text: Despite its lack of continuous occupancy, by the final quarter of the 18th century the palace was once again a "splendid place" (Illustration 12). However revolution was afoot, and in the late 1780s Honoré III had to make concessions to his people who had caught the revolutionary ideas from their French neighbours. This was only the beginning of the Grimaldi's problems. In 1793 the leaders of the French Revolution annexed Monaco. The prince was imprisoned in France and his property and estates, including the palace, were forfeited to France.
  The palace was looted by the prince's subjects, and what remained of the furnishings and art collection was auctioned by the French government. Further changes were heaped on both the country and palace. Monaco was renamed Fort d'Hercule and became a canton of France while the palace became a military hospital and poorhouse. In Paris, the prince's daughter-in-law Francoise-Thérèse de Choiseul-Stainville (1766–1794) was executed, one of the last to be guillotined during the Reign of Terror. Honoré III died in 1795 in Paris, where he had spent most of his life, without regaining his throne.

  Regaining the palace
  Honoré III was succeeded by his son Honoré IV (1758–1819) whose marriage to Louise d'Aumont Mazarin had done so much to restore the Grimaldi fortunes. Much of this fortune had been depleted by the hardships of the revolution. On 17 June 1814 under the Treaty of Paris, the Principality of Monaco was restored to Honoré IV.
