King in Svitjod from 280 until killed by his brother in the year 306 AD. King Alf was very jealous of his brother Yngve. Alf’s wife taunted him by making flattering remarks about Yngve, and preferred the company of her brother-in-law to that of her husband. One night after a drinking bout where the guests were so drunk they did not see the King enter the room, he went to the high seat where his wife sat with Yngve. Alf stabbed Yngve to death, but not before Alf returned the favor and both fell dead.
