Margaret of Burgundy, Queen of France

Margaret of Burgundy (French: Marguerite; 1290 – 14 August 1315) was Queen of France and Navarre as the first wife King Louis X and I.

Margaret was a princess of the ducal House of Burgundy, a branch of the Capetian dynasty. She was the eldest daughter of Robert II, Duke of Burgundy (1248–1306) and Agnes of France (1260–1327), the youngest daughter of Louis IX of France and Margaret of Provence.

In 1305, Margaret married her first cousin once removed, Louis I, King of Navarre, who in November 1314 ascended to the French throne as Louis X of France. They had one daughter, Joan (born 1312, died 1349).

Early in 1314, Margaret was allegedly caught in an act of adultery in the Tour de Nesle Affair. Her sister-in-law Isabella of France was a witness against her, and Margaret was imprisoned for the last two years of her life, along with her sister-in-law Blanche of Burgundy. Margaret was confined at Château Gaillard and after poor treatment caught a cold and died.

Margaret's daughter, Joan, later became queen regnant of Navarre as Joan II (1311–1349). Her paternity was under doubt because of her mother's alleged adultery.

In 1361, Margaret's succession rights became important in the premature death of Philip I, Duke of Burgundy (her grandnephew), since the closest Burgundian heirs were descendants of Margaret and of her sister, Joan the Lame. Margaret's grandson and heir Charles II of Navarre claimed the duchy on the basis of primogeniture, but Joan the Lame's son John II of France on the basis of proximity, being one generation closer to the Burgundian dukes. The case was ruled in favour of John, who became Duke of Burgundy, later bestowing the Duchy upon his son, Philip the Bold.

Margaret is portrayed in La Roi en fer and La Reine étranglée, two 1955 novels in Maurice Druon's Les Rois maudits (The Accursed Kings) series of historical novels. She was played by Muriel Baptiste (fr) in the 1972 French miniseries adaptation of the series, and by Hélène Fillières in the 2005 adaptation.
