In that year an important change was effected in the Constitution. The whole population of Florence consisted, on the one hand, of nobles or Grandi, as they were called in Tuscany, and on the other hand of working people. The latter, divided into traders and handicraftsmen, were distributed in guilds called Arti; and at that time there were seven Greater and five Lesser Arti, the most influential of all being the Guild of the Wool Merchants. These guilds had their halls for meeting, their colleges of chief officers, their heads, called Consoli or Priors, and their flags. In 1266 it was decided that the administration of the commonwealth should be placed simply and wholly in the hands of the Arti, and the Priors of these industrial companies became the lords or Signory of Florence. No inhabitant of the city who had not enrolled himself as a craftsman in one of the guilds could exercise any function of burghership. To be scioperato, or without industry, was to be without power, without rank or place of honour in the State. The revolution which placed the Arts at the head of the republic had the practical effect of excluding the Grandi altogether from the government. Violent efforts were made by these noble families, potent through their territorial possessions and foreign connections, and trained from boyhood in the use of arms, to recover the place from which the new laws thrust them: but their menacing attitude, instead of intimidating the burghers, roused their anger and drove them to the passing of still more stringent laws. In 1293, after the Ghibellines had been defeated in the great battle of Campaldino, a series of severe enactments, called the Ordinances of Justice, were decreed against the unruly Grandi. All civic rights were taken from them; the severest penalties were attached to their slightest infringement of municipal law; their titles to land were limited; the privilege of living within the city walls was allowed them only under galling restrictions; and, last not least, a supreme magistrate, named the Gonfalonier of Justice, was created for the special purpose of watching them and carrying out the penal code against them. Henceforward Florence was governed exclusively by merchants and artisans. The Grandi hastened to enrol themselves in the guilds, exchanging their former titles and dignities for the solid privilege of burghership. The exact parallel to this industrial constitution for a commonwealth, carrying on wars with emperors and princes, holding haughty captains in its pay, and dictating laws to subject cities, cannot, I think, be elsewhere found in history. It is as unique as the Florence of Dante and Giotto is unique. While the people was guarding itself thus stringently against the Grandi, a separate body was created for the special purpose of extirpating the Ghibellines. A permanent committee of vigilance, called the College or the Captains of the Guelf Party, was established. It was their function to administer the forfeited possessions of Ghibelline rebels, to hunt out suspected citizens, to prosecute them for Ghibellinism, to judge them, and to punish them as traitors to the commonwealth. This body, like a little State within the State, proved formidable to the republic itself through the unlimited and undefined sway it exercised over burghers whom it chose to tax with treason. In course of time it became the oligarchical element within the Florentine democracy, and threatened to change the free constitution of the city into a government conducted by a few powerful families.
There is no need to dwell in detail on the internal difficulties of Florence during the first half of the fourteenth century. Two main circumstances, however, require to be briefly noticed. These are (i) the contest of the Blacks and Whites, so famous through the part played in it by Dante; and (ii) the tyranny of the Duke of Athens, Walter de Brienne. The feuds of the Blacks and Whites broke up the city into factions, and produced such anarchy that at last it was found necessary to place the republic under the protection of foreign potentates. Charles of Valois was first chosen, and after him the Duke of Athens, who took up his residence in the city. Entrusted with dictatorial authority, he used his power to form a military despotism. Though his reign of violence lasted rather less than a year, it bore important fruits; for the tyrant, seeking to support himself upon the favour of the common people, gave political power to the Lesser Arts at the expense of the Greater, and confused the old State-system by enlarging the democracy. The net result of these events for Florence was, first, that the city became habituated to rancorous party-strife, involving exiles and proscriptions; and, secondly, that it lost its primitive social hierarchy of classes.

After the Guelfs had conquered the Ghibellines, and the people had absorbed the Grandi in their guilds, the next chapter in the troubled history of Florence was the division of the Popolo against itself. Civil strife now declared itself as a conflict between labour and capital. The members of the Lesser Arts, craftsmen who plied trades subordinate to those of the Greater Arts, rose up against their social and political superiors, demanding a larger share in the government, a more equal distribution of profits, higher wages, and privileges that should place them on an absolute equality with the wealthy merchants. It was in the year 1378 that the proletariate broke out into rebellion. Previous events had prepared the way for this revolt. First of all, the republic had been democratised through the destruction of the Grandi and through the popular policy pursued to gain his own ends by the Duke of Athens. Secondly, society had been shaken to its very foundation by the great plague of 1348. Both Boccaccio and Matteo Villani draw lively pictures of the relaxed morality and loss of order consequent upon this terrible disaster; nor had thirty years sufficed to restore their relative position to grades and ranks confounded by an overwhelming calamity. We may therefore reckon the great plague of 1348 among the causes which produced the anarchy of 1378. Rising in a mass to claim their privileges, the artisans ejected the Signory from the Public Palace, and for awhile Florence was at the mercy of the mob. It is worthy of notice that the Medici, whose name is scarcely known before this epoch, now came for one moment to the front. Salvestro de' Medici was Gonfalonier of Justice at the time when the tumult first broke out. He followed the faction of the handicraftsmen, and became the hero of the day. I cannot discover that he did more than extend a sort of passive protection to their cause. Yet there is no doubt that the attachment of the working classes to the House of Medici dates from this period. The rebellion of 1378 is known in Florentine history as the Tumult of the Ciompi. The name Ciompi strictly means the Wool-Carders. One set of operatives in the city, and that the largest, gave its title to the whole body of the labourers. For some months these craftsmen governed the republic, appointing their own Signory and passing laws in their own interest; but, as is usual, the proletariate found itself incapable of sustained government. The ambition and discontent of the Ciompi foamed themselves away, and industrious working men began to see that trade was languishing and credit on the wane. By their own act at last they restored the government to the Priors of the Greater Arti. Still the movement had not been without grave consequences. It completed the levelling of classes, which had been steadily advancing from the first in Florence. After the Ciompi riot there was no longer not only any distinction between noble and burgher, but the distinction between greater and lesser guilds was practically swept away. The classes, parties, and degrees in the republic were so broken up, ground down, and mingled, that thenceforth the true source of power in the State was wealth combined with personal ability. In other words, the proper political conditions had been formed for unscrupulous adventurers. Florence had become a democracy without social organisation, which might fall a prey to oligarchs or despots. What remained of deeply rooted feuds or factions—animosities against the Grandi, hatred for the Ghibellines, jealousy of labour and capital—offered so many points of leverage for stirring the passions of the people and for covering personal ambition with a cloak of public zeal. The time was come for the Albizzi to attempt an oligarchy, and for the Medici to begin the enslavement of the State.

The Constitution of Florence offered many points of weakness to the attacks of such intriguers. In the first place it was in its origin not a political but an industrial organisation—a simple group of guilds invested with the sovereign authority. Its two most powerful engines, the Gonfalonier of Justice and the Guelf College, had been formed, not with a view to the preservation of the government, but with the purpose of quelling the nobles and excluding a detested faction. It had no permanent head, like the Doge of Venice; no fixed senate like the Venetian Grand Council; its chief magistrates, the Signory, were elected for short periods of two months, and their mode of election was open to the gravest criticism. Supposed to be chosen by lot, they were really selected from lists drawn up by the factions in power from time to time. These factions contrived to exclude the names of all but their adherents from the bags, or borse, in which the burghers eligible for election had to be inscribed. Furthermore, it was not possible for this shifting Signory to conduct affairs requiring sustained effort and secret deliberation; therefore recourse was being continually had to dictatorial Commissions. The people, summoned in parliament upon the Great Square, were asked to confer plenipotentiary authority upon a committee called Balia, who proceeded to do what they chose in the State, and who retained power after the emergency for which they were created passed away. The same instability in the supreme magistracy led to the appointment of special commissioners for war, and special councils, or Pratiche, for the management of each department. Such supplementary commissions not only proved the weakness of the central authority, but they were always liable to be made the instruments of party warfare. The Guelf College was another and a different source of danger to the State. Not acting under the control of the Signory, but using its own initiative, this powerful body could proscribe and punish burghers on the mere suspicion of Ghibellinism. Though the Ghibelline faction had become an empty name, the Guelf College excluded from the franchise all and every whom they chose on any pretext to admonish. Under this mild phrase, to admonish, was concealed a cruel exercise of tyranny—it meant to warn a man that he was suspected of treason, and that he had better relinquish the exercise of his burghership. By free use of this engine of Admonition, the Guelf College rendered their enemies voiceless in the State, and were able to pack the Signory and the councils with their own creatures. Another important defect in the Florentine Constitution was the method of imposing taxes. This was done by no regular system. The party in power made what estimate it chose of a man's capacity to bear taxation, and called upon him for extraordinary loans. In this way citizens were frequently driven into bankruptcy and exile; and since to be a debtor to the State deprived a burgher of his civic rights, severe taxation was one of the best ways of silencing and neutralising a dissentient.
I have enumerated these several causes of weakness in the Florentine State-system, partly because they show how irregularly the Constitution had been formed by the patching and extension of a simple industrial machine to suit the needs of a great commonwealth; partly because it was through these defects that the democracy merged gradually into a despotism. The art of the Medici consisted in a scientific comprehension of these very imperfections, a methodic use of them for their own purposes, and a steady opposition to any attempts made to substitute a stricter system. The Florentines had determined to be an industrial community, governing themselves on the co-operative principle, dividing profits, sharing losses, and exposing their magistrates to rigid scrutiny. All this in theory was excellent. Had they remained an unambitious and peaceful commonwealth, engaged in the wool and silk trade, it might have answered. Modern Europe might have admired the model of a communistic and commercial democracy. But when they engaged in aggressive wars, and sought to enslave sister-cities like Pisa and Lucca, it was soon found that their simple trading constitution would not serve. They had to piece it out with subordinate machinery, cumbrous, difficult to manage, ill-adapted to the original structure. Each limb of this subordinate machinery, moreover, was a point d'appui for insidious and self-seeking party leaders.
Florence, in the middle of the fourteenth century, was a vast beehive of industry. Distinctions of rank among burghers, qualified to vote and hold office, were theoretically unknown. Highly educated men, of more than princely wealth, spent their time in shops and counting-houses, and trained their sons to follow trades. Military service at this period was abandoned by the citizens; they preferred to pay mercenary troops for the conduct of their wars. Nor was there, as in Venice, any outlet for their energies upon the seas. Florence had no navy, no great port—she only kept a small fleet for the protection of her commerce. Thus the vigour of the commonwealth was concentrated on itself; while the influence of the citizens, through their affiliated trading-houses, correspondents, and agents, extended like a network over Europe. In a community of this kind it was natural that wealth—rank and titles being absent—should alone confer distinction. Accordingly we find that out of the very bosom of the people a new plutocratic aristocracy begins to rise. The Grandi are no more; but certain families achieve distinction by their riches, their numbers, their high spirit, and their ancient place of honour in the State. These nobles of the purse obtained the name of Popolani Nobili; and it was they who now began to play at high stakes for the supreme power. In all the subsequent vicissitudes of Florence every change takes place by intrigue and by clever manipulation of the political machine. Recourse is rarely had to violence of any kind, and the leaders of revolutions are men of the yard-measure, never of the sword. The despotism to which the republic eventually succumbed was no less commercial than the democracy had been. Florence in the days of her slavery remained a Popolo.

The opening of the second half of the fourteenth century had been signalised by the feuds of two great houses, both risen from the people. These were the Albizzi and the Ricci. At this epoch there had been a formal closing of the lists of burghers;—henceforth no new families who might settle in the city could claim the franchise, vote in the assemblies, or hold magistracies. The Guelf College used their old engine of admonition to persecute novi homines, whom they dreaded as opponents. At the head of this formidable organisation the Albizzi placed themselves, and worked it with such skill that they succeeded in driving the Ricci out of all participation in the government. The tumult of the Ciompi formed but an episode in their career toward oligarchy; indeed, that revolution only rendered the political material of the Florentine republic more plastic in the hands of intriguers, by removing the last vestiges of class distinctions and by confusing the old parties of the State.
