The assassination on 28 June 1914 of Archduke Franz Ferdinand of Austria, the heir to the throne of Austria-Hungary, was the proximate trigger of the war. Long-term causes, such as imperialistic foreign policies of the great powers of Europe, such as the German Empire, the Austro-Hungarian Empire, the Ottoman Empire, the Russian Empire, the British Empire, France, and Italy, played a major role. Ferdinand's assassination by a Yugoslav nationalist resulted in a Habsburg ultimatum against the Kingdom of Serbia.[9][10]
Marge Runkle on 15 Jul 10Debatepedia is "the Wikipedia of pros and cons". Its mission is to "clarify public debates and improve decision-making globally". Debatepedia is a project of the International Debate Education Association (IDEA), a 501c3 non-profit. It utilizes the same wiki technology powering Wikipedia to engage you and other citizen-editors in clarifying public debates by centralizing them into a single pro/con encyclopedia. This helps you, other citizens, and leaders better weigh ALL the pros and cons, develop positions, and make more informed decisions, votes, etc... And this significantly improves democracy and people's lives.
