The Life of Castruccio Castracani of Lucca

Machiavelli asserts that men who have performed great deeds and excelled typically had humble or obscure beginnings, or were outraged by Fortune, suggesting Fortune deserves credit for their success.

Machiavelli introduces Castruccio Castracani as a man whose life demonstrates such significant virtue and fortune that he should serve as an exemplar to others.

Machiavelli narrates how Castruccio, born of unknown parents, was discovered as an infant and raised by Messer Antonio (a priest) and his sister Madonna Dianora.

Despite his foster father's intention to make him a priest, Castruccio showed exceptional wit and martial inclinations from an early age, abandoning religious study for arms and physical exercise.

A prominent Ghibelline gentleman, Messer Francesco, observes Castruccio's natural leadership among other boys and recruits him to become a soldier rather than a priest.

Under Francesco's tutelage, Castruccio rapidly develops into an accomplished horseman, skilled in martial exercises, while maintaining courtesy and modesty that make him beloved throughout Lucca.

Upon Francesco's death, Castruccio becomes tutor and administrator of Francesco's young son Pagolo, which increases his power but also generates envy from political rivals like Giorgio degli Opizi.

Castruccio forms a secret alliance with Uguccione of Pisa, communicates with exiled Ghibellines, and facilitates Uguccione's military entry into Lucca to drive out the Guelph leader Giorgio degli Opizi.

When Uguccione falls ill, Castruccio assumes command and defeats a much larger Florentine-Guelph army at Montecatini through superior tactical positioning, establishing his military reputation.

Castruccio's victory makes Uguccione jealous; he orders his son Neri to imprison and execute Castruccio, but this plan is thwarted when the people of Lucca demand his release.

After Uguccione's departure, Castruccio is appointed captain of Lucca's army, then deliberately made prince through manipulation of key supporters and popular election.

Castruccio rapidly captures numerous towns including Serezzana, Massa, Carrara, and Pontremoli, establishing control over Lunigiana and securing his authority over a growing territory.

Castruccio meets Frederick of Bavaria with five hundred horsemen and receives imperial recognition and appointment as Frederick's lieutenant in Tuscany, enhancing his legitimacy.

Various Ghibelline exiles from Tuscany seek Castruccio's assistance to recover their territories, and he forms a league with Matteo Visconti of Milan to pursue his ambitions in Tuscany.

The powerful Poggio family rebels against Castruccio's rule, but their uprising is quickly suppressed; Castruccio feigns clemency and then executes them after they surrender, demonstrating ruthless pragmatism.

After restoring order to Rome for Emperor Enrico by supplying grain and establishing authority, Castruccio is made a Roman senator, a dignity symbolized by a brocaded toga with divine inscriptions.

While Castruccio is in Rome, Pistoia rebels under Florentine influence; he returns and conquers the city by secretly meeting with rival faction leaders and having them murdered simultaneously.

Despite being outnumbered at Serravalle, Castruccio seizes the castle and uses superior tactics to route a much larger Florentine army, gaining near-total control of Tuscany.

Castruccio defeats a final massive Florentine army of over thirty thousand at the Arno crossing near Fucecchio, killing over twenty thousand enemy soldiers while losing only fifteen hundred men.

Despite his overwhelming military victory, Castruccio contracts a fatal fever from exposure to unhealthy winds at the Arno, dying at the moment when Fortune should have delivered Tuscany to him.

Dying, Castruccio counsels his successor Pagolo Guinigi to seek peace with Florence, secure his position through friendship rather than war, and recognize the limits of his own abilities.

After Castruccio's death, Pagolo Guinigi quickly loses Pisa, Pistoia, and nearly loses Lucca, lacking the abilities necessary to sustain the empire his predecessor had created.

Machiavelli describes Castruccio's exceptional stature, gracious presence, red hair, courage, prudence, and willingness to use fraud as well as force to achieve his ends.

Machiavelli provides numerous anecdotes of Castruccio's sharp, clever, and sometimes cruel wit in response to various courtiers and situations, illustrating his exceptional intelligence and confidence.

Machiavelli concludes that Castruccio lived forty-four years as a true prince, preserved instruments of his adversity, and matched or exceeded Philip of Macedon and Scipio in ability, dying at their same age.
