Niccolò Machiavelli

“ Being placed in a marshy and unwholesome situation, it became healthy only by the number of industrious individuals who were drawn together. Pisa, too, on account of its unwholesome air, was never filled with inhabitants, till the Saracens, having destroyed Genoa and rendered her rivers unnavigable, caused the Genoese to migrate thither in vast numbers, and thus render her populous and powerful. Where the use of colonies is not adopted, conquered countries are held with great difficulty; districts once uninhabited still remain so, and those which populate quickly are not relieved. ”

“ And afterward, when the Romans, having conquered the Carthaginians, rendered Italy secure from foreign invasion, these buildings would greatly increase; for men never endure inconveniences unless some powerful necessity compels them. Thus, although the fear of war induces a willingness to occupy places strong and difficult of access, as soon as the cause of alarm is removed, men gladly resort to more convenient and easily attainable localities. ”

“ The cavalier, seeing the beauty of the girl, which was very uncommon, and considering the nobility of her blood, and her portion not being inferior to that of the lady whom he had chosen, became inflamed with such an ardent desire to possess her, that, not thinking of the promise given, or the injury he committed in breaking it, or of the evils which his breach of faith might bring upon himself, said, "Since you have reserved her for me, I should be very ungrateful indeed to refuse her, being yet at liberty to choose;" ”

“ Neither can a province be wholly occupied and preserve a proper distribution of its inhabitants without this regulation; for all districts are not equally healthy, and hence some will abound to overflowing, while others are void ”

“ Therefore, first by Sylla, and afterward by the three Roman citizens, who, having avenged the death of Cæsar, divided the empire among themselves, colonies were sent to Fiesole, which, either in part or in whole, fixed their habitations in the plain, near to the then rising town. By this increase, the place became so filled with dwellings, that it might with propriety be enumerated among the cities of Italy. ”

“ The custom of ancient republics to plant colonies, and the advantage of it—Increased population tends to make countries more healthy—Origin of Florence—Aggrandizement of Florence—Origin of the name of Florence—Destruction of Florence by Totila—The Florentines take Fiesole—The first division in Florence, and the cause of it—Buondelmonti—Buondelmonti slain—Guelphs and Ghibellines in Florence—Guelphic families—Ghibelline families—The two factions come to terms. ”

“ And, as nature cannot repair this disorder, it is necessary that industry should effect it, for unhealthy localities become wholesome when a numerous population is brought into them. With cultivation the earth becomes fruitful, and the air is purified with fires—remedies which nature cannot provide. ”

“ This murder divided the whole city; one party espousing the cause of the Buondelmonti, the other that of the Uberti; and as these families possessed men and means of defense, they contended with each other for many years, without one being able to destroy the other.
Florence continued in these troubles till the time of Frederick II., who, being king of Naples, endeavored to strengthen himself against the church; and, to give greater stability to his power in Tuscany, favored the Uberti and their followers, who, with his assistance, expelled the Buondelmonti ”

“ This may easily be done, by sending people to reside in recently acquired or uninhabited countries. Besides causing the establishment of new cities, these removals render a conquered country more secure, and keep the inhabitants of a province properly distributed. ”
