Sven Aggesen

Svend Aggesen (or "Sven"; also known as Aggessøn, Aggesøn or Aagesen, in Latin Sveno Aggonis; born around 1140 to 1150, death unknown) is the author of Brevis historia regum Dacie, one of the first attempts to write a coherent history of Denmark covering the period 300AD-1185AD. Only the Chronicon Roskildense may precede Aggesen's efforts.

Family

Sven Aggesen was born into a magnate family which had several well-known members.

The earliest known family member that we know of with some certainty is Svend's great-grandfather, Thrugot, who was married to Thorgunna, daughter of Vagn Aggesøn, a grandson of the legendary Palne Toke. Thrugot and Thorgunna had two sons, Sven and Vagn.

Sven Thrugotsøn (or Thorgunnasøn) had four sons. One, probably the eldest, Asser, was the first Archbishop of Lund (1104–1137) and also the first Archbishop of Scandinavia. Another, probably the youngest, Sven, was a canon in Lund, later in Viborg and even later (1132), bishop in Viborg. The third, Eskil, we know little about, but the last, Christiern Svensøn, is Svend Aagesen’s grandfather.
