On June 28, 1914, Gavril Princip had participated in a failed attempt to assassinate Archduke Franz Ferdinand in Sarajevo. A co-conspirator had thrown a bomb at the Archduke’s motorcade but failed to hit his target. The motorcade got away from the planned route. However, not long thereafter, the Archduke’s driver took a wrong turn and, as he was backing up, the car stalled. As it happened, the car stalled in front of where Princip was standing. Taking his chance, Princip pulled out his pistol and shot the Archduke and his wife.
Princip was part of a Serbian separatist group that wanted parts of the Austro-Hungarian empire to split off and become part of a new Yugoslavia. The archduke was the heir apparent to the throne of the empire, so the Austro-Hungarian Empire was enraged and issued an ultimatum to Serbia – with a number of demands that Serbia simply couldn’t be expected to accept. After partially rejecting the ultimatum, Austria-Hungary declared war on Serbia. Serbia turned to Russia which regarded itself as “protector of the Slavs.” Austria-Hungary turned to Germany with which it had an alliance against Russia. Russia, in turn, had an alliance with France against Germany.
Germany’s plans for war with Russia (Schlieffen Plan) was premised on the notion that it would have to fight France in any conflict with Russia. Being situated between Russia and France, and believing it would take Russia some time to mobilize, the war plan for such a conflict required Germany to move swiftly into France, neutralize the forces there, and then swing back east to deal with Russia. The longer it entertained diplomatic solutions, the less likely the plan was to work. Additionally, the German plan took it through neutral Belgium to get to France more quickly. England was allied with Belgium against violations of its neutrality and was drawn into the war when Germany invaded.
There are a lot more details and nuances involved in the beginnings of World War I, but that’s the thumbnail sketch. The details get hopelessly complicated pretty quickly. But, at that point, Europe was like a forest full of dry dead wood and undergrowth. The relatively small spark of Princip’s assassination of Franz Ferdinand was all it took to set the whole thing off. The Great War was really a bridge into modern times. The early parts of the war feature guys on horses with plumed uniforms and whatnot facing off against industrial weaponry. The conflagration would turn into an absolute meat grinder, particularly after it settled into the trench warfare for which it became famous. It was a war of attrition on a scale not previously seen. And, for the most part, it seems that the combatants were fighting out of a combination of pride and accident.
It tends to be a forgotten war – overshadowed locally by the “good” wars like World War II, the Civil War, and the Revolutionary War, where the United States can be discussed in heroic terms and the narrative of the war and what it accomplished can be stated more simply. But, I think we ignore the lessons of World War I at our peril: that pride and lack of foresight can cause enormous losses; that there is nothing inherently noble about war; that individual bravery can be meaningless.
I suspect I’ll have more to say about the Great War in the near future. Among other things, I was a history major in undergrad and Great Britain’s involvement in World War I was the subject of my senior seminar. I don’t pretend to be any kind of an expert, but it’s an area of interest for me.
