The Truce of Leulinghem was a truce agreed to by Richard II's kingdom of England and its allies, and Charles VI's kingdom of France and its allies, on 18 July 1389, ending the second phase of the Hundred Years' War. England was on the edge of financial collapse and suffering from internal political divisions. On the other side, Charles VI was suffering from a mental illness that handicapped the furthering of the war by the French government. Neither side was willing to concede on the primary cause of the war, the legal status of the Duchy of Aquitaine and the King of England's homage to the King of France through his possession of the duchy. However, both sides faced major internal issues that could badly damage their kingdoms if the war continued. The truce was originally negotiated by representatives of the kings to last three years, but the two kings met in person at Leulinghem, near the English fortress of Calais, and agreed to extend the truce to a twenty-seven years' period. Other provisions were agreed to, in attempts to bring an end to the Papal schism, to launch a joint crusade against the Turks in the Balkans, to seal the marriage of Richard to Charles' daughter Isabella along with an 800,000 franc dowry, and to guarantee to continue peace negotiations, in order to establish a lasting treaty between the kingdoms. The treaty brought peace to the Iberian peninsula, where Portugal and Castile were supporting the English and French respectively. The English evacuated all their holdings in northern France except Calais.

The truce was the result of a decade of failed peace negotiations and inaugurated a thirteen years peace, the longest period of sustained peace during the Hundred Years' War. During the years following the truce, Richard reneged on his agreement to assist in ending the schism, leading the French to unilaterally withdraw from the obedience of either pope and seize Avignon by military force. French foreign policy also began to focus on Italy, and Genoa became a French protectorate. In England, Richard used the lapse in fighting to attack his political enemies and confiscate their lands, which he redistributed as rewards to his supporters. He then left for Ireland to put down a revolt among the Irish chieftains, but during his absence a number of his exiled opponents returned, led by his cousin Henry of Bolingbroke, Duke of Lancaster. Henry began an insurrection and seized most of England before Richard could return. Upon his return, Richard was imprisoned, and before he was starved to death he was forced to agree to abdicate. Henry was crowned in his place. The French initially interpreted events in England as a repudiation of the truce and raised an army and put garrisons in place on the fronts. Henry IV reaffirmed the truce which remained in place for several more years.

Henry made a number of aggressive political moves against France in the following years, marrying Joanna, widow of the duke of Brittany in April 1402, and forming alliances with several German rulers, including a marriage alliance with Bavaria. Scotland was the first nation to break the truce, invading England in August in coordination with a revolt in Wales. The French reentered the conflict in September 1403, landing an army in Wales.



The Kingdom of France (Old French: Reaume de France; Middle French: Royaulme de France; French: Royaume de France) is the historiographical name or umbrella term given to various political entities of France in the medieval and early modern period. It was among the most powerful states in Europe and a great power from the High Middle Ages onward. It was also an early colonial power, with possessions around the world.

France originated as West Francia (Francia Occidentalis), the western half of the Carolingian Empire, 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—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).

France in the Middle Ages was a de-centralised, feudal monarchy. In Brittany and Catalonia (now a part of Spain) the authority of the French king was barely felt. Lorraine and Provence were states of the Holy Roman Empire and not yet a part of France. Initially, West Frankish kings were elected by the secular and ecclesiastic magnates, but the regular coronation of the eldest son of the reigning king during his father's lifetime established the principle of male primogeniture, which became codified in the Salic law. During the Late Middle Ages, rivalry between the Capetian Dynasty, rulers of the Kingdom of France and their vassals the House of Plantagenet, who also ruled the Kingdom of England as part of their so-called competing Angevin Empire, resulted in many armed struggles. The most notorious of them all are the series of conflicts known as the Hundred Years' War (1337–1453) in which the kings of England laid claim to the French throne. Emerging victorious from said conflicts, France subsequently sought to extend its influence into Italy, but was defeated by Spain and the Holy Roman Empire in the ensuing Italian Wars (1494–1559).

France in the early modern era was increasingly centralised; the French language began to displace other languages from official use, and the monarch expanded his absolute power, albeit in an administrative system (the Ancien Régime) complicated by historic and regional irregularities in taxation, legal, judicial, and ecclesiastic divisions, and local prerogatives. Religiously France became divided between the Catholic majority and a Protestant minority, the Huguenots, which led to a series of civil wars, the Wars of Religion (1562–1598). The Wars of Religion crippled France, but triumph over Spain and the Habsburg Monarchy in the Thirty Years' War made France the most powerful nation on the continent once more. The kingdom became Europe's dominant cultural, political and military power in the 17th century under Louis XIV. In parallel, France developed its first colonial empire in Asia, Africa, and in the Americas. From the 16th to the 17th centuries, the First French colonial empire stretched from a total area at its peak in 1680 to over 10,000,000 square kilometres (3,900,000 sq mi), the second largest empire in the world at the time behind only the Spanish Empire. Colonial conflicts with Great Britain led to the loss of much of its North American holdings by 1763. French intervention in the American Revolutionary War helped secure the independence of the new United States of America but was costly and achieved little for France.

The Kingdom of France adopted a written constitution in 1791, but the Kingdom was abolished a year later and replaced with the First French Republic. The monarchy was restored by the other great powers in 1814 and lasted (except for the Hundred Days in 1815) until the French Revolution of 1848.
