Originally, there were thirteen peerages in France: six ecclesiastical and seven lay. Since then the number of peerages all but exploded which generally decreased the value of a peerage - but not making it completely worthless.
Since the end of the 13th century the peers took on the role of royal officer; as such it is not a title of nobility. It soon became evident to the kings that they could tie the most important nobles to themselves by granting them peerages. Consequently, from the 16th century the granting of peerages escalated. In the ancien regime the rights that came with a peerage were primarily attached to honorific functions; it was different in England. A peer enjoyed certain privileges. These included the right to a seat in the Parlement of Paris as well as the right to be judges by their peers - meaning by aristocrats who were also peers.
The dignity attached to each peerage was dependent on the age of that peerage's creation. Note that in the following list I have only included the peerages that were still in use by the time Louis XIV ascended the throne. The year in italic is the year it was founded.
The Ecclesiastical Peerages:
Archbishop-Duke of Reims
Bishop-Duke of Langres
Bishop-Duke of Laon
Bishop-Count of Beauvais
Bishop-Count of Châlons
Bishop-Count of Noyon
The Archbishop of Paris was per definition also given the title of Duc de Saint-Cloud but was not an original peer.
The Original Lay Peerages:
Duc de Bourgogne
Duc de Normandie
Duc d'Aquitaine (later renamed to Duc de Guyenne)
Comte de Flandre
Comte de Champagne
Comte de Toulouse
