In this episode, we pick up with Emperor Charles V consolidating his power over Italy after the Battle of Pavia (1525), where the French king Francis I was captured. The uneasy Italian states, including Pope Clement VII (Giulio de’ Medici), soon realized they had traded one master for another and formed the League of Cognac (1526) — an anti-imperial alliance including France, Venice, Florence, the Papal States, Milan, and under English protection, Henry VIII.

The league’s formation was steeped in intrigue, false pretenses, and even secret dealings with the Turks. One of Charles’s own commanders, the Marquis of Pescara, pretended to side with the league while feeding the emperor inside information.

Meanwhile, Giovanni dalle Bande Nere, the famed mercenary from the Medici-Sforza line, met his end in battle, struck by artillery supplied by the duplicitous Duke of Ferrara. His death marked the fading of Italy’s old mercenary tradition — and one of its most charismatic figures.

When the pope attempted to back away from the alliance, Charles’s allies struck at Rome. The Sack of Rome (1527)followed — a devastating episode where mutinous Landsknechts, many of them fervent Lutherans, unleashed horrific violence on the city. For days, the Eternal City was ravaged: thousands slaughtered, churches desecrated, art looted, and the Renaissance dream in Rome brutally extinguished. Pope Clement VII barely escaped to Castel Sant’Angelo, thanks to the sacrifice of his Swiss Guards.

In the chaos that followed, the Papal States collapsed, local lords reclaimed their territories, and the Medici were expelled from Florence, where a new republic was declared — with Jesus Christ symbolically named as its king.

Ultimately, Charles V and Clement VII reconciled. Political realism won out over ideology. Through the Treaties of Barcelona (1529) and Bologna (1530), the Italian Wars entered a quieter phase, and imperial dominance over Italy was secured.

We close with the final chapter of the Sforza dynasty: Francesco II Sforza, the last Duke of Milan, whose death in 1535marked the end of an era — from the rise of the free communes to the age of dynastic rule and foreign domination.
