Magnus abdicated his Norwegian throne sometime between 8 and 18 August in 1355. Haakon would then rule as the sole king in the kingdom, though his father continued to exercise control over Norway in the following years, albeit not in name anymore. The first documented event in which Haakon acted as sole king and ruler over his kingdom was on 22 January 1358, when he sent a letter of approval for the privileges in the capital city of Oslo. Norway in 1355 was actually partitioned between Haakon and Magnus: Magnus had specifically requested the territories of Hålogaland and the Norwegian islands in the North Sea at the ratification meeting in Bergen in 1350. Magnus additionally held the territories of Tønsberg and Skien, and he was also the real ruler over the territories of Borgar and most of Bohuslän which were held as personal fiefs by Queen Blanche. Because of this, the realm of Magnus was centered in the south-east, up against the important south-Swedish countryside and the Swedish-held Scania province.
