Now it so happened, as we shall see in the following chapter, that the commerce of the middle ages stimulated the growth of important trading towns in Italy, in Germany, and in the Netherlands. These towns, in one way or another, managed to secure a large measure of self-government, so that by the year 1500 they had become somewhat similar to the city- states of antiquity. In Germany, though they still maintained their local self-government, they were loosely attached to the Holy Roman Empire and were overshadowed in political influence by other states. In the case of Italy and of the Netherlands, however, it is impossible to understand the politics of those countries in the sixteenth century without paying some attention to city-states, which played leading rôles in both. [Sidenote: Italy in 1500 neither a National Monarchy not Attached to the Holy Roman Empire] In the Italy of the year 1500 there was not even the semblance of national political unity. Despite the ardent longings of many Italian patriots [Footnote: Of such patriots was Machiavelli (see below, p. 194). Machiavelli wrote in _The Prince:_ "Our country, left almost without life, still waits to know who it is that is to heal her bruises, to put an end to the devastation and plunder of Lombardy and to the exactions and imposts of Naples and Tuscany, and to stanch those wounds of hers which long neglect has changed into running sores. We see how she prays God to send some one to rescue her from these barbarous cruelties and oppressions. We see too how ready and eager she is to follow any standard, were there only some one to raise it."], and the rise of a common language, which, under such masters as Dante and Petrarch, had become a great medium for literary expression, the people of the peninsula had not built up a national monarchy like those of western Europe nor had they even preserved the form of allegiance to the Holy Roman Empire. This was due to several significant events of earlier times. In the first place, the attempt of the medieval German emperors to gain control of Italy not only had signally failed but had left behind two contending factions throughout the whole country,--one, the Ghibellines, supporting the doctrine of maintaining the traditional connection with the Germanies; the other, the Guelphs, rejecting that doctrine. In the second place, the pope, who exercised extensive political as well as religious power, felt that his ecclesiastical influence would be seriously impaired by the creation of political unity in the country; a strong lay monarch with a solid Italy behind him would in time reduce the sovereign pontiff to a subservient position and diminish the prestige which the head of the church enjoyed in foreign lands; therefore the popes participated actively in the game of Italian politics, always endeavoring to prevent any one state from becoming too powerful. Thirdly, the comparatively early commercial
