Looks like what I'm looking for, thanks!

Another request -- I'm interested in a book that goes into depth about the causes of WWI. Not just the immediate causes (the assassination of Franz Ferdinand, the naval arms build-up between Germany and the UK, etc.), but also long-term issues like the enmity between France and Germany, the decline of the Ottoman Empire, the trouble in the Balkans, etc.

Also -- and this could be for a separate recommendation -- I'm interested in reading about the ideological motivations behind the war (but preferably something less simplistic or at least more multifaceted than the idea of WWI being a war about liberalism).

Thank you, added to my list!

Anyone have any reccomendations on books about the Parthian Empire?
