Francis I: The Knight King and the French Renaissance (1515–1547) · RENAISSANCE

The rivalry between Francis I and Charles V dominated European politics throughout Francis I’s reign, marked by the imperial election of 1519, which sealed the rivalry between the two sovereigns.

👑 Francis I’s Imperial Ambitions

The death of Emperor Maximilian I, on 12 January 1519, opened a succession that went far beyond German affairs alone: candidates for the vacant throne of the Holy Roman Empire included Charles I of Spain — the future Charles V —, Francis I, and, more symbolically, Henry VIII of England as well as George of Saxony, put forward as a compromise candidate. For Francis I, the stakes went beyond mere prestige: winning the imperial crown would at once crown his Italian policy, durably counterbalance the rising power of the Habsburgs, and satisfy a personal ambition for glory further fanned by the memory of Marignano.

🏛️ The Electoral Process

Seven prince-electors decided the fate of the imperial throne: three churchmen — the archbishops of Mainz, Cologne and Trier — and four laymen — the King of Bohemia, the Count Palatine of the Rhine, the Duke of Saxony and the Margrave of Brandenburg. Francis I deployed active diplomacy, multiplying ambassadors, promises of pensions and arguments on the need to preserve the European balance against Habsburg power. But Charles V held decisive advantages: the financial backing of the Fuggers, bankers of Augsburg, his status as grandson of Maximilian I himself, and the considerable resources of an empire on which, as would later be said, “the sun never sets.”

💰 The War of Bribes

The election campaign quickly turned into a financial bidding war. Francis I, whose initial budget of three hundred thousand florins climbed to five hundred thousand, multiplied promised annual pensions, lands, titles and gifts — jewels, works of art, trading privileges. Charles V, backed by the Fugger bank and by the gold of the Americas, systematically outbid him: to the Archbishop of Mainz, one hundred thousand florins from each side, but Charles added ten thousand florins a year; to the Archbishop of Cologne, fifty thousand florins from Francis I against sixty thousand from Charles; to the Elector of Saxony, seventy thousand French florins against one hundred thousand florins and territorial promises from the imperial side. Elector after elector, the Habsburg bid won out.

🏆 The Election of Charles V

The vote took place in Frankfurt am Main, by secret ballot, on 28 June 1519: Charles V was elected unanimously. Several factors explain this French defeat — the Fuggers’ financial superiority, Charles’s dynastic inheritance, his family networks in Germany, his more generous territorial promises, and a diffuse German mistrust of French power. For Francis I, the failure translated into a loss of international prestige and colossal spending with no result whatsoever; for Charles V, it was followed, on 23 October 1520, by a coronation held with great pomp at Aachen, adding the imperial title to his already long list of crowns.

🤝 The Field of the Cloth of Gold (1520)

Seeking to make up for this failure, Francis I organised with Henry VIII, from 7 to 24 June 1520, between Ardres and Guînes, a meeting of unheard-of splendour — tents of silk and velvet, fountains flowing with wine, sumptuous banquets, tournaments, exchanges of gifts and oaths of eternal friendship. But this very excess of display ended up working against its purpose: Henry VIII’s mistrust, skilfully nurtured by Cardinal Wolsey, and Francis I’s lack of diplomatic subtlety condemned the meeting to failure, paving the way for the Treaty of Bruges of 1521, which instead sealed an alliance between England and Spain — isolating France a little further on the European chessboard.

⚔️ The Consequences of the Rivalry

From this election a structural rivalry was born: on one side, a Charles V who had become master of the Holy Roman Empire, Spain, Naples, Sicily and the Netherlands; on the other, a Francis I whose Italian claims to Naples and Milan now ran up against an adversary of an altogether different stature. This rivalry led, as early as 1521, to the first of the wars that would punctuate the whole reign — Bicocca in 1522, the Sesia in 1524, and above all Pavia in 1525, where Francis I himself was captured, a prelude to the Treaty of Madrid of 1526 and the loss of the Italian conquests. The whole of Europe found itself rebalanced in the Habsburgs’ favour, France feeling itself gradually encircled — a situation that pushed Francis I to redirect his diplomacy towards more unexpected alliances, with the German Protestant princes and with the Ottoman Empire of Suleiman the Magnificent.

👑 The Personal Relations Between Francis I and Charles V

It would nevertheless be misleading to reduce this relationship to pure hostility: despite the fierce rivalry that set them against each other, the two sovereigns showed one another, in public, all the respect that protocol demanded. Francis I thus received Charles V on several occasions — notably at the Louvre, just before the works of its reconstruction began. In 1540, it was at Charles V’s own request, eager to cross France in order to put down a revolt in Flanders, that one of the most astonishing episodes of this relationship unfolded: setting out from Bordeaux, the emperor crossed Poitiers on 8 December 1539, then Orléans, before being welcomed and personally accompanied by Francis I on his entry into Paris. The King of France went so far in courtesy as to show him the just-completed gallery at Fontainebleau — a way, too, of impressing his rival with the brilliance of his patronage, Renaissance diplomacy readily turning into spectacle and staging.

The two sovereigns also tried, on several occasions, to seal their rivalry through family ties: Francis I for a time offered the hand of his daughter Louise to Charles V — a project that came to nothing, the little princess dying in infancy — and it was ultimately Charles V who arranged, in 1530, the marriage of his own sister Eleanor to Francis I, in the hope of establishing a lasting climate of peace between the two crowns. But these marriage alliances, no more than the most courteous protocol visits, were enough to extinguish the underlying rivalry between the two men: the courtesy of appearances coexisted, without ever truly replacing it, with a political and territorial competition that would cease only with the death of Francis I. This very particular combination of splendour, courtesy and simmering confrontation says a great deal about what princely diplomacy was in the Renaissance — an art in which appearances counted for almost as much as the balance of power itself.
