Saxe

Saxony (a state of modern Germany, located in the east, far from historical Saxon lands); Saxony (a historical region and former duchy in north-central Germany)

From Middle French Saxe, an apparently semi-learned form which displaced Old French Saisunie, Sessoigne, etc., from Latin Saxōnia, perhaps after Medieval Latin Saxia or influenced by German Sachsen itself. Compare Middle French Saxone (“Saxony”).
