Does anybody now anything about world war i plus i need notes?

Europe was a Continent in crisis during that time. Many people found war as something that should be glorified. However, the straw that broke the camel's back was, when Archduke Franz Ferdinand (of the Austro-Hungarian Empire) was visiting Serbia, Sarajevo to be exact, and was shot and murdered by Gavrilo Princip, part of the Black Hand. 
This was than followed up by The A-H Empire giving Serbia an ultimatum, however Serbia did not comply, so as 1914 Europe would've done, they threatened to attack Serbia, however Russia, who was on Serbia's side threatened to attack A-H empire if they dared to attack, which cause Germany to write a 'Blank cheque' for A-H to use against Russia. 
On the other side of Europe Germany was attacking the north of France, which brought England into the War followed by Australia than USA.
