Galeazzo Maria Sforza, Duke of Milan (d. 1476)

Galeazzo Maria Sforza (born 24 January 1444, died 26 December 1476) held the distinguished title of the fifth Duke of Milan, reigning from 1466 until his untimely assassination a mere decade later. His tenure, though brief, was profoundly marked by a notorious reputation for being lustful, cruel, and tyrannical, attributes that ultimately contributed to his violent demise.

The Lineage of Power: Birth and Early Life

Born into one of Renaissance Italy's most formidable dynasties, Galeazzo Maria Sforza was the legitimate son of Francesco Sforza and Bianca Maria Visconti. His father, Francesco Sforza, was a highly successful and popular condottiero, a mercenary captain whose military prowess and strategic acumen allowed him to transcend his humble origins. Francesco notably forged a crucial alliance with Cosimo de' Medici, the de facto ruler of Florence, a partnership that solidified the Sforza family's political standing in the intricate web of Italian states.

In 1450, following the death of Filippo Maria Visconti, the last legitimate Visconti Duke of Milan, Francesco Sforza skillfully navigated the ensuing power vacuum. Despite the establishment of the short-lived Ambrosian Republic, Francesco, supported by his wife Bianca Maria Visconti's legitimate claim to the Duchy through her father, ultimately seized control of Milan. This pivotal event ushered in the Sforza dynasty, transforming Milan into a major European power and setting the stage for Galeazzo Maria's eventual succession.

A Decade of Ducal Rule: Patronage and Tyranny

Galeazzo Maria Sforza inherited the Duchy of Milan at the age of 22, and his reign was a complex tapestry woven with threads of both remarkable cultural patronage and extreme despotism. While he was a significant patron of music, commissioning lavish compositions and fostering a vibrant court culture that attracted renowned artists and musicians, his personal conduct frequently overshadowed these achievements. He became infamous for his arbitrary acts of cruelty, his insatiable lust, and a tyrannical style of governance that alienated many of his subjects and courtiers.

Contemporary chroniclers, such as Bernardino Corio, often depicted him in a highly critical light, famously stating that Galeazzo Maria was "a man who did great follies and dishonest things not to write." These "follies" included severe punishments for minor offenses, such as the execution of a hunter caught trespassing in his preserve, whose entrails were reportedly forced upon him. His oppressive taxation policies, designed to fund his extravagant court and military endeavors, further fueled widespread resentment among the Milanese populace.

Strategic Marriages and Political Alliances

Galeazzo Maria Sforza's marital history was intrinsically linked to the political landscape of Renaissance Italy, aimed at forging crucial alliances to bolster the Sforza power. His first marriage was into the influential Gonzaga family, rulers of the Marquisate of Mantua. He wed Dorotea Gonzaga, daughter of Ludovico III Gonzaga and Barbara of Brandenburg.

Upon Dorotea's premature death, Galeazzo Maria subsequently married Bona of Savoy. Bona was the daughter of Louis, Duke of Savoy, and Anne of Cyprus. This union further cemented ties with the powerful House of Savoy, expanding the Sforza's network of alliances. Bona of Savoy would later play a significant role as regent for their young son, Gian Galeazzo Sforza, after Galeazzo Maria's death.

The Assassination and its Aftermath

The combination of Galeazzo Maria Sforza's oppressive rule, his flagrant disregard for justice, and his personal cruelties cultivated a fertile ground for dissent. On 26 December 1476, the Feast of Saint Stephen, Galeazzo Maria was assassinated within the Church of Santo Stefano in Milan. The conspiracy against him involved several noblemen who harbored deep-seated grievances, notably Carlo Visconti, Gerolamo Olgiati, and Giovanni Andrea Lampugnani. Their primary motivation was to liberate Milan from what they perceived as his unbearable tyranny and to restore a semblance of republican liberty, though their hopes were ultimately unfulfilled.

Galeazzo Maria's assassination sent shockwaves across Italy, highlighting the volatile nature of Renaissance politics and the precarious position of even the most powerful rulers. His death left the Duchy of Milan in a state of political instability, with his young son, Gian Galeazzo Sforza, succeeding him under the regency of Bona of Savoy. However, real power soon fell into the hands of Galeazzo Maria's ambitious younger brother, Ludovico Sforza, known as "Il Moro," who would eventually usurp the ducal title.
