Pretty much in the title. I'm interested in learning more about the Aztecs. Religious beliefs, culture, hierarchy, etc. Can anyone reccommend any books?
There is always Michael Smith's famous book The Aztecs. If you want to get really in depth there is Sahagun's Florentine Codex written shortly after the Conquest.
I found this really useful for a beginner The Aztecs: Rise and Fall of an Empire
