MAGNUS II (Smek), age three at his accession and, until 1333, ruler under the regency of his mother. He was a weak and ineffectual ruler, but through his mother succeeded (1319) to the Norwegian crown and, during the troubled period in Denmark, managed to acquire, temporarily, Scandinavia, Halland, and Bleking (given up again in 1360, to Waldemar IV). His long minority and his reliance on unworthy favorites led to a striking weakening of the royal power and an equally striking rise of the aristocratic party (first Riksdag, including burghers, 1359).
