Margaret I of Denmark
Eric's father attempted to consolidate his position as King of Sweden in 1364 and again in 1386. Queen Margaret I of Denmark intervened and defeated Albert in the battle of Åsle, in the vicinity of Falköping, in 1389. Albert and Eric were captured during this battle. They were released in 1395 after three years of negotiations involving Hinrich Westhof and Johann Niebur, the mayors of Lübeck.
