Hey there!
So, I'm wondering if the 1910s had any other possible event or action that might have triggered a global conflict, instead of Princip and the Austro-Hungarian heir? I'm looking for anything that might have happened between 1909-1915, nothing later than that. Any ideas? I've tried to do some research on Sakhalin island and the Russo-Japanese conflict, but that doesn't seem plausible enough.
So, would any of you know? Could some other event have triggered the first World War?
