King Knut had four sons and named one of them heir with the great men's consent, but at his death the great men chose Sverker.
The sons were raised at Sverker's court and live there on 1 January 1200, passed over but provided for. Their house's ground is Västergötland: Knut died at the royal manor of Eriksberg in Västergötland ('Errosberch in Vestgocia'), Erik was perhaps born there, and Knut lies in the Cistercian abbey of Varnhem near Skara, which the house patronised. Their father's rule (about 1167-1195/96) left them friends among the Västgöta great men and kin at Sverre's court.
On 1 January 1200 their claim is quiet, not dead.
Who he is
- Name
- Erik Knutsson (born about 1180) and his three brothers, whose names the sources do not give
- Title
- sons of the late king
- Since
- their father's death (autumn 1195 or 8 April 1196)
- Born
- Erik about 1180, perhaps at the royal manor of Eriksberg (en.wikipedia); the brothers not pinned
- Family
- Grandsons of St Erik (Erik Jedvardsson, killed at Uppsala in 1160; fmg gives 1159). Their mother is unknown (sometimes taken to be Cecilia Johansdotter). Their aunt Margareta Eriksdotter is King Sverre's queen in Norway (married 1185). Their uncle Filip Eriksson witnesses a Nydala charter dated about 1200 as 'Philippus frater regis Kanuti' and has a son Holmger (fmg). A sister is reported married to the jarl's son Knut Birgersson (en.wikipedia on Birger Brosa).

en.wikipedia (Knut Eriksson; Eric X); fmg.ac Sweden.
Overlord
King Sverker II
What it holds
- the family manor of Eriksberg in Västergötland (traditionally in Gäsene hundred; not located here)
- patronage of Varnhem Abbey, where King Knut lies (Church map)
- a place at the king's court
How it was acquired
By inheritance from King Knut; their royal claim from their father and grandfather.
Allies and rivals
Sverre of Norway and Queen Margareta (their aunt); the Bjälbo house through the reported marriage; the Västgötar. Rival: Sverker.
How things stand that morning
At Sverker's court, not in arms.
Wealth
The Erik family's farms in Västergötland and perhaps in Uppland (not pinned).
Military
No following of their own is recorded before 1203.
Threats
- Sverker's suspicion once the jarl is gone
What the year holds
What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.
- 1203-1205 (after this year)After Birger Brosa's death they claim the throne, are refused, flee to Norway for the winter of 1204-05 and come back with Birkebeiner help; three fall at Älgarås in Tiveden in November 1205 and Erik escapes to Norway.Depends on: Birger Brosa's death (9 January 1202) and Sverker's refusal Stopped by: a settlement giving them land or office; the jarl living longer
- January 1208 (after this year)Erik returns with Norwegian help and the Folkung lords and beats Sverker at Lena in Västergötland; he is crowned in November 1210 and marries Rikissa of Denmark that year.Depends on: the above
Places of note
- Varnhem Abbey: Cistercian abbey near Skara where King Knut is buried (Church map); shown as the house's seat for want of the located Eriksberg
Where the sources disagree
- Some later writing names the brothers; en.wikipedia says the sources do not. Their ages are disputed (grown men in en.wikipedia, minors in 1196 in de.wikipedia).
Evidence: The sons are known from the king lists and the annals of 1205 and 1208; their estates are known only from Knut's death place and burial.
On the map: Not drawn: Eriksberg is not located with confidence, and the family's other farms are unknown. The marker stands at Varnhem.
