It is generally accepted that the First World War was triggered by the assassination of Archduke Franz Ferdinand by the Bosnian Serb Gavrilo Princip. In recent years, however, an extra twist has been added: that the only reason Princip was in a position to fire at the Archduke was because he happened to be eating lunch when the Archduke’s car drove past. Millions of lives were lost during the war that followed. The Russian Revolution, the rise of Hitler and Nazism, the Second World War, and even the atomic bomb can arguably be attributed to the First World War, and thus, to the assassination of Archduke Franz Ferdinand. It’s sobering to think that all of those terrible things might never have happened if Princip hadn’t felt a little hungry and stopped off at Schiller’s delicatessen for a sandwich.
The sandwich theory, however, is deeply flawed. The Smithsonian blog published an excellent debunking of it back in 2011. It appears that the original source of the sandwich was a novel by a Brazilian TV host. The post is very interesting, and well worth a read.
