Florestan received only a small income from his family, so, as it turned out, his marriage to an
upper-bourgeois family member of the
province of Champagne was, in fact, "financially favorable."
The marriage produced the following:

Reign

Florestan was ill-prepared to assume the role of Sovereign Prince.
Indeed, the British historian H. Pemberton wrote that, upon accession to the throne, Florestan was "a man utterly unsuited for the task before him."
He had been an

At the time Monaco was surrounded by the
Sardinian controlled County of Nice.
As unprepared as Florestan was for the affairs of the Principality, his ascendance to power upon the death of his brother was largely welcomed by the populace. "He was given a particularly warm reception by the people of Menton," wrote Saige in French. Saige attributed the cause for this to the relief widely felt at having a prince who was not invisible to the public; unlike Honoré V, Florestan went out in public. He even established a school in Menton, albeit an expensive one from which the princely couple attempted to meet local demands for democratic reforms and offered two constitutions to the local population, but these were rejected, particularly by the people of Menton, who were offered something better by King
