What where harald claims to the throne?

Please provide more context! There are many historical figures named Harald, and without more information, it's impossible to determine which one you're referring to.

To help me identify the correct Harald, please provide:

* The approximate time period: When did this Harald live?

* His country or region: Where was he from?

* Any other relevant information: For example, was he a king, a prince, or a commoner?

Once I have more information, I can tell you about Harald's claims to the throne.
