Siegfried de Guînes (died c. 965) (Latin: Sifridus Dacus), also known as Siegfried "the Dane" (Sifridus de Dachia), Sigifrid, or Sigifroy,[1] was a Viking who controlled the area around Guînes in 928, although he never seemed to be formally designated as Count even though he is known as such.[2] He is the founder of the line of the Counts of Guînes.
The lands of Guînes originally belonged to the Abbey of Sithiu, which later became the Abbey of Saint-Bertin in Saint-Omer, France. In 877, Charles the Bald had confirmed the abbey's possessions of these lands, which were afterwards obtained by the County of Flanders.
There are two hypotheses regarding how Siegfried came to and took possession of Guînes:
There is also a legend that around 965 Siegfried fell in love with Elftrude, daughter of Arnulf I, Count of Flanders, and Elftrude became pregnant. That same year, Siegfried died and Elftrude had a posthumous son, baptised as Ardolf (Ardolph), who became the first Count of Guînes.[2]
Although this has been accepted by a number of historians, such as Siegfried Rösch,[4] there are no contemporary records of these events, as the earliest recorded history was written 200 years later. Thus, his existence is obscure. He is mentioned for the first time at the beginning of the 13th century in the chronicle of the Counts of Guînes by Lambert of Ardres as the progenitor of the Count's house.
Lambert puts Siegfried's arrival in Guînes around 928 and puts his death in 965 or 966, shortly after the death of Arnulf I of Flanders.[5]
