From the time of Charlemagne, the people of the ancient Menapia, now become a prosperous commonwealth, formed political associations to raise a barrier against the despotic violence of the Franks. These associations were called Gilden, and in the Latin of the times Gildonia. They comprised, besides their covenants for mutual protection, an obligation which bound every member to give succor to any other, in cases of illness, conflagration, or shipwreck. But the growing force of these social compacts alarmed the quick-sighted despotism of Charlemagne, and they were, consequently, prohibited both by him and his successors. To give a notion of the importance of this prohibition to the whole of Europe, it is only necessary to state that the most ancient corporations (all which had preceded and engendered the most valuable municipal rights) were nothing more than gilden. Thus, to draw an example from Great Britain, the corporative charter of Berwick still bears the title of Charta Gildoniæ. But the ban of the sovereigns was without efficacy, when opposed to the popular will. The gilden stood their ground, and within a century after the death of Charlemagne, all Flanders was covered with corporate towns. This popular opposition took, however, another form in the northern parts of the country, which still bore the common name of Friesland; for there it was not merely local but national. The Frisons succeeded in obtaining the sanction of the monarch to consecrate, as it were, those rights which were established under the ancient forms of government. The fact is undoubted; but the means which they employed are uncertain. It appears most probable that this great privilege was the price of their military services; for they held a high place in the victorious armies of Charlemagne; and Turpin, the old French romancer, alluding to the popular traditions of his time, represents the warriors of Friesland as endowed with the most heroic valor.
