Cosimo di Giovanni de' Medici (27 September 1389 – 1 August 1464) was an Italian banker and politician who became thede facto first ruler ofFlorence during theItalian Renaissance, establishing theMedici family as its effective leaders for generations. His power derived from his wealth as a banker and intermarriage with other rich and powerful families.[1] He was a patron of arts, learning, and architecture.[2] He spent over 600,000gold florins[3][4] (approx. $500 million inflation adjusted) on art and culture, includingDonatello'sDavid, the first freestandingnude male sculpture sinceantiquity.
Despite his influence, his power was not absolute; he was viewed by fellow Florentine politicians as first among equals rather than an autocrat.[5] Florence's legislative councils resisted his proposals throughout his political career, even sending him into exile from 1433 to 1434.
Cosimo de' Medici was born inFlorence toGiovanni di Bicci de' Medici and his wifePiccarda Bueri on 27 September 1389.[6] At the time, it was customary to indicate the name of one's father in one's name for the purpose of distinguishing the identities of two like-named individuals; thus, Giovanni was the son of Bicci, and Cosimo's name was properly rendered Cosimo di Giovanni de' Medici. He was born along with a twin brother Damiano, who survived only a short time. The twins were named afterSaints Cosmas and Damian, whose feast day was then celebrated on 27 September; Cosimo would later celebrate his own birthday on that day, his "name day", rather than on the actual date of his birth.[7] Cosimo also had a brother Lorenzo, known as "Lorenzo the Elder", who was some six years younger and participated in the family's banking enterprise.

Cosimo inherited both his wealth and his expertise in banking from his father Giovanni, who had gone from being a moneylender to join the bank of his relative Vieri di Cambio de' Medici. Giovanni had been running Vieri's branch in Rome independently since the dissolution of the latter's bank into three separate and independent entities until 1397, when he leftRome to return to Florence to found his own bank, theMedici Bank. Over the next two decades, the Medici Bank opened branches in Rome,Geneva,Venice, and temporarily inNaples; the majority of profits was derived from Rome. The branch manager in Rome was a papaldepositario generale who managed Church finances in return for a commission.[8] Cosimo would later expand the bank throughout western Europe and opened offices inLondon,Pisa,Avignon,Bruges,Milan,[9] andLübeck.[10] The far-flung branches of the Medici rendered it the best bank for the business of the papacy, since it enabled bishoprics in many parts of Europe to pay their fees into the nearest branch, whose manager would then issue a papal license, and the popes could more easily order a variety of wares – such as spices, textiles, and relics – through the bankers' wholesale trade.[10] In fifteen years, Giovanni would make a profit of 290,791 florins.[9]
In 1415, Cosimo allegedly accompanied theAntipope John XXIII at theCouncil of Constance. In 1410, Giovanni lent John XXIII, then simply known as Baldassare Cossa, the money to buy himself the office ofcardinal, which he repaid by making the Medici Bank head of all papal finances once he claimed the papacy. This gave the Medici family tremendous power, allowing them, for instance, to threaten defaulting debtors with excommunication.[11] But misfortune hit the Medici Bank in 1415, when the Council of Constance unseated John XXIII, thus taking away the near monopoly they had held on the finances of theRoman Curia; thereafter, the Medici Bank had to compete with other banks. However, after the Spini Bank of Florence went insolvent in 1420, they again secured priority.[8] John XXIII, facing the enmity of a church council at which he was accused of a large variety of offenses against the Church, was confined bySigismund, Holy Roman Emperor toHeidelberg Castle until the Medici paid his ransom and granted him asylum.[12]In the same year as John's dethronement (1415), Cosimo was named a "Priore [it] of the Republic [of Florence]". Later he acted frequently as anambassador for Florence and demonstrated a prudence for which he became renowned.

About 1415, Cosimo marriedContessina de' Bardi (the daughter of Alessandro di Sozzo Bardi, count ofVernio, and Camilla Pannocchieschi).[13] The wedding was arranged by his father as an effort to reaffirm relations with the long-standing nobleBardi family, who had operated one of the richest banks in Europe until its spectacular collapse in 1345; they nevertheless remained highly influential in the financial sphere. Only part of the Bardi family were involved in this marriage alliance, for some of the branches considered themselves the opponents of the Medici clan.[14][15] The couple had two sons:Piero the Gouty (b. 1416) andGiovanni de' Medici (b. 1421).[16] Cosimo also had an illegitimate son,Carlo, by aCircassian slave, who would go on to become aprelate.
Giovanni withdrew from the Medici Bank in 1420, leaving its leadership to both of his surviving sons. He left them 179,221 florins upon his death in 1429.[17] Two-thirds of this came from the business in Rome, while only a tenth came from Florence; even Venice offered better returns than Florence. The brothers would earn two-thirds of the profits from the bank, with the other third going to a partner. Besides the bank, the family owned much land in the area surrounding Florence, includingMugello, the place from which the family originally came.[18]
Cosimo's power over Florence stemmed from his wealth, which he used to control the votes of office holders in the municipal councils, most importantly theSignoria of Florence. As Florence was proud of its "democracy", he pretended to have little political ambition and did not often hold public office. Enea Silvio Piccolomini, Bishop ofSiena and laterPope Pius II, said of him:
Political questions are settled in [Cosimo's] house. The man he chooses holds office... He is who decides peace and war... He is king in all but name.[19]

In 1433, Cosimo's power over Florence began to look like a menace to the anti-Medici party led by figures such asPalla Strozzi and theAlbizzi family, headed byRinaldo degli Albizzi. In September of that year, Cosimo was imprisoned in thePalazzo Vecchio for his part in the failure in 1429-30 to conquer theRepublic of Lucca, but he managed to turn the jail term into one of exile. Some prominent Florentines, such asFrancesco Filelfo, demanded his execution,[21] a fate that may have been almost certain without the intervention of the monkAmbrogio Traversari on his behalf.[5] Cosimo travelled toPadua and then toVenice, taking his bank along with him and finding friends and sympathizers wherever he went for his willingness to accept exile rather than resume the bloody conflicts that had chronically afflicted the streets of Florence. Venice sent an envoy to Florence on his behalf and requested that they rescind the order of banishment. When they refused, Cosimo settled down in Venice, his brother Lorenzo accompanying him. However, prompted by his influence and his money, others followed him, such as the architectMichelozzo, whom Cosimo commissioned to design a library as a gift to the Venetian people.[22] Within a year, the flight of capital from Florence was so great that the decree of exile had to be lifted. Cosimo returned a year later, in 1434, to influence the government of Florence (especially through thePitti andSoderini families) for the last 30 years of his life of 74 years.[23]
Cosimo's time in exile instilled in him the need to quash the factionalism that resulted in his exile in the first place. In order to do this, he instigated a series of constitutional changes with the help of favourable priors in the Signoria to secure his power through influence.
Following the death ofFilippo Maria Visconti, who had ruled theDuchy of Milan from 1412 until his death in 1447, Cosimo sentFrancesco I Sforza to establish himself in Milan to prevent an impending military advance from theRepublic of Venice. Francesco Sforza was acondottiere, amercenary soldier who had stolen land from the papacy and proclaimed himself its lord. He had yearned to establish himself at Milan as well, an ambition that was aided by the fact that the current Visconti head lacked legitimate children save for a daughter, Bianca, whom Sforza ultimately married in November 1441 after a failed attempt at winning her hand from her father.[24] The resultant balance of power with Milan and Florence on the one side and Venice and theKingdom of Naples on the other created nearly half a century of peace that enabled the development of theRenaissance in Italy.[25] However, despite the benefits to Florence from keeping Venice at bay, the intervention in Milan was unpopular among Cosimo's fellow citizens, primarily because they were called upon to finance the Sforza succession. The Milanese made a brief attempt at democracy before Sforza was finally acclaimed duke by the city in February 1450.[26]
In terms of foreign policy, Cosimo worked to create peace in northern Italy through the creation of a balance of power betweenFlorence,Naples, Venice andMilan during thewars in Lombardy between 1423 and 1454 and the discouragement of outside powers (notably the French and theHoly Roman Empire) from interfering in Italian affairs. In 1439, he was instrumental in convincing PopeEugene IV to move theEcumenicalCouncil of Ferrara to Florence. The arrival of many notableByzantine figures from theEastern Roman Empire, including EmperorJohn VIII Palaiologos, for this event further inspired the growing interest in ancient Greek arts and literature.[27]
"[Cosimo was] the father of a line of princes, whose name and age are almost synonymous with the restoration of learning; his credit was ennobled into fame; his riches were dedicated to the service of mankind; he corresponded at once with Cairo and London; and a cargo of Indian spices and Greek books were often imported in the same vessel."
Cosimo de' Medici used his personal fortune to control the Florentine political system and to sponsor orators, poets and philosophers,[29] as well as a series of artistic accomplishments.[30]
Cosimo was also noted for his patronage of culture and the arts during the Renaissance and spent the family fortune liberally to enrich the civic life of Florence. According toSalviati'sZibaldone, Cosimo stated: "All those things have given me the greatest satisfaction and contentment because they are not only for the honour of God but are likewise for my own remembrance. For fifty years, I have done nothing else but earn money and spend money; and it became clear that spending money gives me greater pleasure than earning it."[31]Additionally, his patronage of the arts both recognized and proclaimed the humanistic responsibility of the civic duty that came with wealth.[32]
Cosimo hired the youngMichelozzo Michelozzi to create what is today perhaps the prototypical Florentinepalazzo, the austere and magnificentPalazzo Medici. The building still includes, as its only 15th-century interior that is largely intact, the Magi Chapel frescoed byBenozzo Gozzoli, completed in 1461 with portraits of members of the Medici family parading through Tuscany in the guise of the Three Wise Men. He was a patron and confidante ofFra Angelico,Fra Filippo Lippi, andDonatello, whose famedDavid andJudith Slaying Holofernes were Medici commissions. His patronage enabled the eccentric and bankrupt architectBrunelleschi to complete the dome ofSanta Maria del Fiore (the "Duomo") in 1436.[33]
In 1444, Cosimo de' Medici founded thefirst public library in Florence, atSan Marco, which was of central importance to thehumanist movement in Florence during the Renaissance. It was designed byMichelozzo, a student ofLorenzo Ghiberti who later collaborated withDonatello and was also a good friend and patron to Cosimo. Cosimo contributed the funds necessary to repair the library and provide it with a book collection, which people were allowed to use at no charge. "That Cosimo de'Medici was able to finance the construction of such a site placed him in a privileged position of leadership in the city. He hand-selected those individuals who were given access to this laboratory of learning, and, through this social dynamic, he actively shaped the politics of the Republic."[34] He also commissioned Michelozzo to design a library for his grandson, Lorenzo de' Medici. His first library, however, was designed by Michelozzo while the two were in Venice, where Cosimo had been temporarily exiled. In 1433, in gratitude for the hospitality of that city, he left it as a gift, his only such work outside Florence.[35] His libraries were noted for their Renaissance style of architecture and distinguished artwork.
Cosimo had grown up with only three books, but by the time he was thirty, his collection had grown to 70 volumes. After being introduced to humanism by a group ofliterati who had asked for his help in preserving books, he grew to love the movement and gladly sponsored the effort to renew Greek and Roman civilization through literature, for which book collecting was a central activity. "Heartened by the romantic wanderlust of a true bibliophile, the austere banker even embarked on several journeys in the hunt for books, while guaranteeing just about any undertaking that involved books. He financed trips to nearly every European town as well as to Syria, Egypt, and Greece organized byPoggio Bracciolini, his chief book scout."[35] He engaged 45 copyists under the booksellerVespasiano da Bisticci to transcribe manuscripts and paid off the debts ofNiccolò de' Niccoli after his death in exchange for control over his collection of some 800 manuscripts valued at around 6,000 florins.[36] These manuscripts that Cosimo acquired from Niccoli would later be the cornerstone of theLaurentian Library, a library in Florence founded by Cosimo's grandson,Lorenzo de' Medici.[37]
In the realm of philosophy, Cosimo, influenced by the lectures ofGemistus Plethon, supportedMarsilio Ficino and his attempts at revivingNeo-Platonism. Cosimo commissioned Ficino's Latin translation of the complete works ofPlato (the first ever complete translation) and collected a vast library that he shared with intellectuals such asNiccolò de' Niccoli andLeonardo Bruni.[38] He also established aPlatonic Academy in Florence in 1445.[39] He provided his grandson Lorenzo de' Medici with an education in thestudia humanitatis. Cosimo certainly had an influence on Renaissance intellectual life, but it was Lorenzo who would later be deemed to have been the greatest patron.[40][41][42]
Roberto Rossellini's three-part television miniseriesThe Age of the Medici (1973) has Cosimo as its central character (the original Italian title isL'età di Cosimo de' Medici, meaning "The Age of Cosimo de' Medici"). The first part,The Exile of Cosimo, and the second part,The Power of Cosimo, focus on Cosimo's political struggles and on his patronage of the arts and sciences in Florence. Cosimo is portrayed by Italian actorMarcello Di Falco.[43]

"Cosimo de' Medici... [was] a citizen of rare wisdom and inestimable riches, and therefore most celebrated all over Europe, especially because he had spent over 400,000 ducats in building churches, monasteries and other sumptuous edifices not only in his own country but in many other parts of the world, doing all this with admirable magnificence and truly regal spirit, since he had been more concerned with immortalizing his name than providing for his descendants."
