The Netflix documentary The Long Road to War establishes that Germany wanted to start a war while avoiding being seen as the aggressor, while Austria-Hungary actively strived towards war with Serbia. In regards to my question, it is mentioned that security in Sarajevo was very light, especially considering recent attempts at Austrian governors' lives and in comparison to when Franz Joseph visited the city, and considering warnings from the Serbian government about potential unrest. To me, this seems to insinuate that the Austrian-Hungarians deliberately got Franz Ferdinand killed by willingly putting him in danger to advance their goals for war with Serbia, in this way serving Germany's policy as well. Some might even go farther and speculate that Austria-Hungary plotted towards the slaying.
Is there a historical consensus on this? Thank you in advance!
Yes and no as they couldn`t have foreseen an assassination attempt but at the same time they needed a casus belli. Jovan Jovanovic the Serbian diplomat in Vienna said there`re is a potential unrest in the making as the Serbian government found out weapons have been smuggled into Bosnia most certainly supported by Apis (Black Hand). So they knew and didn`t care. It is worth mentioning only 36 policemen secured the entourage of Franz Ferdinand.
In the time before the AH empire mobilized the army 3 times without actually attacking as the Serbian government always responded affirmatively on their ultimatums and they couldn`t afford financially to mobilize again without actually attacking.
