Ynglinga saga
Halfdan Whiteshanks (Old Norse: "Hálfdan hvítbeinn") was a semi-historical petty king in Norway, described in the "Ynglinga saga". The following description is based on the account in Ynglinga saga, written in the 1220s by Snorri Sturluson. The historicity of the kings described in that saga is generally not accepted by modern historians.
