Fredegund or Fredegunda (Latin: Fredegundis; French: Frédégonde; died 8 December 597) was the Queen consort of Chilperic I, the Merovingian Frankish king of Soissons. She served as regent during the minority of her son Chlothar II from 584 until 597.
Fredegund has traditionally been given a very bad reputation, foremost by the accounts of Gregory of Tours, who depicts her as ruthlessly murderous and sadistically cruel, and she is known for the many cruel stories about her, particularly for her long going feud with queen Brunhilda of Austrasia.
Fredegund was born into a low-ranking family but gained power through her association with King Chilperic. Originally a servant of Chilperic's first wife Audovera, Fredegund won Chilperic's affection and persuaded him to put Audovera in a convent and divorce her. Gregory of Tours remarks that Fredegund brought with her a handsome dowry, incurring the immediate affection of King Chilperic.
Chilperic put Fredegund aside and married Galswintha. Galswintha died the same year, probably strangled by Fredegund(c. 568), who succeeded Galswintha as queen. Galswintha's sister, Brunhilda, however, began a feud which lasted more than 40 years.
Gregory of Tours suggests that the Queen had committed adultery. During a dinner with King Guntram, the recently widowed Fredegund rose to leave the table with the excuse that she is pregnant. The announcement surprised the King, as her son Clothar II was born only four months earlier. Gregory of Tours interprets this exchange as a result of Fredegund’s unfaithfulness to her husband.
In 580 AD, an epidemic of dysentery broke out in Gaul, afflicting Fredegund's husband King Chilperic and their two sons, Chlodobert and Dagobert. Believing the plague to be a result of her sins, Fredegund burned a number of tax records she feared were unjust and encouraged Chilperic to do the same. Her sons, however, did not survive the epidemic. Following their funerals, Fredegund made a large donation to churches and the poor to continue to atone for her sins. Another of Fredegund’s sons, Samson, was stricken with a serious illness while the family was under siege in Tournai. According to Gregory, Fredegund feared that she would catch the disease from Samson and cast him away from her, allowing him to die. The King was offended by her actions as the child had not yet been baptized. When Samson survived longer than expected, Fredegund relented and had him baptized according to the King’s wishes.
