilizations between East and West. Europe was not united against the Turks; the scandal of the age was the alliance between King Francis I of France and Sultan Suleiman the Magnificent. Meanwhile, the resistance of the Saadi dynasty of Morocco to Ottoman encroachment played a critical role in denying Constantinople direct access to the Atlantic Ocean. By the same token, though religious imperatives were critic al to the motivations of all the key actors involved, these in no way fell neatly along the Christian Muslim divide.

The Holy Roman Emperor Charles V desired nothing more than to eradicate the Protestant heresy metastasizing throughout his domains, but the threat of Turkish invasion forced him to stay his hand and indulge his Lutheran subjects to ensure a common defense. Nevertheless, the collective effort to constrain the expansion of the Ottoman superpower did succeed with the ultimate victory in 1571 the tipping point in reordering the trajectory of history.

To explore these facets of medieval and early modern European history is today’s guest, Si Sheppard, author of “Crescent Dawn: The Rise of the Ottoman Empire and the Making of the Modern Age.”
