Early lifeEdit

Honore the first to the left with his siblings

Honoré was born on 10 November 1720

On 20 May 1732, he moved to Hôtel Matignon in Paris with his father and remained there, even after the proclamation in 1733 of him as Prince of Monaco. Antoine Grimaldi, le Chevalier de Grimaldi, acted as regent for the prince between 1732 and 1784, when Honoré chose to reside in Paris. This situation remained the same for half a century until Antoine's death in 1784, when Honoré III was already 64 years old. Although he was open to the revolutionary ideas of the time, he was imprisoned on 20 September 1793. At his liberation a year later, he was ruined, and his property under seal.


While in Paris, it was suggested that he marry Marie Louise de La Tour d'Auvergne, but the marriage never materialised. In 1751, he married Maria Caterina Brignole (d. 1813).

The couple had two children; Honoré IV, Prince of Monaco and Joseph Grimaldi (10 September 1763 – 28 June 1816) before divorcing in 1770, and Marie-Catherine married the Prince de Condé in 1798.
