Girart de Roussillon

Girart de Roussillon, also called Girard, Gérard II, Gyrart de Vienne, and Girart de Fraite, (c. 810–877/879?) was a Burgundian chief who became Count of Paris in 837, and embraced the cause of Lothair I against Charles the Bald. He was a son of Leuthard I, Count of Fézensac and of Paris, and his wife Grimildis.

Girart is not described as being from Roussillon in authentic historical sources. The placename in his title is derived from a castle he built on Mont Lassois, near Vix and Châtillon-sur-Seine (Côte-d'Or).

Girart de Roussillon also is an epic figure in the cycle of Carolingian romances, collectively known as the Matter of France. In the genealogy of the cycle’s legendary heroes, Girart is a son of Doon de Mayence and appears in the various irreconcilable events.

Girart fought at the Battle of Fontenay in 841, and doubtless followed Lothair I, his future brother-in-law, to Aix-en-Provence. In 843, he married Bertha, daughter of Hugh of Tours and sister of Ermengarde of Tours, Lothair's wife.

In 855, Girart became governor of Provence for Lothair's son Charles, nominal king of Provence. His wife Bertha defended Vienne unsuccessfully against Charles the Bald in 870. Girart, who had perhaps aspired to be the titular ruler of the northern part of Provence, continued to administer it under Lothair II until that prince's death in 869. He retired with his wife to Avignon where he died probably in 877, certainly before 879.
