At the State Opening of the First Imperial Synkletos, Basileus Petros III was pleased to create, ennoble, and raise his beloved daughter, Princess Olympia to the dignity of Princess of Nivardom, settling upon her the existing city of Nivardom, "for her maintenance and that of her natural heirs, that, should she be so pleased, she may reside and govern there and direct and defend those parts, to hold to her and the natural heirs of her body, forever."
On the accession of Olympia as Basilinna, this dignity merged into the crown.
The Principality of Nivardom is located in Central Eura.
