Henry IV of France in the context of "Edict of Versailles"

The ancien régime (/ˌɒ̃sjæ̃ reɪˈʒiːm/; French: [ɑ̃sjɛ̃ ʁeʒim] ; lit. 'old rule') was the political and social system of the Kingdom of France that the French Revolution overturned through its abolition in 1790 of the feudal system of the French nobility and in 1792 through its execution of King Louis XVI and declaration of a republic. "Ancien régime" is now a common metaphor for "a system or mode no longer prevailing".

The administrative and social structures of the ancien régime in France evolved across years of state-building, legislative acts (like the Ordinance of Villers-Cotterêts), and internal conflicts. The attempts of the House of Valois to reform and re-establish control over the scattered political centres of the country were hindered by the Wars of Religion from 1562 to 1598. During the House of Bourbon, much of the reigns of Henry IV (r. 1589–1610) and Louis XIII (r. 1610–1643) and the early years of Louis XIV (r. 1643–1715) focused on administrative centralization. Despite the notion of "absolute monarchy" (typified by the king's right to issue orders through lettres de cachet) and efforts to create a centralized state, ancien régime France remained a country of systemic irregularities: administrative, legal, judicial, and ecclesiastic divisions and prerogatives frequently overlapped, the French nobility struggled to maintain their influence in local judiciary and state branches while the Fronde and other major internal conflicts violently contested additional centralization.

The first written records for the history of France appeared in the Iron Age. What is now France made up the bulk of the region known to the Romans as Gaul. Greek writers noted the presence of three main ethno-linguistic groups in the area: the Gauls, Aquitani and Belgae. Over the first millennium BC the Greeks, Romans and Carthaginians established colonies on the Mediterranean coast and offshore islands. The Roman Republic annexed southern Gaul in the late 2nd century BC, and legions under Julius Caesar conquered the rest of Gaul in the Gallic Wars of 58–51 BC. A Gallo-Roman culture emerged, and Gaul was increasingly integrated into the Roman Empire. In the later stages of the empire, Gaul was subject to barbarian raids and migration. The Frankish king Clovis I united most of Gaul in the late 5th century. Frankish power reached its fullest extent under Charlemagne. The medieval Kingdom of France emerged from the western part of Charlemagne's Carolingian Empire, known as West Francia, and achieved increasing prominence under the rule of the House of Capet, founded in 987.

A succession crisis in 1328 led to the Hundred Years' War between the House of Valois and the House of Plantagenet. The war began in 1337 following Philip VI's attempt to seize the Duchy of Aquitaine from its hereditary holder Edward III of England, the Plantagenet claimant to the French throne. A notable figure of the war was Joan of Arc, a French peasant girl who led forces against the English, establishing herself as a national heroine. The war ended with a Valois victory in 1453, strengthening French nationalism and increasing the power and reach of the French monarchy. During the Ancien Régime over the next centuries, France transformed into a centralized absolute monarchy through the Renaissance and Reformation. At the height of the French Wars of Religion, France became embroiled in another succession crisis, as the last Valois king, Henry III, fought against factions of the House of Bourbon and House of Guise. Henry, the Bourbon King of Navarre, won and established the Bourbon dynasty. A burgeoning worldwide colonial empire was established in the 16th century.

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 French Wars of Religion were a series of civil wars between French Catholics and Protestants (called Huguenots) from 1562 to 1598. Between two and four million people died from violence, famine or disease directly caused by the conflict, and it severely damaged the power of the French monarchy. One of its most notorious episodes was the St. Bartholomew's Day massacre in 1572. The fighting ended with a compromise in 1598, when Henry of Navarre, who converted to Catholicism in 1593, was proclaimed King Henry IV of France and issued the Edict of Nantes, which granted substantial rights and freedoms to the Huguenots. However, Catholics continued to disapprove of Protestants and of Henry, and his assassination in 1610 triggered a fresh round of Huguenot rebellions in the 1620s.

Tensions between the two religions had been building since the 1530s, exacerbating existing regional divisions, and quests for power among the nobles. The sudden accidental death of Henry II of France in July 1559 initiated a prolonged struggle for power between his widow Catherine de' Medici and powerful nobles. These included a fervently Catholic faction led by the Guise and Montmorency families, and Protestants headed by the House of Condé and the Navarrese queen, Jeanne d'Albret. Both sides received assistance from external powers, with Spain and Savoy supporting the Catholics, and England and the Dutch Republic backing the Protestants.

The Basilica of Saint-Denis (French: Basilique royale de Saint-Denis, now formally known as the Basilique-cathédrale de Saint-Denis) is a large former medieval abbey church and cathedral in the commune of Saint-Denis, a northern suburb of Paris. The building is of singular importance historically and architecturally as its choir, completed in 1144, is widely considered the first structure to employ all of the elements of Gothic architecture.

The basilica became a place of pilgrimage and a necropolis containing the tombs of the kings of France, including nearly every king from the 10th century to Louis XVIII in the 19th century. Henry IV of France came to Saint-Denis formally to renounce his Protestant faith and become a Catholic. The queens of France were crowned at Saint-Denis, and the regalia, including the sword used for crowning the kings and the royal sceptre, were kept at Saint-Denis between coronations.

Louis XIII (French pronunciation: [lwi tʁɛz]; sometimes called the Just; 27 September 1601 – 14 May 1643) was King of France from 1610 until his death in 1643 and King of Navarre (as Louis II) from 1610 to 1620, when the crown of Navarre was merged with the French crown.

Shortly before his ninth birthday, Louis became king of France and Navarre after his father Henry IV was assassinated. His mother, Marie de' Medici, acted as regent during his minority. Mismanagement of the kingdom and ceaseless political intrigues by Marie and her Italian favourites led the young king to take power in 1617 by exiling his mother and executing her followers, including Concino Concini, the most influential Italian at the French court.

The Edict of Nantes (French: édit de Nantes) was an edict signed in April 1598 by King Henry IV and granted the minority Calvinist Protestants of France, also known as Huguenots, substantial rights in the nation, which was predominantly Catholic.

While upholding Catholicism as the established religion, and requiring the re-establishment of Catholic worship in places it had lapsed, it granted certain religious toleration to the Protestant Huguenots, who had been waging a long and bloody struggle for their rights in France.
