<h3>What were the long term causes of WW1 for austria-hungary?</h3>

I understand the background information but I am having trouble choosing out of the long term causes of the war, which ones relate to austria-hungary and how? Thanks so much.
Out of these causes and why:
militarism
arms race
nationalism
imperialism
assassination of the archduke
crisis


<strong>Austria best answer:</strong>
<p><i>Answer by Auseein</i><br/>militarism and arm race are similar so we can group it as one
i think it is imperialism becuz the serbians and bosnians were desperate enough to kill the archduke
the austrian hungary promise freedom in the balkans after the ottoman got driven out after the attempt seige of vienna but that never happened</p>
