Word Origin and History for have the courage of one's convictions
c.1300, from Old French corage (12c., Modern French courage) "heart, innermost feelings; temper," from Vulgar Latin *coraticum (source of Italian coraggio, Spanish coraje), from Latin cor "heart" (see heart) which remains a common metaphor for inner strength.
In Middle English, used broadly for "what is in one's mind or thoughts," hence "bravery," but also "wrath, pride, confidence, lustiness," or any sort of inclination. Replaced Old English ellen, which also meant "zeal, strength."
