Eric Magnusson

Erik Magnusson ( – 1318) was a Swedish prince and Duke of Södermanland, the second son of King Magnus Ladulås. His duchy consisted of large parts of Sweden, as well as smaller parts of Norway and Denmark. He had a troubled relationship with his brother, King Birger Magnusson, resulting in several uprisings. His son, Magnus, became king of Sweden and Norway. The Erik's Chronicle, the oldest Swedish chronicle, is named after him.

Background

Erik was born around 1282, the second son of King Magnus Ladulås of Sweden and his queen consort, Helvig of Holstein. In 1284, as his elder brother Birger was designated as the future king, Erik was granted the title of duke, receiving Södermanland and part of Uppland as his fief. However, it was not until Birger's coronation in 1302 that Erik formally assumed his duties as duke.
