Philip VI, called the Fortunate or the Catholic and of Valois was the first king of France from the House of Valois, reigning from 1328 until his death in 1350. Philip's reign was dominated by the consequences of a succession dispute. When King Charles IV of France died in 1328, his nearest male relative was his sororal nephew, King Edward III of England, but the French nobility preferred Charles's paternal cousin, Philip.
Odo IV or Eudes IV was Duke of Burgundy from 1315 until his death and Count of Burgundy and Artois between 1330 and 1347, as well as titular King of Thessalonica from 1316 to 1320. He was the second son of Duke Robert II and Agnes of France.
The War of the Breton Succession was a conflict between the Counts of Blois and the Montforts of Brittany for control of the Sovereign Duchy of Brittany, then a fief of the Kingdom of France. It was fought between 1341 and 12 April 1365. It is also known as the War of the Two Jeannes due to the involvement of two rival duchesses of that name.
Henry of Grosmont, Duke of Lancaster was an English statesman, diplomat, soldier, and Christian writer. The owner of Bolingbroke Castle in Lincolnshire, Grosmont was a member of the House of Plantagenet, which was ruling over England at that time. He was the wealthiest and most powerful peer of the realm.
The siege of Calais occurred at the conclusion of the Crécy campaign, when an English army under the command of King Edward III of England successfully besieged the French town of Calais during the Edwardian phase of the Hundred Years' War.
The first phase of the Hundred Years' War between England and France lasted from 1337 to 1360. It is sometimes referred to as the Edwardian War because it was initiated by King Edward III of England, who claimed the French throne in defiance of King Philip VI of France. The dynastic conflict was caused by disputes over the French feudal sovereignty over Aquitaine and the English claims over the French royal title. The Kingdom of England and its allies dominated this phase of the war, and Edward's sovereignty over Aquitaine was confirmed in the Treaty of Brétigny (1360), although he renounced his claim to the French throne.
The Battle of Saint-Omer, fought on 26 July 1340, was a major engagement in the early stages of the Hundred Years' War, during Edward III's 1340 summer campaign against France launched from Flanders. The campaign was initiated in the aftermath of the English naval victory at the Battle of Sluys but was far less successful than Edward had hoped. At Saint-Omer, the heavily-outnumbered French men-at-arms, tasked with defending the city and awaiting reinforcements, unexpectedly defeated the Anglo-Flemish forces on their own. The allies suffered heavy losses and the French captured their camp intact, taking many warhorses, draft animals and carts, all the tents, huge quantities of supplies and most of the Flemish standards. Edward's campaign of 1340 had begun badly. On the bright side, the loss of several thousand men was bearable, as the survivors, which included most of the precious English longbowmen, eventually rejoined him at Tournai. The defeat had serious strategic consequences. It exposed southern Flanders to the wrath of Philip VI and enabled the French to concentrate their forces against the main army of the coalition in the siege of Tournai.
The opening events of the Breton Civil War took place in 1341 when a French royal army intervened in a dynastic dispute between two claimants to the duchy of Brittany. Brittany was a province of France, but was treated in many ways as an independent principality. When John III, Duke of Brittany, died on 30 April 1341, title to the duchy was claimed by both his niece, Joan of Penthièvre, and his younger half brother, John of Montfort. Joan's claim was through her husband, Charles of Blois, a nephew of the King of France, Philip VI. A complicating factor was the war between France and England which had broken out in 1337. A truce was in effect, which was due to expire in June but was extended to June 1342.
John I of Armagnac, son of Bernard VI and Cecilia Rodez, was Count of Armagnac from 1319 to 1373. In addition to Armagnac he controlled territory in Quercy, Rouergue and Gévaudan. He was the count who initiated the 14th century expansion of the county.
The Hundred Years' War was a conflict between the kingdoms of England and France and a civil war in France during the Late Middle Ages. It emerged from feudal disputes over the Duchy of Aquitaine and was triggered by a claim to the French throne made by Edward III of England. The war grew into a broader military, economic, and political struggle involving factions from across Western Europe, fuelled by emerging nationalism on both sides. The periodisation of the war typically charts it as taking place over 116 years. However, it was an intermittent conflict which was frequently interrupted by external factors, such as the Black Death, and several years of truces.
The siege of Tournai occurred during the Edwardian phase of the Hundred Years' War. The siege began when a coalition of England, Flanders, Hainaut, Brabant and the Holy Roman Empire under the command of King Edward III of England besieged the French city of Tournai. This siege would end in the Truce of Espléchin, marking the end of the Tournaisis campaign of 1340.
The Truce of Espléchin (1340) was a truce between the English and French crowns during the early phases of the Hundred Years' War.
The First Hundred Years' War was a series of conflicts and disputes during the High Middle Ages during which the House of Capet, rulers of the Kingdom of France, fought the House of Plantagenet, rulers of the Kingdom of England. The conflict emerged over the Plantagenet-held Angevin Empire formed by Henry II of England which at its peak covered around half of the territory within France. The ongoing conflict between the two dynasties resulted in the gradual "reconquest" of most of their kingdom by the Capetians, and later, the Plantagenet's attempts to retake what they believed to be their rightful claims in western France.
The Truce of Calais was a truce agreed by King Edward III of England and King Philip VI of France on 28 September 1347, which was mediated by emissaries of Pope Clement VI. The Hundred Years' War had broken out in 1337 and in 1346 Edward had landed with an army in northern France. After inflicting a heavy defeat on Philip and a French army at the Battle of Crécy the English besieged Calais, which fell after 11 months. Both countries were financially and militarily exhausted and two cardinals acting for Pope Clement were able to broker a truce in a series of negotiations outside Calais. This was signed on 28 September to run until 7 July 1348.
The Thiérache campaign, also known as the chevauchée of Edward III of 1339 was the march from Valenciennes, Hainault across Cambrésis, Picardy and Thiérache in northern France by an English army with Flemish, Hainault and Holy Roman Empire allies. It began on 20 September 1339, resulting in the siege of Cambrai and ended with the withdrawal of the English forces on 24 October, 1339, into Brabant. The English army was led by King Edward III, and the French by King Philip VI. It was a campaign during the Hundred Years' War.
The siege of Guînes took place from May to July 1352, when a French army under Geoffrey de Charny unsuccessfully attempted to recapture the French castle at Guînes which had been seized by the English the previous January. The siege was part of the Hundred Years' War and took place during the uneasy and oft-broken truce of Calais.
The Treaty of Guînes was a draft settlement to end the Hundred Years' War, negotiated between England and France and signed at Guînes on 6 April 1354. The war had broken out in 1337 and was further aggravated in 1340 when the English king, Edward III, claimed the French throne. The war went badly for France: the French army was heavily defeated at the Battle of Crécy, and the French town of Calais was besieged and captured. With both sides exhausted, a truce was agreed that, despite being only fitfully observed, was repeatedly renewed.
The Scheldt campaigns of 1339–1340 were a series of manoeuvres by opposing French and Flemish forces during the Hundred Years' War.
The siege of Breteuil was the investment of the Norman town of Breteuil, held by partisans of Charles II, King of Navarre, by French forces between April and about 20 August 1356. It was interrupted on 5 July when a small English army commanded by Henry, Earl of Lancaster, relieved and resupplied it. The French king, John II, attempted to bring Lancaster to battle with the much larger French royal army, but Lancaster marched away and the attempt failed. John then renewed the siege of Breteuil.
English offensives in 1345–1347, during the Hundred Years' War, resulted in repeated defeats of the French, the loss or devastation of much French territory and the capture by the English of the port of Calais. The war had broken out in 1337 and flared up in 1340 when the king of England, Edward III, laid claim to the French crown and campaigned in northern France. There was then a lull in the major hostilities, although much small-scale fighting continued.
