Actually, the title is somewhat misleading, as part 1 of Patrick Crozier’s article concentrates on the (rather Anglo-centric) events of 1915:

But at the time, the British in particular, were short of everything. This would come to a head soon afterwards when Repington, again, claimed that the Battle of Neuve Chapelle could have gone much better had the British had enough shells. This would lead almost immediately to the creation of the Ministry of Munitions under Lloyd George.

By this time food prices were beginning to rise. Some foods were already up by 50%. Given that a large proportion of the average person’s income went on food this was inevitably causing hardship. Worse still, this rise took place before the Germans declared the waters around the UK a warzone. I must confess I don’t entirely understand the ins and outs of this but essentially this means that submarines could sink shipping without warning. The upshot was that rationing would be introduced later in the war.

Government control also came to pubs with restricted opening hours. It would even become illegal to buy a round.

So far the Royal Navy had not had a good war. It had let the German battle cruiser Goeben slip through its fingers in the Mediterranean and into Constantinople where it became part of the Ottoman navy which attacked Russia. An entire squadron was destroyed off the coast of Chile and even the victories were hollow. At the Battle of Dogger Bank the chance to destroy a squadron of German battle cruisers was lost due to a signalling error.

In Britain we tend to think of the First World War as being worse than the Second. This is because, almost uniquely amongst the participants, British losses in the First World War were worse. It is also worth bearing in mind that Britain’s losses in the First World War were much lower than everyone else’s. France lost a million and a half, Germany 2 million. Russia’s losses are anyone’s guess. For all the talk of tragedy and futility, the truth is that Britain got off lightly.

For many libertarians the First World War is particularly tragic. They tend to think (not entirely correctly) of the period before it as a libertarian golden age. While there was plenty of state violence to go around, there were much lower taxes, far fewer planning regulations, few nationalised industries, truly private railways and individuals were allowed to own firearms. If you were in the mood for smoking some opium you needed only to wander down to the nearest chemist.

In part 2, we actually get to some of the proximate causes that triggered the fighting:

So, what caused this catastrophe? If any of you are unfamiliar with the story it might be an idea to get out your smart phones out and pull up a map of Europe in 1914. When you do so you will notice that although western Europe is much the same as it is today, central Europe is completely different. There are far fewer borders and a country called Austria-Hungary occupies a large part of it.

As most of you will know on 28 June 1914, Archduke Franz Ferdinand, heir presumptive to the Austrian throne was assassinated in Sarajevo the capital of Bosnia which he was visiting while inspecting army manoeuvres. Bosnia at the time was a recently-acquired part of the Austrian Empire having been formally incorporated in 1908. Although the Austrians didn’t know this at the time – though they certainly suspected it – Gavrilo Princip, the assassin, and his accomplices had been armed and trained by Serbia’s rogue intelligence service. I say “rogue” because the official Serbian government seems to have had little control over the service run by one Colonel Apis. Apis, as it happens, was executed by the Serbian government in exile in Greece in 1917 and there’s a definite suspicion that old scores were being settled.

Oddly enough, the Austrians weren’t that bothered by the assassination of Franz Ferdinand the man. Apart from his family no one seems to have liked him much. His funeral was distinctly low key although there was a rather touching display by about a 100 nobles who broke ranks to follow the coffin on its way to the station. More importantly, Franz Ferdinand was one of the few doves in a sea of hawks. Most of the Austrian hierarchy wanted war with Serbia. Franz Conrad von Hötzendorf, the Chief of Staff had advocated war with Serbia over 20 times. Franz Ferdinand did not want war with Serbia. He felt that Slav nationalism was something that had to be accepted and the only way of doing this was to give Slavs a similar status to that Hungary had obtained in 1867. So his death changed the balance of power in Vienna. Much as the hierarchy were not bothered by the assassination of Franz Ferdinand the man, they were bothered by the assassination of Franz Ferdinand the symbol – the symbol of Austria’s monarchy and Empire, that is. The Serbs wanted to unite all the South Slavs: that is Slovenes, Croatians, Bosnians, Montenegrins and Macedonians in one state. However, most of these peoples lived in Austria. Now, if the South Slavs left there was no reason to think that the Czechs, Poles, Ruthenes or Romanians who were also part of the Austrian Empire would want to stay. Therefore, it was clear that Serbia’s ambitions posed an existential threat to Austria (correctly as it turned out). The solution? crush Serbia. And now the Austrians had a pretext.

For a longer look at the causes of WW1, I modestly point you to my (long) series of posts from last year on the subject.

Update: About an hour after this post went up, Patrick posted the third part of his series at Samizdata.
