...like when you see German museums talking over and over about the "period of migration". First time I saw that it took me a while to understand what they were saying...

"Oh, that's what the Anglosphere calls //the barbarian invasions//".

(...or, I think every country has a statue of its native son who invented the television. Some are people I'd never heard of.)

The naming has nothing to do with Germany but is a common term describing migratory movements that where in part invasions into the Roman Empire, no all of those migrations into Roman territory where violent though. That invasion connotation seems to have carried over into present time. https://en.wikipedia.org/wiki/Migration_Period
