Which Historical event?

EPQ

Which historical event?

After narrowing down the perimeters of my question the next thing to decide is what historical event/s to research and investigate for my question. There are many historical events I'm interested in so will evaluate each one individually and then choose which ones I want for my question, the different events so far are:

- WWI
- WWII
- Titanic
- Holocaust

However after doing some initial background research I have realised it will be better to pick just one, although it limits my research materials as I only have one event to look at it means my essay can be more focused and better structured. Therefore my decision when picking an event needs to be more precise as I can only pick one event, rather than 2 or 3 as originally thought.
