Mercurino di Gattinara

When his sovereign became the Holy Roman Emperor as Charles V in 1519, Gattinara gained additional influence, but he never held the office of the Imperial Archchancellor (German: Reichserzkanzler), a honorary post traditionally reserved for the Archbishops of Mainz.

Gattinara would guide Charles away from both his roots in dynastic Burgundy, and from the prevailing secular political theory of Spain at the time, toward a Christian humanist conception of Empire.

In his capacity as Chancellor, he urged Charles V to create a dynastic empire with the object of establishing global rule ("Dominium Mundi").

Gattinara in his policy advice and personal writings argued for Christian imperialism, based on a united Christendom, which would then combat or convert the Protestants, the Turks, and the infidels of the New World.

Doubtless due in large part to Gattinara's counsel, the Habsburg Empire would reach its territorial height under Charles V, although it would begin to show signs of decay at the end of his reign, most importantly with the independence granted to the economically thriving but tax-averse Low Countries.

Gattinara's own summation of his views included the final goal of laying the foundations for a policy that was truly imperial, leading to a general war on the infidel and heretic.

Gattinara held Dante's dream of universal monarchy as the ultimate goal of Charles V's rule, united both Christendom and eventually the world.

Imperial ambassador at Henry VIII’s court, M. Louis de Praet, wrote to Charles: At this moment one may say that Your Majesty holds world monarchy in your hands, provided this victory over France is turned to good advantage.

If the English were to set foot in France, it would be a great advantage for Your Majesty, for it would weaken the enemy and prevent him from doing any further damage, and thus the surest means to a lasting peace.

Such favourable opportunity should not be lost.Charles’s secretary, Alfonso de Valdés, a humanist and Erasmian like Gattinara, would write to Charles after the victory of Pavia (a defeat for the French, including the capture of their king François I): It appears God has bestowed this victory on the Emperor in a wonderful manner so that he might defend Christendom and fight the Turks and Moors on their own ground so that the whole world receive our Holy Faith under this Christian Prince and the words of Our Savior be fulfilled: Fiet unum ovile et unus pastor.The Spanish missionary spirit is here wedded with Dante’s theocratic ideal and expresses the high expectations of the humanist Italians and Spaniards surrounding Charles.

The Emperor was seen as the reviver of the Roman universal Monarchy who could put an end to the feudal and dynastic conflicts, and establish a democratic imperium.

François would subsequently break the terms of the treaty, which had been to renounce claims in Italy, surrender Burgundy, and abandon suzerainty over Flanders and Artois.
