No military action led to the start of WW1; the catalyst to WW1 was the assassination of Franz Ferdinand, the archduke of Austria-Hungary. His murder by Gavrilo Princip - a Serbian nationalist, caused Austria-Hungary to declare war on Serbia, which drew the other European countries into the war due to their existing treaties of mutual defense.
