The cumulative effect of these conquests was to prompt the kings to appoint their younger sons to territories: the apanages or privileges. This policy would allow the kings to progressively impose royal authority on the provinces, since in practice, the apanages would return without difficulty, to the crown whether by inheritance or by confiscation. This happened for example, in Poitou, in 1271 and Anjou, in 1481. These were two provinces taken by conquest from the kings of England by Phillip Augustus and Louis VIII.

L’Époque contemporaine

The French title of this section has been retained in translation from the French Wikipedia page because the apparently corresponding term in English has not quite the same meaning. English-speaking historians, though they define it otherwise, in effect, regard the term 'contemporary history' as meaning 'within living memory'. French writers on the other hand, are inclined to open the period with the French Revolution.

Implementation of a new concept of national territory

The Revolution did away with the concept of ownership of political entities by individuals. France became one state rather than the aggregate of a mosaic of semi-states.
Suppression of the provinces and creation of the départements

As a means of loosening old ties of allegiance, and of rationalizing administration, the old divisions based on feudal ownership were replaced by départements of roughly uniform size and named after geographical features such as rivers. Even Paris was in the département of Seine. Nevertheless, in some cases such as Nord the modern département comprises broadly, the territory of one period of acquisition.
Reduction of enclaves

Several territories were foreign enclaves surrounded by the lands of the kingdom of France. The Convention nationale willed their merging into France, by treaty or regardless of the rights of the (mainly German) princely owners.
Some of these treaties were:
