**Honoré III** (Honoré Louis Antoine Lucien Hercule; born 25th July 1642) is the reigning *Prince de Monaco*, succeeding his grandfather Honoré II upon his death in January 1662. While reigning as prince, Honoré resides almost exclusively at the court of Vasttaire, where he is known as the ***Duc de Valentinois***, a title from within the peerage of Vasttaire. At the imperial court, he quickly became well-established, being elevated to the prestigious role of *Grand Maître de l'Empire*, one of the great officers of the crown, giving him preeminence within the household of the Emperor, Charles XIX.

## Early Life and Origins

### Birth and Family

The House of Grimaldi is an old and proud one, dating back to c. 1160, when it was founded by a Genoese patrician named Grimaldo Canella, who served several terms as consul of the city of Genoa. The family became notable for several maritime expeditions, and quickly became one of the most powerful families in Genoa. Francesco Grimaldi, a scion of the family, led an expedition and captured the Rock of Monaco on the night of January 8th, 1297, declaring himself Lord of Monaco. In 1419, the Grimaldi formally purchased Monaco, ending any ownership dispute and making them formally sovereigns of the small territory.

Honoré Louis Antoine Lucien Hercule de Grimaldi was born on July 25th, 1642 at the Prince's Palace, in Monaco. He was the eldest child of Prince Hercule, Marquis des Baux (heir to the Monegasque throne) and his wife, Marie Aurélie Spinole, a member of a notable noble house from Genoa. At the time of his birth, his grandfather, Honoré II, was the reigning prince. As a member of the ruling house of Grimaldi, he was entitled to the style of *Serene Highness*, and was created Comte de Carladès by his grandfather.
