So as the title says I'm not sure if this is the right sub to ask this question in but it seemed the most likely. I've always been kind of interested in World War II and the Nazis ideology versus the Americans and the rest of the world and want to learn more about their political system beyond the standard Nazis equal evil that I learned in school. But rather than just getting a quick overview of it I basically want to tear it apart and studied it down to its smallest pieces. Can you recommend any books? It can be old original material or new print. Obviously I'm looking for the least biased sources.
Fascism is notoriously (and somewhat surprisingly) difficult to define precisely as an ideology. Nazism also underwent a series of changes over time that makes it hard to pin down completely, as it was different things at different times, especially before it became tied to Hitler as it's personification, though even Mein Kampf underwent revisions over time.
Anatomy of Fascism by Robert Paxton gives a pretty good overview of the scholarship on the subject of fascism, which is a deep, broad, and contentious area of political and historical study with only pockets of consensus.
You may also use the term "Rise of Nazis" in a book search - there are at least a dozen or so books with that in the title, most of which cover the relevant areas of your question, though each from somewhat differing academic/historical perspectives and/or source material.
