     French Nobility. Only daughter of Robert II and his first wife Amicie de Courtenay. She married Othon IV de Chalon, Count Palatine of Burgundy in 1291 and gave birth to four children. The first two were Blanche and Jeanne de Bourgogne, the younger two Robert and Jean, did not survive their childhood. After the death of her father, in 1302 in the battle of Kortrijk, she inherited the county of Artois and a year later, after the death of her husband she also inherited parts of the palatine of Burgundy. Due to her intervention her daugther Jeanne was allowed to return to her husbands side in 1315. Mathilde held the young King John I during his christening who died soon after that. She was suspected to be responsiblle for his death, especially because Jeanne became queen due to his death. She founded several abbeys like the Charteuse de Gosnay and the Poor Clares in St-Omer.

     "Mahaut, Countess of Artois - Mahaut of Artois (1268 – 27 November 1329), also known as Mathilda, ruled as Countess of Artois from 1302 to 1329. She was furthermore regent of the County of Burgundy from 1303 to 1315 during the minority of her son, Robert.
Biography
     "She was the eldest child (and only daughter) of Robert II, Count of Artois, and Amicie de Courtenay.[1] Her paternal grandparents were Robert I, Count of Artois, and Matilda of Brabant. Her maternal grandparents were Pierre de Courtenay, Seigneur de Conches, and Perronelle de Joigny.[1] She was the sister of Philip of Artois (1269–1298)[1] and Robert of Artois (born 1271).
     "In 1291, Mahaut married Otto IV, Count of Burgundy.[2] She became the mother of three children, including two girls who married kings of France.
     "Because of the premature death of her brother Philip in 1298, she inherited the County of Artois at her father's death in 1302, rather than her nephew Robert III (her inheritance being based upon proximity of blood).[3] Although he repeatedly challenged the decision, her rights to the county were consistently upheld by the Parlement of Paris and the royal court.[4] She was an able administrator and managed to defeat the many rebellions perpetrated by members of the nobility. Her senior administrator was the Bishop of the Roman Catholic Diocese of Arras, Thierry de Hérisson.[5] Upon her death in 1329, the county was inherited by her daughter Joan II, Countess of Burgundy (d. 1330), the widow of Philip V of France.
In fiction
     "Mahaut is a major character in Les Rois maudits (The Accursed Kings), a series of historical novels by Maurice Druon. Druon describes her as the poisoner of Louis X and his infant son Jean I, who is later poisoned herself the same way by her lady-in-waiting Béatrice d'Hirson, who originally helped with the King's poisoning. Allan Massie wrote in The Wall Street Journal, "Few figures in literature are as terrible as the Countess Mahaut, murderer and maker of kings."[6] She was portrayed by Hélène Duc in the 1972 French miniseries adaptation of the novels,[7] and by Jeanne Moreau in the 2005 remake.[8][9]
Issue
-- Joan II, Countess of Burgundy (1292-1330), married Philip V of France[10]
-- Blanche of Burgundy (1296 ? – 1326), married Charles IV of France[10]
-- Robert, Count of Burgundy (1300–1315).
     "Mahaut's daughters Joan II and Blanche, along with their cousin Margaret of Burgundy, were implicated in the Tour de Nesle affair.

The Chronicle of Guillaume de Nangis names "Ludovicum comitem Ebroiciæ civitatis, Margaretamque reginam Angliæ ac Blancham ducissam Austriæ" as the three children of King Philippe III and his second wife, recording in a later passage the marriage of Blanche and "regis Romanorum Alberti filius Radulfus dux Austriæ" in 1299 "apud Parisius"[745]. [The Annals of Worcester record that Edward I King of England was absorbed by “immoderatus amor” for “mulieris Gallicæ et neptis propriæ” in 1294[746]. The source does not record the person to whom it refers. The editor of the edition consulted suggests in a footnote that she was Blanche, daughter of King Philippe III, citing “Bart. Cott. p. 232”.] Her Austrian marriage was arranged to confirm King Albrecht's new alliance with France[747]. The Continuatio of the Chronicle of Guillaume de Nangis records the death in Mar 1306 of "ducissa Austriæ Blancha, regis Franciæ soror ex patre...cum filio suo unico", poisoned[748]. The Grandes Chroniques de France record the death “empoisonnée par ledit duc, si comme l’en disoit...ou moys de mars” of “Blanche duchesse d’Austrie seur du roy de par son pere”[749]. The necrology of Königsfelden records the death "XIV Kal Apr" of "domina Blanka" without giving further details to identify her[750]. The necrology of Feldbach records the death "XIV Kal Apr" of "Blanka relicta Ruodolfi quondam regis Boemie"[751], although this implies, wrongly it appears, that her husband predeceased her. The necrology of Kloster Neuburg records the death "XIV Kal Apr 1305" of "Blanka filia regis Francie, ducissa Austrie et Styrie"[752]. The necrology of Minoritenkirche, Vienna records the death "XIV Kal 1305" of "Blanka ducissa Austrie filia Philippi regis Francie consors Rudolfi ducis Austrie hic sepulta"[753]. The necrology of Rein records the death "IV Non Mar" of "Planca ducissa Austrie et Stirie"[754], although this date is inconsistent with other sources.

     “Jean I de Dampierre, comte de Namur, was born about October 1267, the son of Guy de Dampierre, Graaf van Vlaanderen, Graaf van Namen, and his second wife Isabelle de Luxembourg, heiress of Namur.
     “In March 1297 his father gave him the rule over the county of Namur, though his father retained the title of Count of Namur until his death in 1305. Jean nevertheless used the title over those years. From 1296 to 1298 he was held captive in Paris with his father. In 1300 he concluded a treaty with the various towns of Liège which placed them under his protection. His father was imprisoned again in Paris, and with his brother Guy, count of Zeeland, Jean fought against the French, defeating them at the Battle of Kortrijk (Courtrai) on 11 July 1302. However he was defeated in 1304 at Mons-en-Puelle. Peace with France was signed in 1307.
     “In 1307 he paid homage to Willem III 'the Good', Graaf van Holland en Henegouwen, for the county of Namur and the lordship of Poilvache. Also in that year he married Marguerite de Clermont, daughter of Robert de France, comte de Clermont-en-Beauvaisis, and Beatrice de Bourgogne, heiress of Bourbon. The marriage did not result in progeny, Marguerite dying in January 1309.
     “In 1308 Charles, comte de Valois, claimed the county of Namur as husband of Catherine de Courtenay, granddaughter of Baudouin II de Courtenay, emperor of Constantinople, former count of Namur. However Philippe 'le Bel', king of France, ruled in favour of Jean.
     “On 6 May 1309 in Paris, Jean married Marie d'Artois, daughter of Philippe d'Artois, sire de Conches, de Nonancourt, de Domfront, and Blanche de Bretagne. Of their eleven children, Guillaume and Blanche would have progeny.
     “While Jean accompanied Emperor Heinrich VII to Italy, the people revolted against his wife Marie d'Artois over excessive taxes. The revolt was suppressed in 1313, with the assistance of Arnold IV, Graf von Looz, Chiny und Agimont. In 1314 the emperor gave Jean the lordship of Cambrai. After he took possession he dismissed the officers of the bishop of Cambrai; this and his many insults against the Church led to his excommunication until 1317. He was at war against the bishop of Liège, Adolphe de La Marck, from 1318 to 1322.
     “Jean died on 31 January 1330.”.⁶
