Philip II of France in the context of "Treaty of Le Goulet"

Richard I (8 September 1157 – 6 April 1199), known as Richard the Lionheart or Richard Cœur de Lion (Old Norman French: Quor de Lion) because of his reputation as a great military leader and warrior, was King of England from 1189 until his death in 1199. He also ruled as Duke of Normandy, Aquitaine, and Gascony; Lord of Cyprus; Count of Poitiers, Anjou, Maine, and Nantes; and was overlord of Brittany at various times during the same period. He was the third of five sons of Henry II of England and Eleanor of Aquitaine and was therefore not expected to become king, but his two elder brothers predeceased their father.

By the age of 16, Richard had taken command of his own army, putting down rebellions in Poitou against his father. Richard was an important Christian commander during the Third Crusade, leading the campaign after the departure of Philip II of France. Despite achieving several victories against his Muslim counterpart, Saladin, he was ultimately forced to end his campaign without retaking Jerusalem.

John (24 December 1166 – 19 October 1216) was King of England from 1199 until his death in 1216. He lost the Duchy of Normandy and most of his other French lands to King Philip II of France, resulting in the collapse of the Angevin Empire and contributing to the subsequent growth in power of the French Capetian dynasty during the 13th century. The baronial revolt at the end of John's reign led to the sealing of Magna Carta, a document considered a foundational milestone in English and later British constitutional history.

John was the youngest son of King Henry II of England and Duchess Eleanor of Aquitaine. He was nicknamed John Lackland (Norman: Jean sans Terre, lit. 'John without land') because, as a younger son, he was not expected to inherit significant lands. He became Henry's favourite child following the failed revolt of 1173–1174 by his brothers Henry the Young King, Richard, and Geoffrey against their father. John was appointed Lord of Ireland in 1177 and given lands in England and on the continent. During the reign of his brother Richard I, he unsuccessfully attempted a rebellion against Richard's royal administrators while the King was participating in the Third Crusade, but he was proclaimed king after Richard died in 1199. He came to an agreement with Philip II of France to recognise John's possession of the continental Angevin lands at the peace treaty of Le Goulet in 1200.

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 Kingdom of France is the historiographical name or umbrella term given to various political entities of France in the medieval and early modern period. It was one of the most powerful states in Europe from the High Middle Ages to 1848 during its dissolution. It was also an early colonial power, with colonies in Asia and Africa, and the largest being New France in North America geographically centred on the Great Lakes.

The Kingdom of France was descended directly from the western Frankish realm of the Carolingian Empire, which was ceded to Charles the Bald with the Treaty of Verdun (843). A branch of the Carolingian dynasty continued to rule until 987, when Hugh Capet was elected king and founded the Capetian dynasty. The territory remained known as Francia and its ruler as rex Francorum ('king of the Franks') well into the High Middle Ages. The first king calling himself rex Francie ('King of France') was Philip II, in 1190, and officially from 1204. From then, France was continuously ruled by the Capetians and their cadet lines under the Valois and Bourbon until the monarchy was abolished in 1792 during the French Revolution. The Kingdom of France was also ruled in personal union with the Kingdom of Navarre over two time periods, 1284–1328 and 1572–1620, after which the institutions of Navarre were abolished and it was fully annexed by France (though the King of France continued to use the title "King of Navarre" through the end of the monarchy).

The Third Crusade (1189–1192) was an attempt led by King Philip II of France, King Richard I of England and Emperor Frederick Barbarossa to reconquer the Holy Land following the capture of Jerusalem by the Ayyubid sultan Saladin in 1187. For this reason, the Third Crusade is also known as the Kings' Crusade.

It was partially successful, recapturing the important cities of Acre and Jaffa, and reversing most of Saladin's conquests, but it failed to recapture Jerusalem, which was the major aim of the Crusade and its religious focus.

The Angevin Empire (/ˈændʒɪvɪn/; French: Empire Plantagenêt) was the collection of territories held by the House of Plantagenet during the 12th and 13th centuries, when they ruled over an area covering roughly all of present-day England, half of France, and parts of Ireland and Wales, and claiming overlordship and some influence over the remaining parts of Wales, Scotland and Ireland. It may be described as an early example of a composite monarchy. The empire was established by Henry II of England, who succeeded his father Geoffrey as duke of Normandy and count of Anjou (from the latter of which the term Angevin is derived). Henry married Eleanor of Aquitaine in 1152, acquiring the Duchy of Aquitaine, and inherited his mother Empress Matilda's claim to the English throne, succeeding his rival Stephen in 1154. Although their title of highest rank came from the Kingdom of England, the Plantagenets held court primarily on the continent at Angers in Anjou and at Chinon in Touraine.

The influence and power of the Angevin kings of England brought them into conflict with the kings of France of the House of Capet, to whom they also owed feudal homage for their French possessions, bringing in a period of rivalry between the dynasties. Despite the extent of Angevin rule, Henry's son King John was defeated in the Anglo-French War (1213–1214) by Philip II of France following the Battle of Bouvines. John lost control of most of his continental possessions, apart from Guyenne and Gascony in southern Aquitaine. This defeat set the scene for further conflicts between England and France, leading up to the Hundred Years' War (1337–1453), in which the Plantagenets re-established dominion over much of western, central, and northern France before losing their possessions again, this time permanently.

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 First Barons' War (1215–1217) was a civil war in the Kingdom of England in which a group of rebellious major landowners (commonly referred to as barons) led by Robert Fitzwalter waged war against King John. The conflict resulted from King John's disastrous wars against King Philip II of France which led to the collapse of the Angevin Empire, and John's subsequent refusal to accept and abide by Magna Carta, which John had sealed on 15 June 1215.

The rebellious barons, faced with an uncompromising king, turned to King Philip's son Louis, who in 1216 sailed to England with an army despite his father's and the pope's disapprovals. Louis captured Winchester and soon controlled over half of the English kingdom. He was proclaimed "King of England" in London by the barons, although he was never actually crowned.
