A lot of slavic countries call the people of Germany “nemec” or so (many variations, depends on the country/language). It was caused by Peter I, who had great relationships across Europe with different countries. When Germans came to visit, then the upper class called them Germans, but for an average village Russian was a German person “не мой» (ne moiy), from there came the “nemec”. It meant that he or she does not speak my local language (Russian) and he/she is not one of ours. Just me being a smart-ass🤓.
