The brothers Bengt Jönsson Oxenstierna and Nils Jönsson Oxenstierna are selected to serve as co-regents of Sweden at the death, without a direct heir, of Christopher of Bavaria in January 1448.

The Regency period ends with the election of former regent-administrator Karl Knutsson Bonde as King Charles VIII of Sweden, with the intent to reestablish the Kalmar Union under a Swedish crown.

Installed as king of Sweden on June 20, Charles is hailed on June 28 as the new monarch at the Stones of Mora, not far from Uppsala, mostly due to his own military troops being present at the place, against the wishes of the regents.
