Louis, Count of Évreux

Louis of Évreux (1276–1319), son of King Philip III of France, was a half-brother of Philip IV, who in 1298 granted him the county of Évreux. He fought in Flanders and distinguished himself at Mons-en-Pévèle in 1304, but won greater note as a diplomat, negotiating the treaties of Paris (1303) and Athis-sur-Orge (1305).

In 1316 he backed his nephew Philip V's regency, after which Évreux was raised into the peerage. By Margaret of Artois he fathered Philip III of Navarre and Joan, and he died at Longpont Abbey.
