I was thinking about the german Versammlungsgesetz and requirements to stay identifiable while operating dangerous machinery in public ("driving"), but apparently I was completely wrong about their age (actually late 20th and late 2010s, I was assuming "possibly leftover from some reich"). Still, those two were not motivated at all by rejection of imported culture, but in terms of timing they might very well have been.

711 if we ignore the failed siege of Constantinople. But I don't think that's in any way related to what gp was talking about?
