[On 28 June 1914,
Gavrilo Princip, a Bosnian Serb Yugoslav nationalist, assassinated
the Austro-Hungarian heir Archduke Franz Ferdinand in Sarajevo, leading to the July Crisis.
In response, on 23 July Austria-Hungary issued an ultimatum to Serbia.
Serbia's reply failed to satisfy the Austrians, and the two moved to a war footing. ]
Its sad that some Big Large displays
of WW1 Soldiers on a Wall in the UK
were Vandalized by young kids
who may think it was the Germans that started WW1
but it was a Bosnian Serb,
