Ottoman embassy to France (1534)

[2] At that time, Francis I was confronted with the Affair of the Placards, in which Protestants issued pamphlets criticizing the Mass in view of stopping efforts at a Catholic–Protestant rapprochement.

[3] Jean de la Forest would successfully negotiate the Capitulations giving advantages and pre-eminence to France in relations with the Ottoman Empire.

[4] De la Forest also had secret instructions describing how he was to coordinate the military efforts between France and the Ottoman Empire:[4] "Jean de la Forest, whom the King sends to meet with the Grand Signor [Suleiman the Magnificent], will first go from Marseilles to Tunis, in Barbary, to meet sir Haradin, king of Algiers, who will direct him to the Grand Signor.

To this objective, next summer, he [the King of France] will send the military force he is preparing to recover what it unjustly occupied by the Duke of Savoy, and from there, to attack the Genoese.

[4] Charles V managed to wreck the plans of Francis I by launching a major attack on the Ottomans with the Conquest of Tunis in June 1535, immediately after the departure of the embassy.
