That, I can agree with. XD

I honestly think the fact that this is being debated nearly to this extent, just shows that Harkon's Backstory had little no thought put into it.

They might've just thrown it in there as a Dracula reference. Since according to legend, before he became a Vampire he was the king of Hungary.
