Well close to the rise of the Nazis so I suppose it depends how OP defines build up.
While fascism might have stirred in Germany well back in the 20s, there isn't really any reference to it in the film so not really relevant to what the OP is looking for.

You get a sense of the suppression of everyday families within this film which is good.
