Also the modern far-right in Germany has an undercurrent of monarchists, we've just lost the political language to label them as such - much like how we unironically refer to conservatives as "centrists" because referring to anyone but a nazi as "right-wing" is often implied to have certain undertones, although the conservative party that helped pass the Enabling Act was literally called the Christian Center Party.
And although the Nazis weren't exactly ideologically coherent - fascists generally aren't - the driving ideology in the modern German far-right (including within the AfD) is actually völkisch nationalism which the Nazis were at least making heavy use of in their propaganda.
I'd even argue remnants of völkisch nationalism even made it into the German constitution: it uses the term Volk and Volkszugehöriger (in Art. 116 Abs. 1 GG) without defining either of them. The definition of Volk instead had to be provided by a constitutional court ruling - German citizens plus Volkszugehörige - and that second term is defined in a seperate law (§ 6 BVFG) which uses a very narrow and arbitrary definition that's clearly a condensed bureaucratic remnant of a much broader ideological pre-existing definition (arguably the consequence of having to deal with a similar problem as laws trying to combat racism that want to avoid validating "race science" by pinning down exact definitions for each relevant category)[0].
Also in German popular culture the colloquial definition of "Deutsch" seems to be very much colored by völkisch ideas: someone who is "ethnically distinct" (e.g. skin color, eye shape) is generally regarded as a "migrant"/"foreigner" even if they are German citizens, speak fluent German, are culturally German and have multiple generations of direct ancestors who lived in Germany.
