Erik of Pomerania, born in the year one thousand three hundred eighty-one, was a significant figure in Scandinavian history, known for his role as a monarch during a tumultuous period. He ascended to power as the ruler of the Kalmar Union in one thousand three hundred ninety-six, a position he held until one thousand four hundred thirty-nine. Initially, he shared the throne with his great-aunt, Margaret I, until her passing in one thousand four hundred twelve.
Throughout his reign, Erik was recognized by various titles across the kingdoms he governed. He was known as Erik III in Norway from one thousand three hundred eighty-nine to one thousand four hundred forty-two, Erik VII in Denmark from one thousand three hundred ninety-six to one thousand four hundred thirty-nine, and Erik XIII in Sweden during two separate terms, from one thousand three hundred ninety-six to one thousand four hundred thirty-four and again from one thousand four hundred thirty-six to one thousand four hundred thirty-nine.
Despite his initial successes, Erik's reign was marred by challenges that ultimately led to his deposition from all three kingdoms of the Kalmar Union. However, in one thousand four hundred forty-nine, he inherited a portion of the Duchy of Pomerania, where he ruled as duke until his death in one thousand four hundred fifty-nine. His epithet of Pomerania was often used pejoratively, suggesting that he was an outsider in the Scandinavian realm.
