[1] Prince Florestan, age 29, married Maria Caroline Gibert de Lametz in Commercy on 27 November 1816.

[3] The real power during his reign lay in the hands of his wife, Princess Caroline, who possessed great intelligence[1] and "excelled at social skills.

"[3] According to the historian Gustave Saige, Princess Caroline's intelligence was required to figure out the affairs of state, which Honoré V had handled absolutely by himself, not trusting anyone to advise or assist him.

[1] For some time, she was able, by tax reform,[1] to alleviate the difficult economic situation stemming from the Congress of Vienna assigning Monaco as a protectorate of the Kingdom of Sardinia rather than France.

Despite his good intentions, by the time of Florestan's death in Paris in 1856, Monaco was a country divided with few prospects for financial prosperity.
