Technically speaking, the Normans were Norsemen.

"Viking" is an activity, or an occupation. (See Here)

...there were no such people as "the Vikings"; a man might go in viking (to calque a little Old Norse) one year, and the next year return to the same location as a peaceful trader. The implication, then, is that "viking" is the name of an activity, even if not literally derived qua gerund from a verb.
