“Hitler’s rise to power was an amazing time in history, a perfect storm as it were. But he was still an Austrian.”
I seem to recall Hitler became an official German citizen about the time he became Chancellor. I might be wrong, but it seems I read this in “The Rise and Fall of the 3rd Reich”.
Yes, Hitler was Austrian but was made a citizen of Brunswick, Germany, by a local Nazi official in 1932. This made him a citizen of Germany.
