The Duchy of Brittany was a medieval feudal state that existed between approximately 939 and 1547. Its territory covered the northwestern peninsula of Europe, bordered by the Atlantic Ocean to the west, and the English Channel to the north. It was also less definitively bordered by the river Loire to the south, and Normandy, and other French provinces, to the east. The Duchy was established after the expulsion of Viking armies from the region around 939. The Duchy, in the 10th and 11th centuries, was politically unstable, with the dukes holding only limited power outside their own personal lands. The Duchy had mixed relationships with the neighbouring Duchy of Normandy, sometimes allying itself with Normandy, and at other times, such as the Breton–Norman War, entering into open conflict.
The Combat of the Thirty, occurring on 26 March 1351, was an episode in the Breton War of Succession fought to determine who would rule the Duchy of Brittany. It was an arranged fight between selected combatants from both sides of the conflict, fought at a site midway between the Breton castles of Josselin and Ploërmel among 30 champions, knights, and squires on each side. The challenge was issued by Jean de Beaumanoir, a captain of Charles of Blois supported by King Philip VI of France, to Robert Bemborough, a captain of Jean de Montfort supported by Edward III of England.
Joan of Penthièvre reigned as Duchess of Brittany together with her husband, Charles of Blois, between 1341 and 1364. Her ducal claims were contested by the House of Montfort, which prevailed only after an extensive civil war, the War of the Breton Succession. After the war, Joan remained titular Duchess of Brittany to her death. She was Countess of Penthièvre in her own right throughout her life.
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.
John of Montfort, sometimes known as John IV of Brittany, and 6th Earl of Richmond from 1341 to his death. He was the son of Arthur II, Duke of Brittany and his second wife, Yolande de Dreux. He contested the inheritance of the Duchy of Brittany by his niece, Joan of Penthièvre, which led to the War of the Breton Succession, which in turn evolved into being part of the Hundred Years' War between England and France. John's patron in his quest was King Edward III of England. He died in 1345, 19 years before the end of the war, and the victory of his son John IV over Joan of Penthièvre and her husband, Charles of Blois.
John IV the Conqueror KG, was Duke of Brittany and Count of Montfort from 1345 until his death and 7th Earl of Richmond from 1372 until his death.
Joanna of Flanders was Duchess of Brittany by her marriage to John of Montfort. Much of her life was taken up in defence of the rights of her husband and, later, son to the dukedom, which was challenged by the House of Blois during the War of the Breton Succession. Known for her fiery personality, Joanna led the Montfortist cause after her husband had been captured, and began the fight-back, showing considerable skill as a military leader.
The first phase of the Hundred Years' War between France and England 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.
Olivier V de Clisson, nicknamed "The Butcher", was a Breton soldier, the son of Olivier IV de Clisson. His father had been put to death by the French in 1343 on the suspicion of having willingly given up the city of Vannes to the English.
The Battle of Saint-Pol-de-Léon was a minor action during the Breton War of Succession and thus part of the larger Hundred Years War. The battle was fought in June 1346 and marked a minor turning point in the fortunes of the Montfortists and their English allies in Brittany following several setbacks including the imprisonment and subsequent death of their leader, John of Montfort.
The Battle of Mauron was fought in 1352 in Brittany during the Breton War of Succession between an Anglo-Breton force supporting the claim of Jean de Montfort and a Franco-Breton force supporting the claim of Charles de Blois. The Anglo-Bretons were victorious. The battle took place in the context of the Hundred Years War.
The Battle of Morlaix was fought in Morlaix on 30 September 1342 between the Anglo-Breton and Franco-Breton forces in Brittany. The Anglo-Breton under English command besieged the town, but a Franco-Breton relief force arrived. The English constructed a strong defensive position. After repeated attacks, the French forced the English to retreat into the woods, and the French force then withdrew.
The House of Montfort-Brittany was a Breton-French noble family, which reigned in the Duchy of Brittany from 1365 to 1514. It was a cadet branch of the House of Dreux; it was thus ultimately part of the Capetian dynasty. It should not be confused with the older House of Montfort which ruled as Counts of Montfort-l'Amaury.
Jean, or Jehan de Beaumanoir, marshal of Brittany for Charles of Blois, and captain of Josselin, is remembered for his share in the famous Combat of the Thirty during the War of Breton Succession (1341–1364) between the warring parties of competing claimants for the Dukedom.
The Battle of Champtoceaux, often called the Battle of l'Humeau, was the opening action of the 23-year-long War of the Breton Succession, a dynastic conflict in the Sovereign Duchy of Brittany which became inevitably embroiled in the Hundred Years War between England and France. This battle should have decided the war at a stroke, as John of Montfort, the leader of one faction, was made prisoner. However his wife, Joanna of Flanders, and young son John escaped imprisonment. Their escape and continued support from his ally, England, allowed continued resistance to flourish and eventually turn the tide.
The Château de Brest is a castle in Brest, Finistère, France. The oldest monument in the town, it is located at the mouth of the river Penfeld at the heart of the roadstead of Brest, one of the largest roadsteads in the world. From the Roman castellum to Vauban's citadel, the site has over 1700 years of history, holding right up to the present day its original role as a military fortress and a strategic location of the highest importance. It is thus the oldest castle in the world still in use, and was classified as a monument historique on 21 March 1923.
Jeanne de Clisson (1300–1359), also known as Jeanne de Belleville and the Lioness of Brittany, was a French/Breton noblewoman who became a privateer to avenge her husband after he was executed for treason by King Philip VI of France. She crossed the English Channel targeting French ships and often slaughtering their crew. It was her practice to leave at least one sailor alive to carry her message of vengeance.
The French–Breton War lasted from 1487 to 1491. The cause of this war was the approaching death of the Breton Duke Francis II of Brittany, who had no clear successor. If not resolved, this meant a resumption of issues from a previous War of the Breton Succession (1341–1364), which had rival claimants allying with England or France, resulting in an ambiguous peace treaty that failed to prevent future succession disputes.
The sieges of Vannes of 1342 were a series of four sieges of the town of Vannes that occurred throughout 1342. Two rival claimants to the Duchy of Brittany, John of Montfort and Charles of Blois, competed for Vannes throughout this civil war from 1341 to 1365. The successive sieges ruined Vannes and its surrounding countryside. Vannes was eventually sold off in a truce between England and France, signed in January 1343 in Malestroit. Saved by an appeal of Pope Clement VI, Vannes remained in the hands of its own rulers, but ultimately resided under English control from September 1343 till the end of the war in 1365.
Amaury de Clisson (1304–1347), was a Breton knight who became the chief emissary for Jeanne de Penthièvre to the court of Edward III of England.
