Efforts towards National Unity
While the individual cantons were thus irremediably declining, the sense of unity was at the same time powerfully stirring in the nation and seeking in various ways to take shape and hold. That combination of the whole Celtic nobility in contradistinction to the individual canton-unions, while disturbing the existing order of things, awakened and fostered the conception of the collective unity of the nation. The attacks directed against the nation from without, and the continued diminution of its territory in war with its neighbours, operated in the same direction. Like the Greeks in their wars with the Persians, and the Italians in their wars with the Celts, the Transalpine Gauls seem to have become conscious of the existence and the power of their national unity in the wars against Rome.
Amidst the dissensions of rival clans and all their feudal quarrelling there might still be heard the voices of those who were ready to purchase the independence of the nation at the cost of the independence of the several cantons, and even at that of the seignorial rights of the knights. The thorough popularity of the opposition to a foreign yoke was shown by the wars of Caesar, with reference to whom the Celtic patriot party occupied a position entirely similar to that of the German patriots towards Napoleon; its extent and organization are attested, among other things, by the telegraphic rapidity with which news was communicated from one point to another.
