We'll start with the facts and work back: it may make it all the easier to understand how World War One actually happened. The events of July and early August 1914 are a classic case of "one thing led to another" - otherwise known as the treaty alliance system.
The explosive that was World War One had been long in the stockpiling; the spark was the assassination of Archduke Franz Ferdinand, heir to the Austro-Hungarian throne, in Sarajevo on 28 June 1914.
Ferdinand's death at the hands of the Black Hand, a Serbian nationalist secret society, set in train a mindlessly mechanical series of events that culminated in the world's first global war.
Austria-Hungary's Reaction
Austria-Hungary's reaction to the death of their heir (who was in any case not greatly beloved by the Emperor, Franz Josef, or his government) was three weeks in coming. Arguing that the Serbian government was implicated in the machinations of the Black Hand (whether she was or not remains unclear, but it appears unlikely), the Austro-Hungarians opted to take the opportunity to stamp its authority upon the Serbians, crushing the nationalist movement there and cementing Austria-Hungary's influence in the Balkans.
It did so by issuing an ultimatum to Serbia which, in the extent of its demand that the assassins be brought to justice effectively nullified Serbia's sovereignty. Sir Edward Grey, the British Foreign Secretary, was moved to comment that he had "never before seen one State address to another independent State a document of so formidable a character."
Austria-Hungary's expectation was that Serbia would reject the remarkably severe terms of the ultimatum, thereby giving her a pretext for launching a limited war against Serbia.
However, Serbia had long had Slavic ties with Russia, an altogether different proposition for Austria-Hungary. Whilst not really expecting that Russia would be drawn into the dispute to any great extent other than through words of diplomatic protest, the Austro-Hungarian government sought assurances from her ally, Germany, that she would come to her aid should the unthinkable happen and Russia declared war on Austria-Hungary.
Germany readily agreed, even encouraged Austria-Hungary's warlike stance. Quite why we'll come back to later.
One Thing Led to Another
So then, we have the following remarkable sequence of events that led inexorably to the 'Great War' - a name that had been touted even before the coming of the conflict.
With Germany's invasion of Belgium on 4 August, and the Belgian King's appeal to Britain for assistance, Britain committed herself to Belgium's defence later that day. Like France, she was by extension also at war with Austria-Hungary.
In short, Italy was committed to defend Germany and Austria-Hungary only in the event of a 'defensive' war; arguing that their actions were 'offensive' she declared instead a policy of neutrality. The following year, in May 1915, she finally joined the conflict by siding with the Allies against her two former allies.

The main cause of WW1 was the assassination of Archduke Franz Ferdinand.
main ones: Germany, austria, (italy)
the main reason for the war is that issues of ww1 had not been settled to the satisfaction in Germany in particularly. Germany as we know was to blamed for, for the outbreak of ww1 ,yet she felt that she was unjustly punished and refuse to co-operate with the new rules. Once more the agressor on the European Continent.

The proximate cause of WW1 is the assassination of Archduke Franz Ferdinand. There are four main causes of the starting of WW1. They were Militarism, Alliances, Imperialism, and Nationalism. In militarism countries aggressively built their nations armed forces. For the alliances, each nation in the allies protected the others. Imperialism is when the countries competed to control other colonies, and nationalism is the devotion to your nation. These are the four main causes of WW1.
