The Italian merchant prince Cosimo de' Medici (1389-1464) was the unofficial and benevolent despot of Florence, contributing much to making it the intellectual and cultural jewel of 15th-century Europe. The dynasty he founded ruled Florence until 1494.

Cosimo de' Medici was born on Sept. 27, 1389, the son of Giovanni de' Medici, who founded the family's legendary fortune, amassing enormous sums in trade and banking. After his father died in 1429, Cosimo continued the family's commercial and financial practices with great success. He brought goods of little weight and high value from the East and lent money to the princely houses of Europe.

Cosimo also adopted the policy, already traditional in his family, of supporting the lesser guilds and the poor against the wealthy aristocracy which ruled the city. These oligarchs became jealous of Cosimo's popularity and fearful of his democratic tendencies. Consequently they sought to destroy him and his family. In 1433, spurred on by Rinaldo degli Albizzi, the most influential of their number, they had Cosimo arrested with the intention of putting him to death. He was exiled instead when, from his place of imprisonment, he succeeded in buying the favor of Bernardo Guadagni, the gonfalonier of justice, for 1,000 ducats (about $25,000).

One year later, in October 1434, the sentence of exile was overturned by a new government favorable to Cosimo, and he returned to the city in triumph. From that time until his death he controlled both the foreign and domestic affairs of Florence, using his prestige and his money to keep his adherents in the government. Cosimo himself took public office only briefly. He believed it prudent to keep the institutions of government intact and to rule quietly, so as not to injure the republican sensibilities of the people.

His despotism established, Cosimo promptly reformed the system of taxation, changing from a fixed income tax to a graduated one. This placed a heavier burden on the wealthy, who grumbled that the Medici tyrant was using the tax as a weapon against them. The middle class and the poorer citizens, who were Cosimo's strength, were delighted and became even more ardent in their support, particularly when they saw that the funds gained through taxation, amplified by substantial contributions from Cosimo's own pocket, were put to use in public projects.

Cosimo employed the architectural skills of Michelozzo to build his palace and, in 1437, the Dominican convent of S. Marco. He commissioned Filippo Brunelleschi to restore the church of S. Lorenzo, which was in dire need of repair. The cloisters of Fiesole owe their erection to Cosimo, who added to these monuments of his munificence country villas of contemporary style at both Fiesole and Careggi.

Along with the physical adornment of Florence and its environs, Cosimo provided for its cultural life. He sent his ships to the East to gather the precious manuscripts of ancient writers, and he hired scribes to copy what he could not buy. He added to this growing collection the private library of Niccolò Niccoli, an enthusiastic bibliophile who left his books to Cosimo in gratitude for generous loans which had saved him from financial ruin. These valuable manuscripts were distributed to the monastery of S. Marco in Florence and the abbey at Fiesole, except for some which Cosimo kept in his own home. These collections were open to the public.

The growing accessibility of the materials of scholarship and the persuasion of Greek scholars, to whom he was always a gracious host, inspired Cosimo to found the Platonic Academy, an institution for the translation of Plato's works and the propagation of his ideas. Marsilio Ficino, a humanist of great skill, was made president of the academy in 1458. The patronage of the tyrant did not stop here. His largesse was enjoyed not only by architects and scholars but also by some of the greatest sculptors and painters of the quattrocento, among them Donatello and Fra Filippo Lippi.

In spite of his riches and the lavish entertainments he provided for his guests, Cosimo lived modestly. He ate and drank moderately and simply and worked long, regular hours. He dressed without ostentation and was accessible to the humblest Florentine. His generosity, mildness, and wit were legendary. Upon his death on Aug. 1, 1464, a grateful city decreed that on his tomb should be inscribed the words Pater Patriae (father of his country).

Further Reading

The best biography of Cosimo is still K. Dorothea Ewart Vernon, Cosimo de' Medici (1899). A scholarly treatment of Cosimo is in George Frederick Young, The Medici (1930). A recent history of the Medici which includes a portrait of Cosimo is Marcel Brion, The Medici: A Great Florentine Family (1969), a large-format book rich in color plates. Also very useful on all the Medici is Ferdinand Schevill, History of Florence (1936), also available in a paperback edition (2 vols., 1963).

(kô'zēmō dā mĕ'dĭchē, Ital. mā'dēchē) , 1389–1464, Italian merchant prince, first of the Medici family to rule Florence. He is often called Cosimo the Elder. After the death of his father, Giovanni di Bicci de' Medici, Cosimo and his family were banished (1433) from Florence by a faction headed by the powerful Albizzi family. He returned a year later and, supported by the people, soon became the acknowledged leading citizen of the republic. An able financier, he vastly expanded the family's banking business. In spite of his lavish expenses for the state, for charities, and for the arts and learning, he doubled his fortune. He respected the republican institutions of the city, always sought popular support, and made his power as little felt as possible. Guiding Florentine foreign policy, he sought a balance of power among the Italian states. From the traditional alliance with Venice against Milan, he shifted to an alliance with the Sforza family, helping the Sforzas to gain control over Milan. Cosimo's claim to greatness, however, rests chiefly on his generosity toward artists and scholars. He founded the famous Medici Library and an academy for Greek studies (headed by Marsilio Ficino), built extensively in Florence, and protected such artists as Brunnelleschi, Donatello, Ghiberti, and Luca della Robbia. After his death Florence voted him the official title Pater Patriae. His son, Piero de' Medici, known as Il Gottoso [the gouty], succeeded as head of the family.
