Background
Florestine married Count Wilhelm of Württemberg (later Wilhelm, 1st Duke of Urach), son of Duke Wilhelm of Württemberg and his morganatic wife Baroness Wilhelmine von Tunderfeldt-Rhodis, on 15 February 1863 in Monaco.
Florestine married Count Wilhelm of Württemberg (later Wilhelm, 1st Duke of Urach), son of Duke Wilhelm of Württemberg and his morganatic wife Baroness Wilhelmine von Tunderfeldt-Rhodis, on 15 February 1863 in Monaco.
Florestine, according to the rules governing succession to the throne of Monaco, was able to marry without relinquishing her rights. When her grandnephew Louis II, Prince of Monaco, ascended to the Monegasque throne, Florestine"s son Wilhelm claimed his rights for his succession to the princely throne of Monaco and the Grimaldi noble titles. However, France had undergone two wars against Germany and did not wish to see German princes ruling the Principality of Monaco.
Therefore, France reached an agreement with the principality allowing the illegitimate daughter of Louis II, Charlotte, to be his heir presumptive to the princely throne and Grimaldi noble titles.
