the anti-jewish sentiment in europe goes back to the early middle-ages, and only fell out of fashion (mostly, until recently) after the holocaust and the de-nazification programs in austria/germany.
same goes for anti-roma/sinti racism and anti-black racism; very old concepts, always convenient tragets for the far-right, since the sentiments are difficult to completely eradicate and easily spread by mass media.
for additional context:
