The second man of the kingdom and in practice its steadying hand.
Jarl since about 1174, Birger led the levy and the great men for King Knut and, by most accounts, arranged Sverker's peaceful election in 1196. His wife was a Norwegian king's daughter, and he gave refuge to the Norwegian pretenders Eystein Møyla and Sverre, her kinsmen, in the 1170s (en.wikipedia; by Sverris saga he refused Sverre help when Sverre came to him in Östergötland at Christmas 1176); his son Philip, Sverre's cousin through Brigida, now serves Sverre as a jarl. Abroad he also backed the Scanian rebels against Valdemar I and Absalon in 1180-82 (Dansk biografisk leksikon, as cited on the dkz sheet), yet he stands beside the Danish-raised Sverker now.
He seems to have kept Sweden out of the civil wars that tore Denmark and Norway. The family's oldest known manor is Bjälbo in Östergötland near Skänninge, and his estates lay in Östergötland, Närke, Värmland and Södermanland; he and Brigida were great givers to Riseberga Abbey in Närke, where she ended her days.
Who he is
- Name
- Birger Brosa (Birger Bengtsson)
- Title
- jarl of the Swedes and the Götar (Latin dux Sweorum et Guttorum)
- Since
- about 1174, under King Knut Eriksson (en.wikipedia); kept the office under Sverker
- Born

- Family
- Son of Bengt Snivil, of the Bjälbo house that goes back to Folke the Fat, jarl about 1100. Wife: Brigida Haraldsdotter, daughter of King Harald Gille of Norway, earlier the wife of the pretender Magnus Henriksson (king at Uppsala 1160-61). Sons: Philip (Filippus), jarl in Norway in King Sverre's service and 'one of his most loyal supporters', who dies in 1200 (day not pinned); Knut, later jarl, reportedly married to a daughter of King Knut Eriksson (killed 1208 at Lena or 1210 at Gestilren); Folke, later jarl, killed at Gestilren in 1210 (de.wikipedia calls Folke Birger's brother instead); Magnus, named by Snorri. Daughters: Ingegerd, who marries King Sverker in 1200; Kristina and Margareta. Brother: Magnus Minnesköld, his younger brother by a medieval genealogy (en.wikipedia), who lives at Bjälbo (Magnus Minnesköld).
- Confidence
- high
en.wikipedia (Birger Brosa; House of Bjälbo; Magnus Minnesköld; Eskil Magnusson); de.wikipedia (Sverker II).
Overlord
King Sverker II
What it holds
- the jarl's office: the levy fleet and the jarl's share of royal dues, including part of Gotland's tribute (Guta saga)
- Bjälbo near Skänninge in Östergötland, the house's oldest known manor, where his brother Magnus lives (en.wikipedia)
- estates in Östergötland, Närke, Värmland and Södermanland (en.wikipedia; not located; Närke and Södermanland are on the swn sheet)
- patronage of Riseberga Abbey in Närke (swn sheet)
How it was acquired
Bjälbo by inheritance; the jarl's office from King Knut about 1174.
Allies and rivals
King Sverker (soon his son-in-law); King Sverre of Norway (his wife's kinsman, his son's lord); King Knut's sons (his son Knut reportedly married their sister). No open rival is recorded; the Danish court may remember his help to the Scanian rebels of 1180-82.
How things stand that morning
At the height of his power and the hinge of the realm: the king's partner, the Erik house's friend and Sverre's ally at once.
Wealth
The Bjälbo estates on the Östergötland plain, lands across four provinces, the jarl's dues.
Military
Leader of the ledung and of the great men's retinues; Bjälbo's fortified church tower is of uncertain date and is not claimed for 1200.
Threats
- his age (he dies on 9 January 1202)
- the loss of Philip in Norway
- the question who succeeds him as jarl
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.
In 1200
- 1200 (en.wikipedia)His daughter Ingegerd marries King Sverker.Depends on: Queen Benedikta's death Stopped by: a breach with the king
- 1200, day not pinned (en.wikipedia)His son Philip, Sverre's jarl, dies in Norway.Depends on: the Norwegian war Stopped by: his circumstances changing
Later, on the likely course
- 9 January 1202 (after this year)Birger Brosa dies; a son of his becomes jarl and dies soon after (de.wikipedia); Sverker gives the title to his infant son Johan.Depends on: natural death
Places of note
- Bjälbo: the house's oldest known manor
- Skänninge: the market town beside Bjälbo
Where the sources disagree
- de.wikipedia makes Folke, the jarl killed at Gestilren in 1210, Birger's brother and the father of Sune Folkesson; en.wikipedia makes him Birger's son. Not settled here.
Evidence: The jarl and his family are named in Sverris saga, Snorri and charters; his estates are named by province only.
On the map: Only the seat is drawn; the estates in Värmland, Närke and Södermanland are known by province only.
