The History Royalty in Monaco

There are many books written about the long and exciting history of Monaco and the Grimaldi Family. Below, you will get a condensed version of this history.

From Monaco’s origins to the 13th century

From the earliest prehistoric times and Antiquity, the Rock of Monaco and its natural harbour served as a refuge for primitive populations, then navigators who had sailed from the East. It was in the 6th century BC that a Ligurian tribe which had settled in the region is believed to have given Monaco its name.

After the Phœnicians, from the 2nd century BC to the 5th century AD, the Romans moved into the region. They used Monaco’s waterfront, which took the name  of “Portus Herculis Monoeci” (Port d’Hercule).

From the early 6th century to the end of the 10th century, the region suffered many invasions. It wasn’t until the year 975 that the Count of Provence succeeded in getting rid of the Saracens, thus marking the start of a new era.

In 1162, Genoa’s authority over the Ligurian coast was recognised by the Emperor Frédéric I Barberousse, from Porto Venere as far as Monaco. In 1191, Emperor Henri VI finally conceded the Rock of Monaco to Genoa, together with its port and adjacent lands. The Genoese installed a colony on the Rock and built a fort (1215), which became the frontier-post west of the Republic.

In 1270, a civil war in Genoa opposed the Guelfes, supporters of the Pope, and the Gibelins, supporters of the Germanic Roman Emperor. Following a victory won by the Gibelins, many Guelfe families were banished into exile, including that of the Grimaldis.

By persevering, this powerful family of Genoese patricians outmatched the ruses of History and settled on the Rock of Monaco at the beginning of the Middle Ages. In response to the exile imposed on the Guelfes, the fortress of Monaco was taken by surprise on 8 January 1297 by a band of them led by François Grimaldi, nicknamed “Malizia”.

From the 13th to the 19th century

Charles Grimaldi, leader of the Guelfes, took possession of the Rock on 12 September 1331, but only assumed the title “Lord of Monaco” in 1342. In 1346 and 1355, the Grimaldis acquired the seigneuries and fiefs of Menton and Roquebrune. Together with that of Monaco, these seigneuries were to comprise the Principality’s territory from 1633 to 1861.

Before his death in 1454, Jean I made some fundamental arrangements in his will which would constitute the basis for succession in the House of Monaco for the next five centuries. He decreed that male children would succeed by order of primogeniture: if there were no male descendants, only then would women be called upon, on condition that their descendants take the Grimaldi name and coat-of-arms.

During the 15th century, the Seigneurie was recognized notably by the Duke of Savoy and, in 1512, by the King of France: all vassalage to Genoa thus disappeared. Lambert Grimaldi, who was Sovereign Lord of Monaco from 1458 to 1494, was Counsellor and Chamberlain to Charles VIII of France; this privileged relationship at the highest level of State extended the activities of Rainier I and Charles I.

Alliances brought the Lords of Monaco to move closer to France, to fight against Naples, to fall under the protection of Spain from 1524 to 1641, before King Louis XIII of France, in the Treaty of Péronne (1641), finally repositioned the Principality within France’s sphere of influence.

In 1633, the Spanish Chancery recognized  the title “Prince of Monaco” which had been used as early as 1612 by Honoré II when signing his notarial deeds. The Treaty of Péronne declared attribution of the fiefs of Le Valentinois, Carladès, Les Baux and Saint-Rémy to Prince Honoré II and his son. In December 1678, Louis I promulgated the legal statutes of the Principality, also known as the “Code Louis”. The attachment  of “Fort d’Hercule” to France in 1793 was not to last, as the Princes’ rights and prerogatives  were restored to them by the Treaty of Paris in 1814.


From the 19th century to the present day

Charles III sold his rights to Menton and Roquebrune to France in February 1861, in a treaty in which one clause provided for the creation of a customs union between the two States. This was concluded in 1865.

The Casino / Opera house

The Société des Bains de Mer was created in 1856, together with the Casino. Several hotels were built on the Plateau des Spélugues which, in 1866, was given the name “Monte-Carlo” (Mount-Charles, after the name of the reigning Prince).

His son, Prince Albert I, nicknamed the “Navigator Prince” or “Scientist Prince”, was responsible for great advances achieved in life sciences at the dawn of the 20th century. In 1910, Prince Albert I founded the well-known Museum of Oceanography in Monaco, which he bequeathed in his will to the Oceanographic Institute he had founded in Paris.

In 1911, he gave Monaco a constitutional structure. The Institute of Human Paleontology, devoted above all to research, was inaugurated in Paris in 1920.

In 1922, Prince Louis II succeeded him to the throne. Under his reign, the Medico-Legal Committee of Monaco was created in 1933, sketching out the bases for the Geneva Conventions of 1949. In the meantime, on 8 July 1948, the Principality became a member of the World Health Organisation.

In 1949, Prince Rainier III (Rainier Louis Henri Maxence Bertrand Grimaldi, prince of Monaco) mounted the throne. His reign was one which transformed the Principality the most. He intensified and diversified activities introduced under the three preceding reigns, not only in political, diplomatic, international, economic and social fields, but also in those of education and sport, healthcare,  science, culture and communication. He also added an industrial dimension to the Principality.

Ranier III and Grace Kelly

In 1955, Ranier III started courting and eventually married movie star Grace Kelly. On 17 December 1962, Prince Rainier III endowed the Principality with a new Constitution. In 1993, he obtained Monaco’s admission as a Member State in the United Nations Organisation. On 5 October 2004, after proceedings which had lasted for six years, the Principality of Monaco joined the Council of Europe as the 46th Member State of this organisation. At the official ceremony in Strasbourg, Prince Albert II declared, on behalf of his father, Prince Rainier III : “Admission of the Principality of Monaco to the Council of Europe is for me, as for all my countrymen, a subject for legitimate satisfaction and pride”. “I am very happy that Monaco has been admitted to an Organisation inspired by such noble aspirations thanks to the rich diversity of the nations it represents”.

For more than seven centuries, the Grimaldi Family has presided over the Principality of Monaco’s destiny. This remarkable longevity is a good illustration of the national unity between the Princes and the people of Monaco.

It’s hard to imagine, looking at Monaco now, that this magnificent cliff-side city of opulent casinos and grand hotels was teetering on the edge of financial ruin in the 1950s, and held precious little influence or renown on the world stage.

Enter shipping magnate and superyacht owner Aristotle Onassis, who bought up control of the failing Monegasque bank and encouraged Prince Rainier III to marry an American actress to bring star power to shine on the Principality. The more famous, the better.

the First meeting between the Prince Rainier of Monaco and Grace Kelly at the Palais de Monaco on May 6, 1955.

And so it was that screen goddess Grace Kelly met with the Prince at the palace during the 1955 Cannes Film Festival, posing for photos in a carefully contrived ‘meet-cute’ in front of a lion cage in the palace grounds (see all the photos here).

Grace Kelly’s 1956 wedding to Prince Rainier involved two ceremonies: one civil and one religious. The former included a reception attended by approximately 3,000 citizens of Monaco and the latter, a 700-person guest list that included Conrad Hilton, Cary Grant, and Ava Gardner. As one Boston Globe writer cleverly observed at the time: “Never have so many women brought so much luggage to such a small country for so few days.” The same could be said for the bride-to-be, who sailed to Monaco from New York for the occasion with 80 pieces of luggage and her beloved poodle, Oliver, in tow. When she arrived, 1,800 photographers and reporters were waiting at the port to capture Kelly exiting the ship and, naturally, falling into her prince’s arms.

The glamorous marriage succeeded in reinvigorating Monaco’s fortunes as intended. By 1961, five years after the wedding of the century, Monaco’s business turn over had reached $128 million—a 400% increase in ten years.

Charles de Gaulle, the former president of France had long expressed the desire to annex the principality of Monaco but decided not to push through in 1962—sparing the details as to why—but partly because of Her Serene Highness, Princess Grace of Monaco. The congenitally anti-American de Gaulle was enchanted by her insistence on speaking to him only in French, and found her lapses of grammar and pronunciation “charming”.

Sadly, Princess Grace was killed in a car crash in 1982, driving on the same high, beautiful Corniche road along the coast that she traveled with Cary Grant in Hitchcock’s ‘To Catch a Thief’, back when she was the most famous actress in the world. Her legacy, and the changes she brought to Monaco, live on.
