When Europe, spiritually united under the leadership of the Vatican, began to fracture along national lines, the focus shifted away from the Muslim enemy. The fourteenth and fifteenth centuries therefore saw a turn away from polemic toward indifference—until the Ottoman Empire began to advance into Europe in the early sixteenth century, heralding a new threat. This time, however, the enemy was seen as a secular and political threat rather than a religious one. The Ottomans were presented as Europeans of sorts and admired for their many accomplishments; European rulers forged alliances with them against other European rivals.

XREF: Connects to early modern European diplomatic history and the shift from crusading ideology to realpolitik in interstate relations.
