WWI is an obscure history to most people. Even 100 years later there’s no real agreement on why it erupted.
If you like to read Barbara Tuchman’s “The Guns of August” is excellent. She was an amateur historian and a very good writer.
I still believe had Britain, and subsequently America, stayed out of the fray in WWI, the world would have been much better off.
Guns of August is excellent, as you say. Just came back to this thread, and had not copied a comment i made earlier about a dramatized history series “Fall of Eagles”— some 13 episodes-— covering Hapsburgs from 1848 through WWI, Bismarck and his influence on Franz Joseph (Prussia attacking Austria,and uniting a German state) as well as his removal by Kaiser Wilhelm (upon ascending the throne after his father’s death from throat cancer).
The segments on Russia cover rather well the machinations that created WWI (from their own foreign minister and the Austro Hungary diplomat Aerenthal, who annexed Bosnia, and the Serbs were plenty ticked about that.
It’s a great series- described by episode on wikipedia. Much to be learned about how our current demonrats are operating exactly like Bolshies did (all the hitlery obama “resistance” crap spewed,etc.)
