Mahaut of Artois
Mahaut of Artois (1268–1329), also called Mathilda, was the daughter of Count Robert II of Artois and in 1291 married Otto IV, Count of Burgundy. On her father's death in 1302 she inherited Artois by proximity of blood and ruled it for twenty-seven years against the claims of her nephew Robert III.
The Parlement of Paris repeatedly upheld her rights, and she crushed noble revolts. She governed the County of Burgundy as regent for her daughter Joan II from 1303 to 1315.
Her daughters Joan and Blanche married kings Philip V and Charles IV of France, and in 1316 she was accused of poisoning Louis X. She died on 27 November 1329.
