Antoine, who died in 1731, was the last direct male of the house. He left a daughter, Louise Hippolyte, who married Jacques François de Matignon, Comte de Torrigny. She survived her father but eleven months. Her son Honoré III. (1731-1795) lived at the time of the outbreak of the French Revolution. The new ideas excited effervescence in little Monaco, Roquebrune, and Mentone, which belonged at the time to the principality, and they demanded elective councils. Honoré was compelled to yield, whereupon the Councils suppressed all feudal rights. Then, when he was frightened and ran away, the three towns declared the House of Grimaldi deposed. Nice had been united to France, and Monaco demanded the same favour, which was granted February 14th, 1793. Honoré was arrested on September 28th, in the same year, and detained till Thermidor 9th. He died in 1795. By the treaty of Paris, 1814, Monaco was restored to Honoré IV., his son, but on the return of Napoleon from Elba, the principality was occupied by an English force. By the treaty of November 20th, 1815, it was transferred to Sardinia; but this lasted only till 1816, when Honoré V. regained his principality. His son Florestan I. (1841-56) abolished monopoly in bread, allowed free trade, and founded a college at Mentone. The revolution of 1848 was disastrous to the Prince. Mentone and Roquebrune severed their connexion with Monaco and were annexed to Sardinia. Charles III. (1856-89) succeeded his father, Florestan. He it was who conceived the idea of repairing his losses by the establishment of gaming tables at Monaco.

The princes had coined gold, silver, and copper money from 1505, with the legend, “Christus regnat, Christus imperat, Christus vincit.” This legend became inappropriate thenceforth, in Monaco.
In 1856 Charles III. started the gambling tables in a building adjoining the palace, afterwards occupied by the guard of honour. But the venture was not a success. Monaco was out of the way, hardly accessible from the land, where the Corniche Road ran high above, on the summit of the cliffs by La Turbie, so that it could be reached conveniently only by sea.
The gambling concession passed through various hands, till, owing to the closing of the Casino at Homburg, M. Blanc thought of Monaco. In 1863 he went there, on March 31st, entered the bureau of the then concessioners, Lefebre and Co., and said, “You want to sell this affair; I am disposed to take it. Reflect. I shall return here at 3.30 p.m. I leave at 4 p.m. by the steamboat, and I want to have this matter settled before I go back to Nice.” The company sold it to Blanc for 1,700,000 francs.
