“Princip was one of three men sent by Dragutin Dimitrijevic, the chief of the Intelligence Department in the Serbian Army and head of the Black Hand, to assassinate Archduke Franz Ferdinand, the heir to the Austro-Hungarian throne, during his visit to Sarajevo on 28 June 1914.”
From a leading WW1 site. I’ve just read a couple of books by top historians and this is well-established fact, not propaganda.
The activities of the “Black Hand” in Serbia, of which Dragutin Dimitrijevic was a leader, were not officially sanctioned by Serbia. They would be considered “rogue elements”.
Be careful about taking “well accepted facts” by “top historians” as “truth”. There are many “well accepted facts” that are not “facts” at all, but rather manufactured lies and/or deceptions intended to present history a certain way to suit agendas.
