That's what Viking literally translates to.

There were some quasi racial elements, the idea of "races of man" is mentioned in the Sagas and such but it wasn't really the same. More tribal, less about skin tone but also the Vikings didn't really have contact with other skin tones unless they were one of the groups raiding the Mediterranean or Vinland which was rare.

Still proto-fascists balls deep in might makes right with a chattel slave economy though.

Pretty sure pirates were the real life pirates

...do you think pirates weren't real? Hell, they're real now. The reason piracy isn't much more widespread isn't because humanity has progressed, it's because the navies of NATO powers and others constantly patrol the oceans to protect their economies' bottom lines.
