Considered one of the most beautiful women of her time, after the death of her first husband, she was regent of San Martino all’Argine, Isola Dovarese, Rivarolo and Commessaggio from 1605 to 1613, due to the fact that her eldest son was still a minor. Her disastrous second marriage to a distant cousin resulted in an accusation of witchcraft and an Inquisition process initiated at the request of her second husband's relatives, including his brother, Ferdinando I, which culminated in her complete rehabilitation. She played a fatal role in the extinction of the main branch of the House of Gonzaga, which initiated the beginning of theWar of the Mantuan Succession.

Life

Early life

Born in Novellara in 1576, Isabella was the eighth of thirteen children of Alfonso I Gonzaga, Count ofNovellara and Bagnoloand Vittoria diCapua,a member of one of the richest and most powerful families in the Kingdom of Naples.

In 1594, Isabella married Ferrante Gonzaga, cadet member of the Gonzaga branch of Sabionetta-Bozzolo, Lord of San Martino all’Argine, Isola Dovarese, Rivarolo and Commessaggio and General of the Army of the Kingdom of Spain. They had seven (or eight) children.

Regent of San Martino all’Argine

In February 1605, Isabella's husband died. Because her oldest son was still a minor, she became regent of his domains, which included the Lordships of San Martino all’Argine, Isola Dovarese, Rivarolo and Commessaggio. In 1609, she also became the regent of the Principality ofBozzolo,the Lordship ofRivarolo di Fuoriand the County ofPomponescowhen her still underage son inherited these domains from his paternal uncle, Giulio Cesare Gonzaga. In historiography, the period of Isabella's regency is assessed by contemporaries as a positive one. Among her achievements were the establishment of an archive and a public notary chamber, which made it possible to improve the judicial system. Thanks to Isabella's actions, feuds under her government quickly coped with the consequences of the devastating flood of 1609.

While being deeply involved in the government of her eldest son's domains, Isabella also worked to ensure the futures of her younger children: Alfonso entered the service of an influential relative,Charles III, Duke of Nevers and Rethel(who later became in Duke of Mantua and Monferrato), from whom he received the title of Marquis of Pomaro. Carlo followed a church career and after studying at theUniversity of Salamanca,took his vows as a monk and headed the Abbey of Lucedio. Luigi, Camillo, Annibale and Federigo all followed a military career and rose to high ranks. Her only daughter and namesake, Isabella, became a nun. In 1613, her oldest son, Scipione, finally attained his legal majority and took over the government of his domains, after which Isabella retired to San Martino, near Mantua.

Duchess consort of Mantua

In 1615, CardinalVincenzo Gonzaga—younger brother ofFerdinando I, Duke of Mantua and Monferrat— settled in the castle of Gazzuolo near San Martino. Despite the education and upbringing received from the Jesuits, the 21-year-old prince exhibited very dissolute behavior, for which he was removed from the Ducal court. When he learned that a middle-aged cousin once considered to be one of the first Italian beauties lived close to him, he decided to pay her a visit: it turned out that the 39-years-old Isabella, mother of eight children, was still beautiful and seductive. Vincenzo fell in love with her, but she refused his advances; then he proposed to her. In August 1616, they secretly married in the chapel of the San Martino palace. Vincenzo askedPope Paul Vfor his release from his ecclesiastical vows. On 5 September of that year, his renouncement of thecardinalatereceived an official approval.

Ferdinando I was against this wedding, as he expected to influence through his younger brother's ecclesiastical status the policy of the Holy See in favor of theHouse of Gonzaga.The Duke turned to the Bishop of Mantua with a request to declare the marriage invalid, in order to return Vincenzo to the cardinalate; his position was shared by his wifeCatherine de' Medici,who even tried to convince her motherChristina of Lorraineto obtain the support of theGrand Duchy of Tuscanyin this matter. At first Vincenzo desperately resisted, but when he was banished toGoitoand deprived of a number of material advantages, he broke down, and in December 1616 agreed with his older brother's demands to have his marriage to Isabella annulled.

Isabella was kept under surveillance for some time in Gazzuolo, but when it was confirmed that she wasn't pregnant, she was allowed to return to San Martino. However, the annulment of her marriage with Vincenzo turned out to be very difficult. Ferdinando I, using the help of his wife's cousin,Queen Marie of France,received the conclusion of theSorbonneprofessors about the possible annulment of the marriage because of the close relationship of the couple; however, this wasn't enough. In Mantua itself, members of the Sabionetta and Novellara branches of the House of Gonzaga spoke out against the divorce.

Ferdinando I, childless in his marriage, understood that his younger brother was his heir, and wanted Vincenzo to marry soon to secure the survival of the dynasty; so, after an unsuccessful attempt to poison Isabella, the Duke accused her ofwitchcraft.The accusations provoked the beginning of the inquisition process, which was opened in the diocese of Mantua in 1622. There were supposed "witnesses" who said that they saw the Dowager Lady of San Martino all’Argine using magical potions. Isabella soon understood that if she went through awitch trialin Mantua, she would likely have no chance to save her life, especially when the accusation of witchcraft was supported by her husband. In 1623, she fled to Rome and appealed her case to the Supreme Inquisition. Thus, a new process was initiated, which was approved by the newPope Urban VIII.Ferdinando I vainly insisted on conducting the inquisition process in Mantua. Isabella, at the insistence of the Duke, was imprisoned in theCastel Sant'Angeloin Rome. But soon, after a thorough investigation, she was cleared of all charges of witchcraft. All the "witnesses" were summoned to Rome, and once there, they recanted their testimonies. During January and May 1624, she was fully rehabilitated. The next attempt of the Duke and her husband to kill her, using hired killers, also failed.

In October 1626, Vincenzo became the new Duke of Mantua and Montferrat, under the name of Vincenzo II. Although the couple lived separately, they were still legally married, so Isabella was given the title of Duchess consort of Mantua and Montferrat. This news reached her in Rome. In April 1627, the Holy See confirmed the validity of the marriage of Isabella and Vincenzo II. In addition, she raised the issue of material compensation for damages caused by her husband and his relatives, as well as her recognition as Duchess. In December 1627, Isabella was widowed for the second time. With the death of her childless husband, the main line of the House of Gonzaga became extinct, and theWar of the Mantuan Successionbegan.
