We have been opposing cities to nations; but it is easier to define a city than to define a nation. I think we may say, at least for our purpose, that the ideal nation is found when all the speakers of the same tongue on a continuous territory are united into a single political whole, which includes no speakers of other tongues. The nation in short should have unity of speech and unity of government. It would be hard to find a nation which exactly answers this definition, but the nearer a political body answers to it, the nearer surely does it come to the highest type of a nation. I think that, when we find anything else, when we find men of several tongues under the same government or men of the same tongue under several governments, we instinctively ask the reason. The reason may be a good one or it may not; but we cannot help asking the reason; the thing is, at the first look of it, an anomaly. Now free cities, with all their merits, are the greatest of all legitimate hindrances to national unity. I say of legitimate hindrances, of hindrances which come of themselves and which have something to be said for them, as distinguished from hindrances caused by external and unrighteous force. Italian unity was impossible as long as Milan and Venice were kept apart from the Italian body by the brute force of the House of Austria; but Italian unity was no less impossible in the days when Milan and Venice--Milan for a moment, Venice for ages--played a part in the affairs of the world as independent commonwealths. Italy, the land of free cities, has, largely because it had been the land of free cities, been of all the lands of Europe that which most thoroughly split asunder, that which most thoroughly became, in the well-known words of her enemy, a mere geographical expression. Germany, in her most divided days, was still far from being so utterly divided as Italy. Save during the few years of French ascendency, her princes and cities always kept up some kind of mutual relations towards one another. Germany always had a national Diet; Italy had none.
