Fermo is presented as the city that Oliverotto da Fermo set out to capture when he decided that serving under others was beneath him. His seizure of the city turns Fermo into a concentrated study of political usurpation: a return staged as a family celebration becomes a trap, the killing of the city’s leading men becomes the opening for a new regime, and military and civil ordinances transform terror into a temporary structure of rule. Fermo’s political significance lies not only in the violence of its conquest but in the speed with which violence is converted into obedience and local government.

Setting and Political Condition

Fermo appears as Oliverotto’s native city and the patrimony whose condition he wished to inspect after years of absence. He had been orphaned some years earlier and raised by his maternal uncle, Giovanni Fogliani. That familial connection gives the city’s political drama an intimate foundation: Fermo is not an anonymous territory encountered from outside, but the place to which Oliverotto can return with the authority of a native son and the emotional legitimacy of a nephew.

The seizure also depends on a division within Fermo itself. Certain citizens, preferring slavery to the freedom of their country, connived at Oliverotto’s design. The city therefore contains the political constituency that makes conquest possible from within. Its fall is not described as the result of an external army alone; it is enabled by civic collaborators who choose a new master over the preservation of their country’s freedom.

Oliverotto’s Return and the Coup

Oliverotto carefully fashioned his return as a public display of honor. He wrote to Giovanni Fogliani that, after many years away, he wished to see his home and native city again and examine his patrimony. He proposed to arrive with one hundred horsemen drawn from his friends and followers, asking his uncle to arrange a reception marked by corresponding distinction. The request was framed as a tribute to his own hard-won reputation and to the uncle who had raised him, but it concealed the practical requirements of a coup: armed men, public access, and the confidence of the city’s leading household.

Giovanni responded with every appropriate courtesy. He arranged a splendid reception by the citizens of Fermo and lodged Oliverotto in his own house. Oliverotto then spent several days making the arrangements necessary to carry out his plan. The hospitality of the city and the protection of the family home thus became instruments of its overthrow; the trust extended to a returning relative supplied the cover under which the armed force could be positioned.

He next gave a formal banquet for Giovanni and all the leading men of Fermo. After the meal and the other entertainments had ended, Oliverotto directed the conversation toward the power of Pope Alexander VI and Cesare Borgia and their enterprises. He then suggested that such serious matters should be discussed in a more private place and led the company into another chamber. Once Giovanni and the other citizens had followed and seated themselves, soldiers emerged from concealment and killed them all. The coup’s decisive gesture is therefore a change of room: public sociability gives way to enclosed violence, and family intimacy becomes the mechanism of mass assassination.

Consolidation Through Fear and Ordinance

After the slaughter, Oliverotto mounted his horse, rode through the streets, and besieged the chief magistrate in the palace. The movement from the banquet chamber to the streets and then to the seat of civic authority shows how quickly the seizure expanded from a hidden murder to an open claim on the city. Those inside the palace were compelled by fear to obey and accept a government headed by Oliverotto.

He killed those whose disaffection made them likely obstacles and strengthened himself through new civil and military ordinances. These measures gave the violence of the coup a continuing institutional form. For the year during which he retained the princedom, Oliverotto held Fermo firmly and became formidable to all his neighbors. The city therefore illustrates a distinction between taking power and maintaining it: assassination opened the way, but ordinances, coercive selection of opponents, and control of both civil and military arrangements made the seizure durable enough to appear politically established.

Fermo’s population is not described through a collective decision or a freely expressed allegiance. Its obedience is produced under the pressure of fear after the magistrate is besieged and potential opponents are removed. The city becomes governable because its visible centers of resistance have been destroyed or intimidated, not because Oliverotto has secured legitimacy independent of force.

Overthrow and Political Significance

Oliverotto’s rule ended when he was outmaneuvered by Cesare Borgia during the entrapment of the Orsini and Vitelli at Sinigaglia. Although Fermo had been held for a year and Oliverotto had grown powerful enough to threaten neighboring rulers, his position ultimately depended on a political environment larger than the city itself. He was captured and, one year after the parricidal crime committed at his banquet, strangled together with Vitellozzo Vitelli, whom he had taken as his master in both villainy and valor.

Fermo thus becomes an example of power that is locally consolidated but strategically exposed. Oliverotto could seize the city through personal reputation, armed followers, civic connivance, treachery, and fear; he could reinforce that seizure through civil and military ordinances; yet he could not prevent a superior political actor from turning the same networks of military association and conspiracy against him. The city’s episode gives concrete form to the broader contrast between political capacity and moral glory. Oliverotto’s daring and administrative effectiveness help explain how he ruled Fermo, while the murders that enabled his rule remain crimes rather than merits.

The city also clarifies the difference between spectacular cruelty and lasting security. Fermo’s transformation is rapid: a welcoming reception, a banquet, a concealed attack, a besieged magistrate, and a new government follow one another in a compressed sequence. But the ending reveals that internal command over one city cannot by itself secure a prince against external calculation. Fermo is held firmly, yet its ruler is not secure; the city’s apparent stability lasts only until a stronger power changes the political conditions around it.
