But the most important point to be noted at this juncture is that the conquest of fresh territory, although become an absolute necessity to the Republic, now began to be a serious danger and the source of future calamities. During the Middle Ages the Italian Commune had been a fertile cause of progress; but as its possessions outside the walls began to increase, it proved wholly powerless to convert the free city into what we call a State without working radical changes in its constitution. In fact, even in Florence, the most democratic of our communes, citizens were only to be found within the circuit of the walls. Laws were framed to ameliorate the condition of the territory outside and to abolish serfdom there, but no one contemplated endowing inhabitants of the _contado_ with political rights. The title of citizens always remained, as it were, a privilege only granted to a minority, even of dwellers within the walls, and was never extended to the people at large. Whenever a new city was conquered and subjected to the Republic, it was governed more or less harshly; allowed to retain more or fewer local privileges; sometimes even permitted to retain a republican form of government, subject to the authority of a Podestà, captain, or commissary, and paying the taxes imposed by them; but its inhabitants never enjoyed the freedom of the City, nor were their representatives by any chance admitted to the councils or political offices of Florence. Accordingly, as the State became enlarged by fresh conquests, the cluster of citizens monopolising the government, and already very limited in number, sank to a still smaller minority compared with the ever-increasing population subject to their rule. Similarly to all other republicans of the Middle Ages, the Florentines were altogether unable to conceive the idea of a State governed with a view to the general welfare. On the contrary, the prosperity and grandeur of Florence formed the one object and aim to which every other consideration had to be subservient. Nor had the lower classes and populace, who were always clamouring for increased freedom, any different or wider views on the subject. Their ideas, indeed, being restricted in a narrower circle, were even more prejudiced, as their passions were blinder. Consequently it was considered at that time a greater calamity to be subjugated by a fellow republic than by a monarchy; inasmuch as princes brought their tyranny to bear equally on all alike, and thus, at any rate as regarded politics, the chief majority of the conquered suffered less injury. When Florence, however, by achieving the long-desired conquest of Pisa, at last became mistress of the sea, and witnessed the rapid increase of her commerce, she discovered that the annexation of a great and powerful republic, full of life and strength and possessed of so large a trade, brought her none of the advantages which might have ensued from a union of a freer
