Cause and effect WWII activity

Come up with a way to show the cause and effect system/chain of events/sequence that led to World War II, and then show it!

There is not one, lone event, in one singular location that leads to this conflagration; rather, there are several events and places that come together, so you will need to have a couple of starting points, and several in a series of events to adequately complete this task.

You need to show (Not tell! There is a difference here, right?) the cause and then somehow explain how it led to the beginning of World War II.

You may start your sequence at any point in World History and from any location on the globe.

You may not use printed words in this.  No headlines, or images of newspapers, either.

You may use any app you like, you may use images from any source to get your point across, and you may record your voice or let the images speak for themselves.

You must work alone, and you may use the textbook.

You must be historically accurate.

You will have 20 minutes to think and prepare, and then I will come around to see what you have created.
