Roger III of Foix

Roger III (died 1148) was Count of Foix from 1124, the son of Roger II. In 1117 he married Jimena of Barcelona, granddaughter of the Cid. He backed Bernard Aton IV Trencavel's claims to the viscounty of Carcassonne against Raymond Berengar III of Barcelona, and took Bernard Aton's children under his protection after his death in 1129.

In 1134 he helped his suzerain Alphonse Jourdain of Toulouse broker peace between the kings of Castile and Aragon. In the Baussenque wars over Provence, he remained loyal to Toulouse, unlike many other lords.
