World war 1 essay

<p>Hey guys. I have to do an essay on Monday in HL history class for 40 minutes, which is stupid, but whatever. So, my teacher doesn't want us to have a thesis like "world war 1 was caused by nationalism, the alliance system, and militarism" but, I don't know how else to write it. I know she wants us to talk about the several disputes in the Balkans. However, I don't know how to word this to make it sound spectacular. I need three causes and I can go from there easily. Please help.</p>

<p>Talk abou the balken powderkeg?</p>
