Each of the 16 Bundesländer has a different curriculum (google "Lehrplan" for examples.).

I'm German. I could write multiple pages about it and still not cover it in its entirety. Your question also implies differences in how both world wars were viewed as opposed for say in the USA, GB or other countries.

That's interesting, because I on the other hand don't know much about how it is teached in other countries and would have to speculate. (If you want that, I could go into how from my perspective Americans often equate Wehrmacht Soldiers for Nazis and how this view is very different in Germany)

If you wish, go ahead and ask me any questions, but please be as precise as you can.
