first of the Medici family to rise to the highest power was Giovanni d'Averardo de' Medici (known as Giovanni di Bicci), 1360–1429, who, a wealthy banker living in what is now the Piazza del Duomo, was well known for his philanthropy and interest in the welfare of the Florentines, but does not come much into public notice until 1401, when he was appointed one of the judges in the Baptistery door competition. He was a retiring, watchful man. Whether he was personally ambitious is not too evident, but he was opposed to tyranny and was the steady foe of the Albizzi faction, who at that time were endeavouring to obtain supreme power in Florentine affairs. In 1419 Giovanni increased his popularity by founding the Spedale degli Innocenti, and in 1421 he was elected gonfalonier, or, as we might now say, President of the Republic. In this capacity he made his position secure and reduced the nobles (chief of whom was Niccolò da Uzzano) to political weakness. Giovanni died in 1429, leaving one son, Cosimo, aged forty, a second, Lorenzo, aged thirtyfour, a fragrant memory and an immense fortune.
To Lorenzo, who remained a private citizen, we shall return in time; it is Cosimo (1389–1464) with whom we are now concerned. Cosimo de' Medici was a man of great mental and practical ability: he had been educated as well as possible; he had a passion both for art and letters; he inherited his father's financial ability and generosity, while he added to these gifts a certain genius for the management of men. One of the first things that Cosimo did after his father's death was to begin the palace where we now are, rejecting a plan by Brunelleschi as too splendid, and choosing instead one by Michelozzo, the partner of Donatello, two artists who remained his personal friends through life. Cosimo selected this site, in what was then the Via Larga but is now the Via Cavour, partly because his father had once lived there, and partly because it was close to S. Lorenzo, which his father, with six other families, had begun to rebuild, a work he intended himself to carry on.
The palace was begun in 1430 abd was still in progress in 1433 when the Albizzi, who had always viewed the rise of the Medici family with apprehension and misgiving, and were now strengthened by the death of Niccolò da Uzzano, who, though powerful, had been a very cautious and temperate adviser, succeeded in getting a majority in the Signoria and passing a sentence of banishment on the whole Medici tribe as being too rich and ambitious to be good citizens of a simple and frugal Republic. Cosimo therefore, after some days of imprisonment in the tower of the Palazzo Vecchio, during which he expected execution at any moment, left Florence for Venice, taking his architect with him. In 1434, however, the Florentines, realizing that under the Albizzi they were losing their independence, and what was to be a democracy was become an oligarchy, revolted, and Cosimo was recalled, and, like his father, was elected gonfalonier. With this recall began his long supremacy; for he returned like a king and like a king remained, quickly establishing himself as the leading man in the city, the power behind the Signoria. Not only did he never lose that position, but he made it so naturally his own that when he died he was able to transmit it to his son.
Cosimo de' Medici was, I think, the wisest and best ruler that Florence ever had and ranks high among the rulers that any state ever had. But he changed the Florentines from an independent people to a dependent one. In his capacity of Father of his Country he saw to it that his children lost their proud spirit. He had to be absolute; and this end he achieved in many ways, but chiefly by his wealth, which made it possible to break the rich rebel and to enslave the poor. His greatest asset—next his wealth—was his knowledge of the Florentine character. To know anything of this capricious, fickle, turbulent folk even after the event was in itself a task of such magnitude that almost no one else had compassed it; but Cosimo did more, he knew what they were likely to do. By this knowledge, together with his riches, his craft, his tact, his business ramifications as an international banker, his open-handedness and air of personal simplicity, Cosimo made himself a power. For Florence could he not do enough. By inviting the Pope and the Greek Emperor to meet there he gave it great political importance, and incidentally brought about the New Learning. He established the Platonic Academy and formed the first public library in the west. He rebuilt and endowed the monastery of S. Marco. He built and rebuilt other churches. He gave Donatello a free hand in sculpture and Fra Lippo Lippi and Fra Angelico in painting. He distributed altogether in charity and churches four hundred thousand of those golden coins which were invented by Florence and named florins after her—a sum equal to a million pounds of to-day. In every direction one comes upon traces of his generosity and thoroughness. After his death it was decided that as Pater Patriae, or Father of his Country, he should be for ever known.
Cosimo died in 1464, leaving an invalid son, Piero, aged forty-eight, known for his almost continuous gout as Il Gottoso. Giovanni and Cosimo had had to work for their power; Piero stepped naturally into it, although almost immediately he had to deal with a plot—the first for thirty years—to ruin the Medici prestige, the leader of which was that Luca Pitti who began the Pitti palace in order to have a better house than the Medici. The plot failed, not a little owing to young Lorenzo de' Medici's address, and the remaining few years of Piero's life were tranquil. He was a quiet, kindly man with the traditional family love of the arts, and it was for him that Gozzoli worked. He died in 1469, leaving two sons, Lorenzo (1449–1492) and Giuliano (1453–1478).
Lorenzo had been brought up as the future leading citizen of Florence: he had every advantage of education and environment, and was rich in the aristocratic spirit which often blossoms most richly in the second or third generation of wealthy business families. Giovanni had been a banker before everything, Cosimo an administrator, Piero a faithful inheritor of his father's wishes; it was left for Lorenzo to be the first poet and natural prince of the Medici blood. Lorenzo continued to bank but mismanaged the work and lost heavily; while his poetical tendencies no doubt distracted his attention generally from affairs. Yet such was his sympathetic understanding and his native splendour and gift of leadership that he could not but be at the head of everything, the first to be consulted and ingratiated. Not only was he the first Medici poet but the first of the family to marry not for love but for policy, and that too was a sign of decadence.
Lorenzo came into power when only twenty, and at the age of forty-two he was dead, but in the interval, by his interest in every kind of intellectual and artistic activity, by his passion for the greatness and glory of Florence, he made for himself a name that must always connote liberality, splendour, and enlightenment. But it is beyond question that under Lorenzo the Florentines changed deeply and for the worse. The old thrift and simplicity gave way to extravagance and ostentation; the old faith gave way too, but that was not wholly the effect of Lorenzo's natural inclination towards Platonic philosophy, fostered by his tutor Marsilio Ficino and his friends Poliziano and Pico della Mirandola, but was due in no small measure also to the hostility of Pope Sixtus, which culminated in the Pazzi Conspiracy of 1478 and the murder of Giuliano. Looking at the history of Florence from our present vantage-point we can see that although under Lorenzo the Magnificent she was the centre of the world's culture and distinction, there was behind this dazzling front no seriousness of purpose. She was in short enjoying the fruits of her labours as though the time of rest had come; and this when strenuousness was more than ever important. Lorenzo carried on every good work of his father and grandfather (he spent £65,000 a year in books alone) and was as jealous of Florentine interests; but he was also "The Magnificent," and in that lay the peril. Florence could do with wealth and power, but magnificence went to her head.
Lorenzo died in 1492, leaving three sons, of whom the eldest, Piero (1471–1503), succeeded him. Never was such a decadence. In a moment the Medici prestige, which had been steadily growing under Cosimo, Piero, and Lorenzo until it was world famous, crumbled to dust. Piero was a coarse-minded, pleasure-loving youth—"The Headstrong" his father had called him—whose one idea of power was to be sensual and tyrannical; and the enemies of Florence and of Italy took advantage of this fact. Savonarola's sermons had paved the way from within too. In 1494 Charles VIII of France marched into Italy; Piero pulled himself together and visited the king to make terms for Florence, but made such terms that on returning to the city he found an order of banishment and obeyed it. On November 9th, 1494, he and his family were expelled, and the mob, forgetting so quickly all that they owed to the Medici who had gone before, rushed to this beautiful palace and looted it. The losses that art and learning sustained in a few hours can never be
