Under the
House of Capet of France, the monarchy was
feudal, and the younger sons and grandsons of kings did not have rights or precedence based on their royal descent. Feudal titles determined rank. Under
Philip Augustus, the
Duke of Burgundy, a
peer of France, could be reckoned to be mightier than the
Count of Dreux, a "
baron of the second rank", even though the latter was a paternal cousin of the king, while the former was only a distant
agnate. In the feudal era, the agnates of the king held no special status, because agnatic primogeniture had not yet received its sanction as the law governing the succession to the French throne. Following the
Valois succession, the agnates of the king, being "capable of the crown", rose in prominence. New peerages were created for the king's agnates, and for a long time this continued to be so, before the peerage was extended to non-royalty. Over time, the dignity of a peer, which was feudal in nature, and the dignity of a prince of the blood, which was dynastic in nature, clashed. Non-royal peers and princes of the blood who were peers constantly competed for precedence. As the royal line contracted, each prince of the blood gained greater prominence. Finally, in 1576, King
Henry III of France issued an
edict, to counter the growing power of the
House of Guise, which made the princes of the blood supreme over the peerage, and amongst themselves, the closer in the line of succession would outrank the more distant, without regard to the actual title that they held. ==As a rank==
