In 1564, Cosimo I delegated a substantial part of the government to his son Francesco. This led to an increase in

During this period, Serguidi carried out delicate diplomatic missions: in 1569, he was the extraordinary envoy of Cardinal Ferdinando to thank the pope for granting the grand ducal title.

. Serguidi was to inform Philip II that Grand Duke Francesco had shown a strong inclination to side with Spain and hoped to “deserve that His Majesty would finally declare his intention in this matter of the title and show that he warmly sheltered us under his wings”. Spanish recognition would arrive only on January 26, 1576. Serguidi was also tasked with asking Philip II to persuade the emperor “to desist from his obstinacy, as we have not proven ourselves useless or disloyal servants more than once”. In 1577, Serguidi once again journeyed to Spain, this time to pave the way for the visit of

Initially, Serguidi communicated with Antonio Pérez, Philip II's influential secretary, regarding matters of the Grand Duchy's foreign policy. Subsequently, he directly addressed Philip II, affirming that "all our faith – as Francesco wrote – is placed in him, and we will forever navigate by his north star." Furthermore, Serguidi had to defend Pietro, who was accused of killing his wife, Eleonora, a member of the prominent

Justifying Pietro's actions by citing his wife's public adultery served as the basis for requesting a position for Pietro at the Spanish court and a place for him in the military. Serguidi also sought the appointment of Cardinal Ferdinando as protector of Spain. He presented a prestigious gift: a marble crucifix by

Under Francesco

Upon Cosimo I's death in 1574, Francesco assumed full control of the Grand Duchy, but his inclination was to delegate its management to others. Initially, Bartolomeo Concini held a prominent role, but after 1576, possibly due to his advanced age, the handling of important matters shifted to his son-in-law, Serguidi. However, following Joanna of Austria's death in 1578 and Francesco's subsequent marriage to

, the Grand Duke fell under the sway of those close to his new wife, notably her brother Vittorio, who was perceived by many to have a negative influence on Francesco. Cardinal Ferdinando, observing from Rome, grew concerned about this development and intervened to remove some of these figures from the court. He favored Serguidi taking charge of government affairs, believing it "less damaging to his brother's dignity for Serguidi to take the lead in matters." As a result, Serguidi "remained in charge of the main direction of the government and cabinet." In line with the evolution of the government structure, he was appointed first secretary in 1579, succeeding his father-in-law. Within a few years, he consolidated all power in his hands, overseeing "state affairs and negotiations with princes, ambassadors, and other important matters." The date of his first wife's death remains unknown, but after his father-in-law's demise in 1578, he married Orinzia Carpegna later that same year.


Under Ferdinando

Following the death of Francesco in 1587, Serguidi's political standing diminished. The new Grand Duke, Ferdinando I, aimed to curtail the political influence of Francesco's favored ministers, particularly Serguidi. In November 1587, Ferdinando established a three-member secretariat, including Serguidi alongside
