Joan the Lame

Joan of Burgundy (; c. 1293 – 12 December 1349), also known as Joan the Lame (), was Queen of France as the first wife of King Philip VI. Joan ruled as regent while her husband fought on military campaigns during the Hundred Years' War: 1340, 1345-1346 and 1347.
Early life.
Joan was the daughter of Duke Robert II of Burgundy, and Agnes of France. Her older sister, Margaret, was the first wife of King Louis X of France. Joan married Philip of Valois, Louis's cousin, in July 1313. From 1314 to 1328, they were count and countess of Maine; from 1325, they were also Count and Countess of Valois and Anjou.
Queenship.
King Philip IV's sons, Louis X, Philip V, and Charles IV, left no surviving sons, leading to the accession of Joan's husband to the French throne in 1328. 
The Hundred Years' War ensued in 1337, with Edward III of England, a nephew of Louis X, claiming the French crown. 
In a document issued by Philip VI at Clermont-en-Beauvaisis in August 1338, queen Joan was invested with power of attorney to manage the affairs of state whenever circumstances made it necessary. She was explicitly allowed to manage the finances of the state, to make verdicts and issue pardons and all powers included in the king's duties except managing warfare. This power of attorney was to be used whenever the king was abscent, but it technically gave the queen the potential status of a co-ruler, and one reason suggested to Philip's great trust of Joan was his great distrust of his courtiers. Intelligent and strong-willed, Joan proved a capable regent while her husband fought on military campaigns during the war. 
Joan reportedly favored people from her own home territory of Burgundy, a policy followed by her husband and her son, thus attracting animosity from the North Western nobility at court.
Her political activity attracted controversy to both her and her husband, which was accentuated by her deformity (which was considered by some to be a mark of evil), and she became known as "la male royne boiteuse" ("the lame evil Queen"). One chronicler described her as a danger to her enemies in court: 
Joan was considered to be a scholar and a bibliophile. She sent her son, John, manuscripts to read, and commanded the translation of several important contemporary works into vernacular French, including the "Miroir historial" of Vincent de Beauvais (c.1333) and the "Jeu d'échecs moralisés" of Jacques de Cessoles (c.1347), a task carried out by Jean de Vignay.
Death.
Joan died of the plague 12 December 1349. She was buried in the Basilica of Saint Denis; her tomb, built by her grandson Charles V, was destroyed during the French Revolution.
Family, children and descent.
Her children with Philip VI were:
In 1361, Joan's grandnephew, Philip I of Burgundy, last duke of Burgundy of the first Capetian House of Burgundy, died without issue. The rightful heir to Burgundy was unclear: King Charles II of Navarre, grandson of Joan's elder sister Margaret, was the heir according to primogeniture, but John II of France (Joan's son) claimed to be the heir according to proximity of blood. In the end, John won.
In fiction.
Joan is a character in "Les Rois maudits" ("The Accursed Kings"), a series of French historical novels by Maurice Druon. She was portrayed by Ghislaine Porret in the 1972 French miniseries adaptation of the series.
