Hitler was from Upper-Austria. Before moving into politics and moving to Munich, as a wanna-be art student in Vienna he was poor and rejected from academia. My personal opinion from reading about him is that he did not really like the cultural thrivings of Vienna. So after annexation of Austria, he ordered to prepare plans to transfer his Upper-Austrian hometown of Linz into a "cultural capital". See: https://en.wikipedia.org/wiki/F%C3%BChrermuseum
