Francis I of France in the context of "Cellini Salt Cellar"

Leonardo di ser Piero da Vinci (15 April 1452 – 2 May 1519) was an Italian polymath of the High Renaissance who was active as a painter, draughtsman, engineer, scientist, theorist, sculptor, and architect. While his fame initially rested on his achievements as a painter, he has also become known for his notebooks, in which he made drawings and notes on a variety of subjects, including anatomy, astronomy, botany, cartography, painting, and palaeontology. Leonardo is widely regarded to have been a genius who epitomised the Renaissance humanist ideal, and his collective works comprise a contribution to later generations of artists matched only by that of his younger contemporary Michelangelo.

Born out of wedlock to a successful notary and a lower-class woman in, or near, Vinci, he was educated in Florence by the Italian painter and sculptor Andrea del Verrocchio. He began his career in the city, but then spent much time in the service of Ludovico Sforza in Milan. Later, he worked in Florence and Milan again, as well as briefly in Rome, all while attracting a large following of imitators and students. Upon the invitation of Francis I, he spent his last three years in France, where he died in 1519. Since his death, there has not been a time when his achievements, diverse interests, personal life, and empirical thinking have failed to incite interest and admiration, making him a frequent namesake and subject in culture.

The Louvre, or the Louvre Museum (French: Musée du Louvre [myze dy luvʁ] ), is a national art museum in Paris, France, and the most visited museum in the world. It is located on the Right Bank of the Seine in the city's 1st arrondissement (district) and home to some of the most canonical works of Western art, including the Mona Lisa, Venus de Milo, and Winged Victory. The museum is housed in the Louvre Palace, originally built in the late 12th to 13th century under Philip II. Remnants of the Medieval Louvre fortress are visible in the basement of the museum. Due to urban expansion, the fortress eventually lost its defensive function, and in 1546 Francis I converted it into the primary residence of the French kings.

The building was redesigned and extended many times to form the present Louvre Palace. In 1682, Louis XIV chose the Palace of Versailles for his household, leaving the Louvre primarily as a place to display the royal collection, including, from 1692, a collection of ancient Greek and Roman sculpture. In 1692, the building was occupied by the Académie des Inscriptions et Belles-Lettres and the Académie Royale de Peinture et de Sculpture, which in 1699 held the first of a series of salons. The Académie remained at the Louvre for 100 years. During the French Revolution, the National Assembly decreed that the Louvre should be used as a museum to display the nation's masterpieces. The palace and exhibition space was expanded in the 19th century and again in the 20th.

The Mona Lisa is a half-length portrait painting by the Italian artist Leonardo da Vinci. Considered an archetypal masterpiece of the Italian Renaissance, it has been described as "the best known, the most visited, the most written about, the most sung about, [and] the most parodied work of art in the world." The painting's novel qualities include the subject's enigmatic expression, monumentality of the composition, the subtle modelling of forms, and the atmospheric illusionism.

The painting has been traditionally considered to depict the Italian noblewoman Lisa del Giocondo. It is painted in oil on a white poplar panel. Leonardo never gave the painting to the Giocondo family. It was believed to have been painted between 1503 and 1506; however, Leonardo may have continued working on it as late as 1517. King Francis I of France acquired the Mona Lisa after Leonardo's death in 1519, and it became the property of the French Republic. It has normally been on display at the Louvre in Paris since 1797.

The Capetian dynasty (/kəˈpiːʃən/ kə-PEE-shən; French: Capétiens/ka.pe.sjɛ̃/), also known as the House of France (French: La Maison de France), is a dynasty of Frankish origin, and a branch of the Robertians agnatically, and the Carolingians through female lines. It is among the largest and oldest royal houses in Europe and the world, and consists of Hugh Capet, the founder of the dynasty, and his male-line descendants, who ruled in France without interruption from 987 to 1792, and again from 1814 to 1848. The senior line from the House of Capet ruled in France from the election of Hugh Capet in 987 until the death of Charles IV in 1328. That line was succeeded by cadet branches, first the House of Valois, and succeeding them the House of Bourbon, which ruled until the French Revolution abolished the monarchy in 1792 and tried and executed King Louis XVI in 1793. The Bourbons were restored in 1814 in the aftermath of Napoleon's defeat, but had to vacate the throne again in 1830 in favor of the last Capetian monarch of France, Louis Philippe I, who belonged to the House of Orléans, a cadet branch of the Bourbons. Cadet branches of the Capetian House of Bourbon are still reigning over Spain and Luxembourg.

The dynasty had a crucial role in the formation of the French state. From a power base initially confined to their own demesne, the Île-de-France, the Capetian kings slowly but steadily increased their power and influence until it grew to cover the entirety of their realm. For a detailed narration on the growth of French royal power, see Crown lands of France. Members of the dynasty were traditionally Catholic, and the early Capetians had an alliance with the Church. The French were also the most active participants in the Crusades, culminating in a series of five Crusader kings – Louis VII, Philip Augustus, Louis VIII, Louis IX, and Philip III. The Capetian alliance with the papacy suffered a severe blow after the disaster of the Aragonese Crusade. Philip III's son and successor, Philip IV, arrested Pope Boniface VIII and brought the papacy under French control. The later Valois, starting with Francis I, ignored religious differences and allied with the Ottoman sultan to counter the growing power of the Holy Roman Empire. Henry IV was a Protestant at the time of his accession, but realized the necessity of conversion after four years of religious warfare.

The Louvre Palace (French: Palais du Louvre, [palɛ dy luvʁ]), often referred to simply as the Louvre, is an iconic French palace located on the Right Bank of the Seine in Paris, occupying a vast expanse of land between the Tuileries Gardens and the church of Saint-Germain l'Auxerrois. Originally a defensive castle, it has served several government-related functions in the past, including intermittently as a royal residence between the 14th and 18th centuries. It is now mostly used by the Louvre Museum, which first opened there in 1793.

While this area along the Seine had been inhabited for thousands of years, the Louvre's history starts around 1190 with its first construction as the Louvre Castle defending the western front of the Wall of Philip II Augustus, the then new city-wall of Paris. The Louvre's oldest section still standing above ground, its palatial Lescot Wing, dates from the late 1540s, when Francis I started the replacement of the greatly expanded medieval castle with a new design inspired by classical antiquity and Italian Renaissance architecture. Most parts of the current building were constructed in the 17th and 19th centuries. In the late 20th century, the Grand Louvre project increased visitor access and gallery space, including by adding the Louvre Pyramid in the courtyard Cour Napoléon.

Palace of Fontainebleau (/ˈfɒntɪnbloʊ/ FON-tin-bloh, US also /-bluː/ -⁠bloo; French: Château de Fontainebleau [ʃɑto d(ə) fɔ̃tɛnblo]), located 55 kilometers (34 miles) southeast of the center of Paris, in the commune of Fontainebleau, is one of the largest French royal châteaux. It served as a hunting lodge and autumn residence for many of the French monarchs, including Louis VII, Francis I, Henry II, Louis-Philippe, Napoleon I, and Napoleon III. Though the monarchs only resided there for a few months of the year, they gradually transformed it into a genuine palace, filled with art and decoration. It became a national museum in 1927 and was designated a UNESCO World Heritage Site in 1981 for its unique architecture and historical importance.

The Franco-Ottoman alliance, also known as the Franco-Turkish alliance, was an alliance established in 1536 between Francis I, King of France and Suleiman I of the Ottoman Empire. The strategic and sometimes tactical alliance was one of the longest-lasting and most important foreign alliances of France, and was particularly influential during the Italian Wars. The Franco-Ottoman military alliance reached its peak with the Invasion of Corsica of 1553 during the reign of Henry II of France.

As the first non-ideological alliance in effect between a Christian and Muslim state, the alliance attracted heavy controversy for its time and caused a scandal throughout Christendom. Carl Jacob Burckhardt (1947) called it "the sacrilegious union of the lily and the crescent". It lasted intermittently for more than two and a half centuries, until the Napoleonic campaign in Ottoman Egypt, in 1798–1801.

La Belle Ferronnière (French pronunciation: [la bɛl fɛʁɔnjɛʁ]) is a portrait painting of a lady, by Leonardo da Vinci, in the Louvre. It is also known as Portrait of an Unknown Woman. The painting's title, applied as early as the seventeenth century, identifying the sitter as the wife or daughter of an ironmonger (a ferronnier), was said to be discreetly alluding to a reputed mistress of Francis I of France, married to a certain Le Ferron. Later she was tentatively identified as Lucretia Crivelli, a married lady-in-waiting to Duchess Beatrice of Milan, who became another of the Duke's mistresses.

Leonardo's Lady with an Ermine has also been known by this name. This was once believed to be a portrait of Cecilia Gallerani, one of the mistresses of Ludovico Sforza, Duke of Milan. The narrative and the title were applied to Lady with an Ermine when it was in Princess Izabela Czartoryska's collection, and became confused with La Belle Ferronnière by the presence of a ferronnière, a type of accessory worn across the forehead, in the painting as well.
