Little White - Amadeus IX

Amadeus IX ruled Savoy under the effective regency of his wife Yolande of France — sister of Louis XI — while he suffered from severe epilepsy that rendered him largely incapable of governance. The "Little White" denomination was a small billon or silver fraction circulating across the Alpine territories at a moment when Savoyard monetary policy was increasingly dictated by French dynastic interests rather than ducal prerogative.

Amadeus was beatified in 1677, making him one of the very few ruling princes of his century to achieve that distinction.
