Since becoming a teacher, I’ve been disturbed by the number of people who claim that the First World War was caused by a sandwich.  Having read a huge amount of sources about the assassination of Archduke Franz Ferdinand, I’ve put together this video that presents a detailed look at the claim that Gavrilo Princip was able to assassinate Archduke Franz Ferdinand and cause the First World War because he went to buy a sandwich from Schiller’s Delicatessen.

My video was inspired by Mike Dash’s excellent article at http://blogs.smithsonianmag.com/history/2011/09/gavrilo-princips-sandwich/ – it’s well worth ten minutes of your time to read it.
