The county of Perche was a medieval county lying between Normandy and Maine.
It was held by a continuous line of counts until 1226. One of these, Geoffroy III, would have been a leader of the Fourth Crusade had he not died before the assembled forces could depart. The county then became a possession of the crown, which removed part of it to create the county of Alençon.
After 1325, both counties were generally held by a member or members of a cadet line of the House of Valois. Upon the death without children of the last duke of Alençon in 1525, it returned to the crown, and was granted only sporadically thereafter.
Lords of Mortagne, lords of Nogent-le-Rotrou and viscounts of Châteaudun
The lords of Perche were originally titled lords of Mortagne-au-Perche, until Rotrou III adopted the style of count of Perche in 1126, thus uniting the lordship of Mortagne-au-Perche, the viscountcy of Châteaudun and the lordship of Nogent-le-Rotrou in the countship of Perche and Montagne.
