Lorenzo de' Medici, Duke of Urbino

• 1. Introduction

  ›

  Lorenzo di Piero de' Medici was born on the 12th of September 1492 into one of the most powerful families in Italy, and he died at just twenty-six years old. In that brief span, he ruled Florence, fought a war for a dukedom, married a French countess, and fathered a daughter who would one day sit on the throne of France. What makes his story strange is not what he achieved, but what his short life set in motion. Who was this young man who convinced a pope to hand him a duchy? How did a wounded soldier become the father of a French queen? And why do historians still argue about which tomb in Florence is actually his?

• 2. A Medici by Blood

  ›

  Lorenzo's paternal grandfather was Lorenzo the Magnificent, the figure whose name has come to define the Florentine Renaissance in popular memory. His grandmother on that side was Clarice Orsini, and his maternal grandparents were Roberto Orsini, Count of Tagliacozzo, and his wife Catherine of San Severino. On both sides of the family, Lorenzo II was connected to powerful Italian noble houses. His mother, Alfonsina Orsini, gave him a double inheritance of Orsini blood. His father was Piero di Lorenzo de' Medici. Sharing his grandfather's name would later cause confusion that lingers to this day: visitors to the Medici Chapel in Florence have long mistaken the Duke's tomb for that of Lorenzo the Magnificent.

• 3. The War for Urbino

  ›

  In 1516, the year he became lord of Florence after his uncle Giuliano de' Medici died, Lorenzo was twenty-four years old. He had been appointed Captain of the Florentine militia, yet he had little patience for the city's republican structures. He persuaded his other uncle, Pope Leo X, to grant him the Duchy of Urbino that same year. The previous duke, Francesco Maria I della Rovere, was not prepared to accept that arrangement quietly. What followed was the War of Urbino, a grinding conflict in which della Rovere recaptured the city, only for Lorenzo to retake it at the head of a papal army ten thousand men strong. Lorenzo was wounded in the fighting and withdrew to Tuscany to recover. A treaty in September 1517 finally restored Urbino to his control, though the duchy would remain in Medici hands for only two more years before reverting to the della Rovere family in 1521.

• 4. Marriage, Death, and a Daughter Left Behind

  ›

  On the 13th of June 1518, Lorenzo married Madeleine de La Tour, the daughter of the Count of Auvergne. The union was brief. Madeleine died on the 28th of April 1519, and Lorenzo followed her to the grave just six days later, on the 4th of May 1519. Their daughter Catherine had been born that same year. With both parents dead before she could form memories of them, Catherine was raised by the two Medici popes, Leo X and Clement VII, and the surrogates they appointed. It was Pope Clement VII who would later arrange Catherine's marriage to the French prince who would become King Henry II of France, a match that carried her from a Florentine orphan's upbringing to the court of one of Europe's most powerful kingdoms.

• 5. The Illegitimate Heir

  ›

  Catherine was not Lorenzo's only child. By Simonetta, a servant girl in his mother Alfonsina's household, he had a son named Alessandro de' Medici, born in 1510. Alessandro was recognised but illegitimate. After Lorenzo's death, Alessandro inherited his estate and went on to become the first Duke of Florence. His story ended violently: he was assassinated in 1537 by his cousin, known to history as Lorenzaccio. Alessandro's death without a clear heir caused the ducal title to pass to Cosimo I de' Medici, a member of the family's junior branch. In this way, Lorenzo II's line shaped the succession of Florence even beyond the lives of his own children.

• 6. Machiavelli's Dedication

  ›

  Niccolò Machiavelli addressed The Prince to Lorenzo, offering the treatise as a guide to the tactics a ruler should use to hold onto power. The dedication placed Lorenzo at the centre of one of the most consequential works of political writing in European history. Whether Lorenzo read it closely or absorbed its lessons is not recorded. The argument over his tomb in the Medici Chapel of San Lorenzo carries a similar ambiguity: historian Richard Trexler contended that Lorenzo, as Captain of the Florentine militia, must be the figure holding the baton in Michelangelo's sculpture rather than the pensive seated figure traditionally called the Pensieroso. Trexler also pointed out that the Pensieroso holds a mappa, a symbol of military authority in ancient Rome, which he argued fits Lorenzo's uncle Giuliano di Lorenzo more naturally. The question of which face looks out from Michelangelo's marble has never been settled with certainty.
