After destroying the Bagler fleet at Strindsjøen on 18 June 1199, Sverre took Viken in hand and settled into winter quarters at Oslo (en.wikipedia; snl.no).
He had squeezed Viken through 1198-99, sending several great levies east to take war-taxes, and the countryside hates him. On 1 January 1200 he holds Oslo with his host, which snl.no, following the saga, puts at about 3,000 men; his son Sigurd Lavard is with him. His men hold the Viken towns and Ranrike, but no officer of his there is named in the sources checked.
The Bagler are coming back from Denmark (Reidar strikes at Oslo at Yule), and in the new year the farmers from Svinesund to Telemark and the townsmen of Tunsberg gather to drive him out. He beats them at Oslo on 6 March 1200 and sails for Bergen in late March.

How it was acquired
Conquest after Strindsjøen, autumn 1199 (en.wikipedia).
Allies and rivals
With him: the Birkebeiner hird, his son Sigurd Lavard. Against him: the Bagler, the exiled Church, the farmers of Viken and Telemark, the townsmen of Tunsberg; Denmark shelters his enemies.
How things stand that morning
In Oslo with his host for the winter; master of Oslo and the fjord, hated in the countryside. Rome's interdict on the lands that support him (1198) and his excommunication stand.
Wealth
War-taxes taken from Viken (snl.no: heavy contributions, strongly resisted); the royal estates.
Military
His host at Oslo (about 3,000 by the saga's count, per snl.no) and ships. No castle at Oslo: his castles (both called Sverresborg) are at Nidaros and Bergen (now sheet).
Threats
- The farmers' rising (January to March 1200).
- The Bagler fleet behind him on the coast.
- Supplies for a host wintering among hostile farmers.
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
- Yule 1199-1200Reidar Sendemann's Bagler attack Oslo (snl.no).Depends on: The Bagler return. Stopped by: His guard.
- 6 March 1200Beats the farmers' army at Oslo, partly in Bjørvika, one band at a time (Koht; en.wikipedia; snl.no Bjørvika). Sigurd Lavard is in the fight.Depends on: The farmers coming on without one commander. Stopped by: The Bagler fleet joining the farmers.
- late March 1200Sails back to Bergen (en.wikipedia).Depends on: Victory at Oslo. Stopped by: Defeat.
- 1200 (date not pinned)His son Sigurd Lavard dies (snl.no; now sheet).
Later, on the likely course
- spring 1201 to 25 January 1202Comes east again with the leidang, takes war-taxes on both sides of the Oslofjord and besieges Reidar on Berget at Tunsberg from September 1201 until the surrender (en.wikipedia).Depends on: The Bagler holding Tunsberg. Stopped by: A settlement.
- 9 March 1202Dies at Bergen (en.wikipedia).
Places of note
- Bjørvika: Where he fought the farmers in March 1200 (snl.no).
- Hovedøya: The Cistercian abbey island from which he attacked Oslo on 25 July 1197 (en.wikipedia History of Oslo).
Where the sources disagree
- The norway realm record belongs to the now sheet; this record covers only his presence in Viken that winter.
Evidence: Sverris saga as summarised by en.wikipedia and snl.no; the March battle is dated in Koht's translation.
On the map: Only Oslo is drawn as his; the modern Oslo municipality includes the Nordmarka forest.
