The political institutions of the Parlement (pronounce /paʀləmɑ̃/ in French) in ancien régime France developed out of the previous council of the king, the Conseil du roi or curia regis, and consequently had ancient and customary rights of consultation and deliberation. In the thirteenth century, judicial functions were added. The parlementarians were of the opinion that the parlement's role included active participation in the legislative process, which brought them into increasing conflict with evolving monarchic absolutism during the Ancien Régime, as the lit de justice evolved during the sixteenth century from a constitutional forum to a royal weapon, used to force registration of edicts.
