In Roman times Conflent was a pagus (district) dependent on Ruscino, the nucleus of later Roussillon.
[2] Until 870 Conflent was also attached to the counties of Urgell and Cerdanya, but in that year Charles the Bald granted it to Miro the Elder, who already governed the Capcir and Fenouilledès.
Under Wilfred's heirs the nominal authority of the Carolingian monarch was disregarded and Conflent was ruled as a family possession.
Under Wilfred II, however, it achieved prominence over Cerdagne when he built a palace at Corneilla-de-Conflent and resided there frequently.
Conflent remained as a recognisable feudal unit as late as c.1200, when it was one of three counties (along with Cerdanya and Roussillon) whose charters were gathered together in the great cartulary called the Liber feudorum Ceritaniae.
