Birger was only ten years old when his father died, at which time Torgils Knutsson was the most influential statesman in Sweden. In 1293, Torgils Knutsson led the Swedes to a victory which won a part of western Karelia. This expedition has traditionally been dubbed as the Third Swedish Crusade. When Torgils Knutsson returned from leading the crusade in Finland, a feud had developed between the brothers. Torgils Knutsson supported King Birger. Birger came of age when there was a conflict within the Church of Sweden over interpretation of the Privileges of 1280, which had been the cost of the support of the Church for his father's usurpation. The king's brothers Erik Magnusson, Duke of Södermanland and Valdemar Magnusson, Duke of Finland took advantage of this conflict. Duke Eric tried to establish an independent kingdom around Bohuslän, which he had received as part of his marriage to the Norwegian princess Ingeborg, and Halland at the boundary between Sweden, Norway and Denmark. A civil war broke out, but by 1306 emotions had cooled to the point where the dukes acknowledged the son of Birger, Magnus Birgersson, as the successor to the throne. Torkel Knutsson, who was Duke Valdemar's father-in-law, was executed in 1306 as a token of reconciliation between King Birger and his brothers. The same year, in an event known as the Håtuna games, Birger was taken captive by his brothers on the Håtunaroyal estate in Uppland and taken as prisoner to Nyköping Castle. In 1308, Eric and Valdemar were forced by the Danish king to release King Birger, but they did so under humiliating conditions. When King Birger was free, he sought aid in Denmark, and the strife began anew. Birger remained king in name, but had to give up the Royal Domain, exchanging it for eastern Uppland, Närke, his brother Erik's former Duchy Södermanland, Östergötland, Gotland and the Castle of Viborg. In 1312, Duke Eric married Ingeborg of Norway, daughter of King Haakon V of Norway in a double wedding in Oslo. At the same time, Eric's brother Duke Valdemar married Ingeborg Eriksdottir of Norway, the daughter of King Eric II of Norway. Duke Erik also held Bohuslän from Norway as well as northern Halland and was creating a separate kingdom centered on Göta älv. In 1317 however, Birger captured his brothers during the Nyköping Banquet, which led to their death. According to Eric's Chronicle, the dukes were starved to death in a cellar of Nyköping Castle. Birger was ousted by his brothers' supporters in 1318 and eventually went into exile under his brother-in-law King Eric VI of Denmark, taking the Royal Archives with him. His 18-year-old son Magnus had arrived that year with Danish troops to save Birger but an army under Canute Porse defeated them at Söderköping, practically putting an end to the conflict. Birger first fled to Gotland and left Magnus to defend the important Stegeborg Castle. Magnus was captured there only to be executed in Stockholm in 1320, with a younger brother Eric having died the year before and ex-king Birger dying in Denmark the year after. In 1319, the three-year-old son of Duke Erik, King Magnus VII of Norway, had then already been hailed King of Sweden after the short regency of his mother Duchess Ingeborg.
