199 – The dying gasp of the Fiorentine Republic and the first duke

Episode Summary

With Giovanni dalle Bande Nere gone, we return to Florence to witness the dramatic collapse of the centuries-old Florentine Republic and the emergence of Medici princely rule. Against the backdrop of the Sack of Rome, religious extremism, political infighting, and imperial intervention, this episode follows Florence’s final republican experiment and introduces one of its most controversial rulers: Alessandro de’ Medici, the first Duke of Florence.

Key Topics Covered

The Aftermath of the Sack of Rome (1527)

1. Pope Clement VII’s humiliation after the Sack of Rome by mutinous imperial landsknechts and the blow to Medici prestige.
2. The pope’s political failures, including his looming clash with Henry VIII and the broader collapse of Medici papal authority.
3. Florence’s growing disillusionment with Medici “informal rule” and the sense that the moment for change had arrived.

The Republican Revival in Florence

1. Early unrest during the passage of imperial troops and the damage to Michelangelo’s David.
2. The fall of Cardinal Silvio Passerini’s authority after the Sack of Rome.
3. The decisive confrontation involving Clarice de’ Medici and Filippo Strozzi that triggered the Medici flight from the city.
4. The rise of a new republican government under Gonfalonier Niccolò Capponi.
5. Factional divisions among the anti-Medici forces, from aristocratic moderates to radical, Savonarola-inspired religious extremists.
6. The extraordinary moment when Jesus Christ was proclaimed King of Florence in February 1529.

Siege, Resistance, and the End of the Republic

1. The Treaty of Barcelona (1529) between Clement VII and Charles V, sealing Florence’s fate.
2. The imperial siege of Florence and Michelangelo’s role—brief and reluctant—in strengthening the city’s defenses.
3. Internal betrayal and wavering leadership under Malatesta Baglioni.
4. Florentine defiance through ritual and sport: frozen-Arno games, Carnival football in Santa Croce, and cannon fire aimed at celebration.
5. Capitulation in August 1530 after famine and plague, and Clement VII’s intervention to prevent a sack.
6. The definitive death of the Florentine Republic.

The Rise of Alessandro de’ Medici

1. Alessandro’s appointment as Gonfalonier for life and later Duke of Florence, with authority imposed by imperial decree rather than civic choice.
2. Competing theories about his parentage and his nickname il Moro.
3. The transformation of Florence from republic to hereditary state.
4. Abolition of traditional republican institutions and creation of new councils loyal to ducal authority.

What Kind of Duke Was Alessandro?

1. His populist instincts and rapport with the lower classes, including public sports and personal modesty.
2. A strong commitment to justice, legal transparency, and accessible law codes.
3. Absolute rejection of republican freedom and ruthless suppression of dissent.
4. Confiscation of noble estates, exile extensions, and political repression to rebuild state finances.
5. His indulgent private life: hunting, luxury, perfumes, and a notorious sexual appetite that fueled opposition.

Opposition, Intrigue, and Assassination

1. The death of Pope Clement VII in 1534 and the loss of Alessandro’s greatest protector.
2. The emergence of Ippolito de’ Medici as an alternative claimant and his suspicious death in 1535.
3. Failed legal attempts to remove Alessandro, including a trial in Naples.
4. The betrayal by Lorenzino de’ Medici—friend, companion, and assassin.
5. The murder of Alessandro on the night of 6 January 1537 and the desperate secrecy surrounding his death.
6. The political vacuum left behind and the difficulty of founding a dynasty when its first duke dies so quickly.

Why This Episode Matters

This chapter marks a decisive turning point in Florentine—and Italian—history:

1. The final collapse of republican government in Florence.
2. The normalization of foreign domination in Italian politics.
3. The emergence of Medici rule not as behind-the-scenes power brokers, but as open, hereditary princes.

The question now is no longer whether Florence will be ruled by a Medici—but which Medici will rule it next.
