Since then, every Prince of Monaco has been a member of the House of Grimaldi. However, since the 18th century the princes have been agnatic descendants of other families that have inherited through the female line and adopted the Grimaldi name. In 1715, Jacques Goyon de Matignon married the last Grimaldi agnatic heir. He and his male line descendants, adopting the Grimaldi name, ruled as princes of Monaco from 1731 to 1949. Since then, the princes have been male line descendants of the Polignac family. Rainier III, son of Pierre de Polignac, inherited the title through his mother in 1949 and adopted the Grimaldi name. During much of the Ancien Régime, the family resided in the French court, where from 1642 to 1715 they used the title of Duke of Valentinois.
The current head of the house is Albert II of Monaco, Sovereign Prince of Monaco, who is the son and successor of Prince Rainier III and the Princess consort Grace of Monaco, formerly known as Grace Kelly.
The Grimaldis feared that the head of a rival Genoese family could break the fragile balance of power in a coup and become lord of Genoa, as had happened in other Italian cities. They entered into a Guelphic alliance with the Fieschi family. In 1271, the Guelphs were banned from Genoa, and the Grimaldi took refuge in their castles in Liguria and Provence. They signed a treaty with Charles of Anjou, King of Sicily and Count of Provence to retake control of Genoa. In 1276, they accepted a peace under the auspices of the Pope, but the civil war continued. Not all the Grimaldis chose to return to Genoa and instead settled in their fiefdoms, where they could raise armies.
In 1299, the Grimaldis and their allies launched a few galleys to attack the port of Genoa before taking refuge on the Western Riviera. During the following years, the Grimaldis entered into different alliances that would allow them to return to power in Genoa. This time, it was the turn of their rivals, the Spinola family, to be exiled from the city. During this period, both the Guelphs and Ghibellines took and abandoned the castle of Monaco, which was ideally located to launch political and military operations against Genoa. Therefore, the tale of Francis Grimaldi and his faction – who took the castle of Monaco disguised as friars in 1297 – is largely anecdotal.
In the early 14th century, the Aragonese raided the shores of Provence and Liguria, challenging Genoa and King Robert of Provence. In 1353, the combined fleet of eighty Venetian and Aragonese galleys gathered in Sardinia to meet the fleet of sixty galleys under the command of Anthony Grimaldi. Only nineteen Genoese vessels survived the battle. Fearing an invasion, Genoa requested the protection of the Lord of Milan.
Several of the oldest feudal branches of the House of Grimaldi appeared during these conflicts, such as the branches of Antibes, Beuil, Nice, Puget, and Sicily. In 1395, the Grimaldis took advantage of the discords in Genoa to take possession of Monaco, which they then ruled as a condominium. This is the origin of today's principality.
As was customary in Genoa, the Grimaldis organised their family ties within a corporation called albergo. In the political reform of 1528, the Grimaldi became one of the 28 alberghi of the Republic of Genoa, which included the Doria and Pallavicini families, and to which other families were formally invited to join. The House of Grimaldi provided several doges, cardinals, cabinet ministers, and military officers of historical note.
French influences
Provence became a part of the Kingdom of France from 1486, and occasionally the Grimaldi relied upon French support to preserve their independence from the Republic of Genoa and the Duchy of Savoy. In the process they married into the French nobility in the 1600s, inherited French estates, and often lived in Paris, latterly at the Hôtel Matignon, until the French Revolution of 1789. Monaco and the neighbouring County of Nice was taken by the revolutionary army in 1792, and were French-controlled until 1815. Nice passed back to the Kingdom of Sardinia in 1815; then it was ceded to France by the Treaty of Turin (1860). Monaco was re-established by the Congress of Vienna in 1815, with a brief Italian occupation in 1940–43.
Modern succession
By convention, membership of sovereign European houses is through the male line. By that definition, from 1731 the French noble House of Goyon-Matignon ruled as Princes of Monaco until 1949. However, one of the terms of James de Goyon de Matignon becoming Prince of Monaco jure uxoris was that he adopt the name and arms of Grimaldi so that the house would be preserved on the throne, and the right of succession was through his wife Louise-Hippolyte Grimaldi, who abdicated in her husband's favor.[citation needed] Similarly, when Charlotte Louvet was legitimised in 1911 and made successor to Monaco, her husband, Count Pierre de Polignac, adopted, as a condition of the marriage, the name and arms of Grimaldi, but from this moment all his direct descendants Grimaldi would also have the title of Counts of Polignac. In this way the "Grimaldi" name and arms were continued.[citation needed]
Under the succession rules prior to 1911, Monaco’s throne would have passed to Prince Wilhelm of Urach. However, French president at the time Raymond Poincaré had threatened that if the throne was inherited by a German, France would annex the principality.[1]
In 2018 a Grimaldi cousin, Count Louis de Causans, who hailed from a cadet branch of the family, sued France for €351m compensation, claiming that it had deceived his family during the succession crisis of 1911, and that his great-grandfather, Count Aynard de Chabrillan, should have inherited Monaco's throne.[2][3][4]
Until 2002, a treaty between Monaco and France stated that if the reigning Prince ever failed to leave dynastic offspring, then sovereignty over the Grimaldi realm would revert to France. The 2002 agreement modified this to expand the pool of potential heirs to dynastic collaterals of the reigning Prince (excluding adoptive heirs, hitherto allowed, e.g. Princess Charlotte and her descendants), guaranteeing Monegasque independence. Article I of Monaco's house law requires that the reigning Prince or Princess bear the surname of Grimaldi.
The coat of arms of the House of Grimaldi is simply described as fusily argent and gules, i.e., a red and white diamond pattern, with no further modifiers.
Girolamo (died 1543). Created a Cardinal in 1527. He married Francisca Cattaneo of Genoese and had five children. After her death he entered holy orders. He was a Senator of Genoa.

The early history of Monaco is primarily concerned with the protective and strategic value of the Rock of Monaco, the area's chief geological landmark, which served first as a shelter for ancient peoples and later as a fortress. Part of Liguria's history since the fall of the Roman Empire, from the 14th to the early 15th century the area was contested for primarily political reasons. Since that point, excepting a brief period of French occupation, it has remained steadily under the control of the House of Grimaldi.
Rainier III was Prince of Monaco from 1949 to his death in 2005. Rainier ruled the Principality of Monaco for almost 56 years.
Princess Charlotte, Duchess of Valentinois, styled Hereditary Princess of Monaco between 1922 and 1944, was the daughter of Louis II, Prince of Monaco, and mother of Prince Rainier III. From 1922 until 1944, she was the Hereditary Princess of Monaco, heiress presumptive to the throne.
Princess Antoinette, Baroness of Massy was a member of the princely family of Monaco. She was the elder sister of Prince Rainier III. Her parents were Princess Charlotte, Duchess of Valentinois and her former husband, Count Pierre de Polignac.
Princess Caroline Louise Marguerite of Monaco is Princess of Hanover by marriage to Prince Ernst August. As the eldest child of Rainier III, Prince of Monaco, and Grace Kelly, she is the elder sister of Albert II, Prince of Monaco, and Princess Stéphanie.
The succession to the throne of the Principality of Monaco is currently governed by Princely Law 1.249 of 2 April 2002.
Monaco City is the southcentral ward in the Principality of Monaco. Located on a headland that extends into the Mediterranean Sea, it is nicknamed The Rock. The name "Monaco City" is misleading: it is not itself a city, but a historical and statistical district. It holds most of the country's political and judicial institutions: the Prince's Palace, the town hall, the government, the National Council, the Municipal Council, the courts and a prison.
Andrea Albert Pierre Casiraghi is the elder son of Caroline, Princess of Hanover, and her second husband Stefano Casiraghi. He is the eldest grandchild of Rainier III, Prince of Monaco, and American actress Grace Kelly. Casiraghi is currently fourth in the line of succession to the Monegasque throne, following his twin cousins and his mother.
Duke of Valentinois is a title of nobility, originally in the French peerage. It is currently one of the many hereditary titles claimed by the Prince of Monaco despite its extinction in French law in 1949. Though it originally indicated administrative control of the Duchy of Valentinois, based around the city of Valence, the duchy has since become part of France, making the title simply one of courtesy.
The sovereign prince is the monarch and head of state of the Principality of Monaco. All reigning princes and princesses have taken the name of the House of Grimaldi. When Prince Rainier III died in 2005, he was Europe's longest reigning monarch. The Grimaldi family, which has ruled Monaco for eight centuries, is Europe's longest-ruling royal family.
Grimaldo Canella was the youngest son of Otto Canella and Consul of Genoa in 1162, 1170, and 1184. Grimaldo is considered the progenitor and eponym of the House of Grimaldi.
Louise Hippolyte was Princess of Monaco from 20 February 1731 until her death in December that same year. She was one of only two women to rule Monaco.
The Monaco succession crisis of 1918 arose because France objected to the prospect of a German national inheriting the throne of the Principality of Monaco. Prince Albert I had only one legitimate child, the Hereditary Prince Louis, then heir apparent to the principality. As World War I drew to a close, Prince Louis, at the age of forty-eight, remained without legitimate issue, unmarried, and unbetrothed.
The Prince's Palace of Monaco is the official residence of the Sovereign Prince of Monaco. Built in 1191 as a Genoese fortress, during its long and often dramatic history it has been bombarded and besieged by many foreign powers. Since the end of the 13th century, it has been the stronghold and home of the Grimaldi family who first captured it in 1297. The Grimaldi ruled the area first as feudal lords, and from the 17th century as sovereign princes, but their power was often derived from fragile agreements with their larger and stronger neighbours.
Jacques I was Prince of Monaco from 1731 to 1733. He was also Duke of Valentinois from 1716 until 1733, and Count of Thorigny. For ten months preceding his accession, he had served as prince consort to his wife, Louise Hippolyte, Princess of Monaco.
Marie de Lorraine was a princess of the House of Lorraine-Guise and Princess of Monaco as consort of Antonio I of Monaco. She was the mother of Louise Hippolyte Grimaldi, the only sovereign Princess of Monaco.

Giuseppe Maria Brignole-Sale (1703–1769) was a Genoese nobleman and father of Maria Caterina Brignole, Princess of Monaco and later Princess of Condé. He was the 7th Marquess of Groppoli. The reigning Albert II of Monaco is a direct descendant.
The Château des Matignon is a former princely residence located in Torigni-sur-Vire in the Manche department, Normandy, northwestern France. The southern wing that you see today is all that remains of the castle from the 16th and 17th centuries. Originally, there were three wings enclosing a main courtyard that opened to the west, but it suffered substantial damage during the French Revolution. The castle's history is closely related to the Matignon family and the princely family of Monaco, the House of Grimaldi. Presently, the château is owned by the local municipality, serving both as its administrative offices and as a museum.
