Is Magnus a ‘Viking’ name?

It was adopted by Scandinavians during the Viking Age.

Magnus is a Latin name meaning ‘the great one’. It originates from the Roman world (e.g. Gnaeus Pompeius Magnus).

It is not Germanic, Old Norse or pre-christian.

How did the name come to Scandinavia?

A key turning point was Magnus I. of Norway (Magnus the Good; 1024-1047).

According to tradition, he was named after Charlemagne, called Carolus Magnus in Latin.

From this point on Magnus spread among christian Scandinavian elites and became a prestigious royal name, but it did not replace classic Old Norse names such as Þórsteinn, Hákon, Bjǫrn, Sigurðr, etc.

So is Magnus a ‘Viking name’?

That depends on what you mean:

Originally Old Norse? No.

Used in the Viking Age? Late, Christianised.

Pre-christian evidence? No.

Typical for heathens? No.

Historically correct for christian Northmen of the 11th-12th centuries? Yes.

- Pagan Viking Age (8th-10th century): inappropriate
