How is assassination a cause of World War 1?

Answer 1

At the time of the assassination of Archduke Ferdinand, Germany and Austria-Hungary were allies. When the Black Hand killed Ferdinand, Germany felt it was their place to step in and bring the Serbians into line, thus aiding their ally. Russian and Turkey had substantial Serbian populations and so were sympathetic to their cause. Around this time, the western world was engaged in forging alliances and better arming themselves against some impending attack. Tensions were high, and Germany had been engaged in activities of a volatile nature, like undermining French authority in Morocco. The assassination itself drove Germany and Austria-Hungary to attack the Balkans, and from there, other associated parties joined the war. I don't remember very well why exactly Germany attacked France, but it can be found in any history textbook or database.

Answer 2

If I am right in thinking that the topic is the assassination of Franz Ferdinand in Sarajevo then this led to WW1 for the following reasons: Franz Ferdinand was heir to the Austro-Hungarian throne. He was assassinated in Bosnia by Gavril Princip, a Serbian member of the Black Hand. The Black Hand was supposed to have been funded by the Serbian government (or so Austia-Hungary said) and so they declared war on Serbia. Serbia was backed by Russia, so Germany joined Austria-Hungary and so the whole allied system came in to play. War began.
I have just been learning about WW1 so I might be wrong. The assassination of Franz Ferdinand (the heir to the throne) by a gang of rebels from Serbia, started a war between them, Austria-Hungary were allies with Britain, France and Russia, and they therefore went to war, and Austria-Hungary were allies with Germany. I am not sure about America and the other Nations.
