older sister of the Western Roman Emperor Valentinian III
417 CE
to 454 CE
Justa Grata Honoria, commonly referred to during her lifetime as Honoria, is the older sister of the Western Roman Emperor Valentinian III — famous for her plea to Attila the Hun which leads to his claim for half of the western Empire.
Coins attest that she was granted the title of Augusta not long after the ascension of her brother in 426.
