Ulf Fase

[2][3] In 1222, the rival dynasty's young heir, King Erik Eriksson ascended the throne at the age of 6.

His minority meant that Jarl Ulf gained more importance along with Knut Långe.

There are clear records to show that Ulf Fase had the right to mint money, an otherwise exclusively royal prerogative.

Sources do not reveal whether Ulf was already dead at that time, or if alive, what was his role in the revolt.

[7][8] Ulf Fase left one well-attested son, Karl Ulfsson [sv] who had bad relations with Birger Jarl.
