[Illustration: Fig. 19.--Serf or Vassal of Tenth Century, from Miniatures in the "Dialogues of St. Gregory," Manuscript No. 9917 (Royal Library of Brussels).] As early as the commencement of the third royal dynasty we find in the rural districts, as well as in the towns, a great number of free men: and as the charters concerning the condition of lands and persons became more and more extended, the tyranny of the great was reduced, and servitude decreased. During the following centuries, the establishment of civic bodies and the springing up of the middle classes (Fig. 20) made the acquisition of liberty more easy and more general. Nevertheless, this liberty was rather theoretical than practical; for if the nobles granted it nominally, they gave it at the cost of excessive fines, and the community, which purchased at a high price the right of self-administration, did not get rid of any of the feudal charges imposed upon it.

They formed a sort of small state, almost independent for private affairs, subject to the absolute power of the King, and more or less tied by their customs or agreements with the local nobles. They held public assemblies and elected magistrates, whose powers embraced both the administration of civil and criminal justice, police, finance, and the militia. They generally had fixed and written laws. Protected by ramparts, each possessed a town-hall (_hôtel de ville_), a seal, a treasury, and a watch-tower, and it could arm a certain number of men, either for its own defence or for the service of the noble or sovereign under whom it held its rights.
