WW1?

Which Historical event

WWI

For my question so far I have decided that I will investigate the accuracy of historical events in film, after some evaluation I realised doing one historical event will be better as I only have 5000 words maximum to write about it. Therefore I must choose between several different historical time periods/events and decide which one I want to investigate the accuracy of.

World war one (1914 - 1918) is a period in the 20th century which I find incredibly interesting, from the assassination of the Archduke Ferdinand to the armistice signed by Germany on 11th November and all that occurred in between - as the first world war there were so many advancements, so many new things learnt and so many untold stories. 

As a topic it is rich in detail and is amazing to hear about, even to this day and so to conduct and investigation into it would be very interesting. Having said that thought WWI is quite a broad topic (4 years) and so condensing all the information may be hard therefore although I would thoroughly enjoy researching about WWI I may look at other historical events before choosing which one to include as part of my question,
