Duke Galeazzo Maria was assassinated on 26 December 1476, at the hands of several high-ranking officials in the Milanese court. He was succeeded by his son
Gian Galeazzo Maria, then only seven years old. Upon hearing the news, Ludovico hastily returned from France. Together with two other brothers,
Ascanio and Ottaviano, as well as the condottieri
Roberto Sanseverino, Donato del Conte, and Ibletto Fieschi, Ludovico tried to oppose the regency of Bona, believing the duchy was in fact in the hands of the ducal councilor
Cicco Simonetta. The attempt failed and Ludovico was exiled to Pisa, Sforza Maria to Bari, and Ascanio to Perugia. Ottaviano tried to wade across the
Adda to escape and drowned. Roberto Sanseverino fled to France, Donato del Conte was imprisoned in Monza, and Ibletto Fieschi was imprisoned in the Castello Sforzesco. In February 1479, Ludovico and Sforza Maria, supported by
Ferrante of Aragon, entered the Republic of Genora with an army, where they joined Roberto Sanseverino and Ibletto Fieschi. The Duchess Bona and Cicco Simonetta convinced Federico Gonzaga and Ercole d'Este to gather a rival army and come to their rescue. On 1 March 1479, Ludovico and his brother were declared rebels and enemies of the Duchy, and were denied the income they received by virtue of their mother's dowry. After carrying out looting in Pisa, the two returned to La Spezia. In mid-May, peace negotiations began between the two sides. On 29 July, Sforza Maria died near Varese Ligure, allegedly poisoned on the order of Cicco Simonetta. Ferrante appointed Ludovica as the Duke of Bari, succeeding his brother. Following Roberto Sanseverino, on 20 August Ludovico resumed the march to Milan at the head of an army of 8,000 men, crossing the Passo di Centocroci and going up the Sturla Valley. On 23 August he took the citadel of Tortona after having convinced the Castellan Rafagnino Donati to join his cause. He then marched through to Sale,
Castelnuovo Scrivia, Bassignana and
Valenza. After these successes, Simonetta sent Ercole d'Este, Duke of Ferrara, to stop the rebels. Many nobles close to the duchess pushed for reconciliation. Bona finally allowed herself to be persuaded by her lover, Antonio Tassino, who was probably in league with Ludovico, to forgive her brother-in-law. On 7 September, Ludovico entered the castle of Milan. Simonetta was untrusting of Ludovico, and firmly opposed reconciliation. He reportedly said to the Duchess Bona "I will lose my head and you, in time, will lose the state". The Milanese Ghibelline nobility, which included
Pietro Pusterla, took advantage of Ludovico's presence in Milan to try to convince him to get rid of Simonetta, reminding him of all the sufferings that he and his brothers had suffered because of Simonetta. Ludovico, however, did not consider Simonetta a danger and judged it unnecessary to condemn to death a man now quite old and sick with gout.
Death of Cicco Simonetta and exile of Duchess Bona Having secured the city, Ludovico recalled his brother Ascanio and Roberto Sanseverino to Milan. He sent envoys to forge or re-establish alliances with
Lorenzo de' Medici, King Ferrante, and Pope Sixtus IV, and to prevent an alliance against him between the Swiss and the Republic of Venice. Meanwhile, the Ghibelline nobility who had helped him in his rise to power, had lost Ludovico's favor and aligned themselves with his brother Ascanio. Ludovico, persuaded by Sanseverino, ordered the arrest of his brother and his exile in Ferrara. Pietro Pusterla, Giovanni Borromeo, Antonio Marliani, and many others of the Ghibelline faction were also exiled. On 30 October, Cicco Simonetta was beheaded at
Visconti Castle in Pavia, overlooking
Visconteo Park. The death of Simonetta benefited
Antonio Tassino, Simonetta's rival at court, who became increasingly arrogant.
The Corio tells that when Ludovico and other Milanese nobles went to visit Tassino he would make them wait a long time outside the door until he had finished combing his hair. Tassino managed to convince Duchess Bona to replace Filippo Eustachi, prefect of the castle of Porta Giovia, with his father Gabriello. The prefect did not comply with the request and kept the oath made to the late Duke Galeazzo Maria to keep the castle until the age of majority of Gian Galeazzo. Ludovico decided to secretly bring his nephews Gian Galeazzo and Ermes into the castle, under the pretext of protecting them from the ambition of Tassino. He convened his council, and Bona was forced to sign the sentence of exile for Tassino and his family. Due to the forced separation from her lover, Bona gave signs of so-called hysteria. She tried to leave the duchy and threatened suicide if she was prevented, which persuaded Ludovico and Roberto Sanseverino to let her leave for France. On 3 November 1480, Bona ceded the regency to Ludovico, who was appointed tutor of the young duke Gian Galeazzo, At the insistence of his son, Ludovico decided to no longer reside in Abbiategrasso.In 1481, perhaps orchestrated by Bona, there was an attempted poisoning against Ludovico and Roberto Sanseverino perpetrated by Cristoforo Moschioni, along with co-conspirators, the secretary of the Duchess Luigi Becchetti and the doctor Ambrogio Grifi. Moschioni was found innocent. The same year there was a second conspiracy planned by the Duchess against Ludovico, but once again it failed. The intercession of the Kingdom of France and the Duchy of Savoy prevented Bona from facing trial.
To the regency of the duchy (1480–1494) Engagement to Beatrice d'Este Ludovico initially planned to become Duke of Milan by marrying his sister-in-law Bona. Bona, however, was in love with Tassino, and so sought an alternative marriage for Ludovico. In 1480, she attempted to arrange a marriage with
Ercole d'Este's eldest daughter
Isabella. Unbeknownst to Bona, a few days earlier Isabella had been promised to Francesco Gonzaga, Marquis of Mantua. The second daughter
Beatrice, at the time only five years old, was instead selected for Ludovico. Ludovico was persuaded by Bona and was supportive of the marriage. Beatrice remained in Ferrara until 1485, when Ludovica persuaded her family to allow her to return to Milan to be educated in a court more suited to her role.
War of Ferrara In 1482, the Republic of Venice along with the
Papal States entered into war against the
Duchy of Ferrara. Ludovico and the Duchy of Milan entered the war in favour of his future father-in-law, Ercole d'Este. To support the war, Ludovico sent forces commanded by
Federico da Montefeltro, then, after the death of da Montefeltro, his half-brother Sforza Secondo. The Venetian army was commanded by
Roberto Sanseverino d'Aragona. On 6 January 1483, Pope Sixtus IV abandoned the alliance with the Venetians and allied with Ferrara. The Venetians, with the help of
Costanzo Sforza, devised a plan to make Ludovico abandon his alliance with Ferrara. On 15 July, the Venetian army crossed the Adda. Ludovico met with Alfonso of Aragon and other representatives of the alliance in Cremona and decided to immediately counterattack the Venetians. On 22 July, King Alfonso gathered the army in Monza. The following day the Venetian army led by Roberto Sanseverino, realizing that their plan had failed, retreated to Bergamo. In the summer of 1483, Gian Francesco and
Galeazzo Sanseverino, Roberto's sons, defected from the Venetian camp to pass respectively to the service of Alfonso of Aragon and Ludovico. Ludovico and Galeazzo would become close friends, and they remained as such throughout their lives. On 10 August, Ludovico and his brother Ascanio marched to Bergamo, forcing the surrender of many castles and threatening Bergamo itself. They managed to capture
Romano after a three-day siege after which Ludovico returned to Milan. Despite repeated success, Ferrara and its allies were unable to deal a decisive defeat to the Venetians. On 24 April 1484, the allies of Ferrara held a war council, meeting in the castle of Porta Giovia. There they decided to continue the war against the Republic of Venice, however, disagreements soon arose between Ludovico and Alfonso of Aragon. The Venetians, knowing that Ludovico had incurred massive debts in support of his father-in-law, offered him peace in exchange for money, provided that they retained control of the
Polesine. Ludovico accepted and signed the agreement on 7 August in Bagnolo, against Ercole d'Este's wishes.
Marriage and private life After the war, Ludovico's fiancée Beatrice had reached an age suitable for the wedding and her father was eager for a date to be set. Ludovico, however, as the Este ambassador recorded, had met a woman named
Cecilia Gallerani. She was described as being very beautiful and was often at Ludovico's side. Ludovico postponed his marriage to Beatrice three times, frustrating his future in-laws, who believed that he no longer intended to marry their daughter. Those close to Ludovico had been pressuring him for years to replace his nephew as the Duke of Milan, and wished for Beatrice to have a legitimate heir for him as soon as possible. In 1490, after thirteen months away, Ludovico's nephew Gian Galeazzo consummated the marriage with his wife Isabella of Aragon, who within a few days found herself pregnant. This event caused on the one hand the irritation Ludovico's allies, and on the other convinced him of the need to marry Beatrice. at 19, contained in the donation certificate dated 28 January 1494 with which her husband assigned her numerous lands, now preserved in the
British Library in London The wedding was set for the following January, and on 29 December 1490, the wedding procession left Ferrara to bring Beatrice to Milan. She was accompanied by her mother and other relatives. Beatrice's brother Alfonso and cousin Ercole were to be married to two princesses of the Sforza house on the same occasion: the first Anna Maria, daughter of the late Galeazzo Maria and niece of Ludovico, the second Angela, daughter of Carlo Sforza and Bianca Simonetta (daughter of Cicco Simonetta). On 18 January 1491, in a simple ceremony, Ludovico married Beatrice in the Ducal Chapel of the
castle of Pavia. He had wanted the wedding to be celebrated in Pavia and not in Milan so as not to give the impression of attempting to challenge Gian Galeazzo, who had married Isabella of Aragon in the Duomo a few months earlier. This aroused new concerns from his father-in-law Ercole, who urged for the marriage to be consummated immediately.
Marital bond After the marriage, Ludovico became enamoured with his new wife. "S.r Ludovico hardly ever takes his eyes off the Duchess of Bari" wrote Tebaldo Tebaldi in August 1492, and already a short time after the wedding Galeazzo Visconti declared "There is such a great love between them that I don't think two people can love each other more". Ludovico was often seen kissing and caressing his wife, and he would stand beside bed for most of the day when she was sick. In a letter he wrote of her: "she is dearer to me than the light of the sun". It is uncertain whether Beatrice reciprocated this affection, but some historians believe she did. Ludovico's contemporaries noted, not without amazement, that Beatrice followed him everywhere, even in the course of her pregnancies. Her commitment to following Ludovico sometimes endangered her life, contrary to the custom of the time where women often remained to govern the house during their husbands absences. They were, in the short years they lived together, the model of an ideal couple. The 15-year-old princess quickly charmed the Milanese court with her joyfulness and laughter. She loved extravagance, and helped make a reputation for Sforza Castle as a place of sumptuous festivals and balls. She enjoyed entertaining philosophers, poets, diplomats, and soldiers. Beatrice had good taste, and it is said that under her prompting her husband's patronage of artists became more selective. During this time artists such as
Leonardo da Vinci and
Donato Bramante were employed at the court.
Ascension as Duke of Milan and the Italian Wars '', , by an unknown author: on the left, Ludovico with his son Cesare; on the right, Beatrice with her son
Ercole Massimiliano Gian Galeazzo and his wife Isabella, after their lavish marriage, left Milan to set up court in Pavia. Gian Galeazzo did not have the desire to rule and he was happy to leave his uncle Ludovico in charge. His wife Isabella, however, turned out to be more ambitious and came into conflict with her cousin Beatrice. After Beatrice gave birth on 25 January 1493 to their first son,
Ercole Massimiliano, she wished to have him, and not Isabella's son, appointed as Count of Pavia. The title of Count of Pavia was typically reserved for the heir to the Duchy of Milan. Isabella requested the intervention of her grandfather King Ferrante of Naples, so that her husband, now of age, would be given control of the duchy. Ferrante, however, had no desire to intercede, fearing the possibility of starting a war. He declared that he loved both granddaughters in the same way and asked them to settle matters while he was alive. When Ferrante died, his successor
Alfonso sided with his daughter Isabella. In an act of aggression against Ludovico, he occupied the city of Bari. To respond to the occupation, Ludovico allied himself with
Emperor Maximilian and with the King of France
Charles VIII. King Charles mobilized his armies south and conquered the
kingdom of Naples, which Charles considered his legitimate possession, having allegedly been stolen from France by the Aragonese. Emperor Maximilian promised to publicly recognize Ludovico's succession to the duchy and to defend his interests, thus legitimizing the usurpation. To solidify the pact he married
Bianca Maria Sforza, sister of the young Gian Galeazzo. This marriage brought him the sum of 400,000 ducats as a dowry, plus another 100,000 for the investiture, as well as many gifts. On 11 September 1494, Charles VIII arrived in Asti and was received with great honors by Ludovico and Beatrice. With him also came his cousin Louis d'Orléans, who believed he was entitled to the title Duke of Milan, being a descendant of
Valentina Visconti. Despite the latent hostilities, the first months of the visit passed without issue, and Ludovico used the charm of his wife Beatrice to placate the French and thus distract them. Eventually, Ludovico became jealous of a relationship forming between the Baron of Beauvau and his wife Beatrice, and he chose to send Beatrice back to Milan. ==Duke of Milan==
