1 11.1 World War I Begins How did war break out in Europe while the U.S. tried to remain neutral?

2 What Conditions Led to War?
Four main factors led to the outbreak of World War I (1) Nationalism, or the belief that the interests of a single country were more important than cooperation among countries, which led to competition (2) Imperialism, where countries tried to increase power and influence around the world, which led to conflicts

3 Continued (3) Militarism, which was the building up of armies, navies, and other armed forces, and using them as negotiating tools with other countries (4) The Alliance System, where countries in Europe made treaties promising to defend each other Two main groups: Allies: France, Great Britain, and Russia Central Powers: Germany, Austria-Hungary, and the Ottoman Empire

4 Beginnings of the War In 1914, Archduke Franz Ferdinand was assassinated He had been the heir to the throne of Austria-Hungary His killer was a Serb who wanted to unite all Serbs (including those in Austria-Hungary) under one government The alliance system pulled one nation after another into the conflict; Germany and Austria-Hungary were facing France, GB, and Russia
