Holy League
Commencing in 1332 the numerous Holy Leagues were a new manifestation of the Crusading movement in the form of temporary alliances between interested Christian powers. Successful campaigns included the capture of Smyrna in 1344, at the Battle of Lepanto in 1571 and the recovery of the Balkans between 1684 and 1697. According to Arnaud Blin, "the Holy Leagues retained both the spirit and the language of the Crusades" while in practical terms being quite different. The initiative for a holy league often came from a secular power, not the pope, but papal involvement was inevitable if it was  to have the same spiritual benefits to participants as a crusade. Several factors encouraged the transition away from supranational crusades to state alliances, including the rise of the great powers in Europe and the unification of the Muslim enemy in the form of the Ottoman Empire.
