What is known is that Erik was the Duke of Uppsala and the King of Anglia. Erik issued a series of laws to promote order and solidarity in the expanding kingdom. He was killed by one of his rivals as he left church in Uppsala. In later centuries he became a focus of veneration and Anglian, and later Aloian, nationalism. The city of Erikskrona, Svea, is named for him, as well as numerous churches and other things throughout Aloia.
