What caused World War 1?


assistant
There is no definite answer, however there are several speculations about what caused World War 1. An answer approved by many historians is the assassination of Archduke Franz Ferdinand by the Black Hand, a Serbian nationalist organization. This assassination led to Austria-Hungary declaring war against Serbia. In response to this declaration, many countries joined forces under the guise of 'alliance'.
