It may be observed, that provinces amid the vicissitudes to which they are subject, pass from order into confusion, and afterward recur to a state of order again; for the nature of mundane affairs not allowing them to continue in an even course, when they have arrived at their greatest perfection, they soon begin to decline. In the same manner, having been reduced by disorder, and sunk to their utmost state of depression, unable to descend lower, they, of necessity, reascend; and thus from good they gradually decline to evil, and from evil again return to good. The reason is, that valor produces peace; peace, repose; repose, disorder; disorder, ruin; so from disorder order springs; from order virtue, and from this, glory and good fortune.
Hence, wise men have observed, that the age of literary excellence is subsequent to that of distinction in arms; and that in cities and provinces, great warriors are produced before philosophers. Arms having secured victory, and victory peace, the buoyant vigor of the martial mind cannot be enfeebled by a more excusable indulgence than that of letters; nor can indolence, with any greater or more dangerous deceit, enter a well regulated community. Cato was aware of this when the philosophers, Diogenes and Carneades, were sent ambassadors to the senate by the Athenians; for perceiving with what earnest admiration the Roman youth began to follow them, and knowing the evils that might result to his country from this specious idleness, he enacted that no philosopher should be allowed to enter Rome. Provinces by this means sink to ruin, from which, men's sufferings having made them wiser, they again recur to order, if they be not overwhelmed by some extraordinary force. These causes made Italy, first under the ancient Tuscans, and afterward under the Romans, by turns happy and unhappy;and although nothing has subsequently arisen from the ruins of Rome at all corresponding to her ancient greatness (which under a well-organized monarchy might have been gloriously effected), still there was so much bravery and intelligence in some of the new cities and governments that afterward sprang up, that although none ever acquired dominion over the rest, they were, nevertheless, so balanced and regulated among themselves, as to enable them to live in freedom, and defend their country from the barbarians.
Among these governments, the Florentines, although they possessed a smaller extent of territory, were not inferior to any in power and authority; for being situated in the middle of Italy, wealthy, and prepared for action, they either defended themselves against such as thought proper to assail them, or decided victory in favor of those to whom they became allies. From the valor, therefore, of these new governments, if no seasons occurred of long-continued peace, neither were any exposed to the calamities of war; for that cannot be called peace in which states frequently assail each other with arms, nor can those be considered wars in which no men are slain, cities plundered, or sovereignties overthrown; for the practice of arms fell into such a state of decay, that wars were commenced without fear, continued without danger, and concluded without loss. Thus the military energy which is in other countries exhausted by a long peace, was wasted in Italy by the contemptible manner in which hostilities were carried on, as will be clearly seen in the events to be described from 1434 to 1494, from which it will appear how the barbarians were again admitted into Italy, and she again sunk under subjection to them. Although the transactions of our princes at home and abroad will not be viewed with admiration of their virtue and greatness like those of the ancients, perhaps they may on other accounts be regarded with no less interest, seeing what masses of high spirited people were kept in restraint by such weak and disorderly forces. And if, in detailing the events which took place in this wasted world, we shall not have to record the bravery of the soldier, the prudence of the general, or the patriotism of the citizen, it will be seen with what artifice, deceit, and cunning, princes, warriors, and leaders of republics conducted themselves, to support a reputation they never deserved. This, perhaps, will not be less useful than a knowledge of ancient history;for, if the latter excites the liberal mind to imitation, the former will show what ought to be avoided and decried.
Italy was reduced to such a condition by her rulers, that when, by consent of her princes, peace was restored, it was soon disturbed by those who retained their armies, so that glory was not gained by war nor repose by peace. Thus when the league and the duke of Milan agreed to lay aside their arms in 1433, the soldiers, resolved upon war, directed their efforts against the church. There were at this time two factions or armed parties in Italy, the Sforzesca and the Braccesca.
