If World War One had of been a bar fight.........

I was having a conversation with a friend yesterday about remembrance day and remembrance Sunday and World War 1 in particular. It turns out he didn't actually know anything about it past the fact that we beat Germany, in his words, 'sometime before World War 1.
It occured to me that a lot young people may not know the causes behind World War 1 and the details of the war so I've put this helpful guide together that should clear things up for them.
