5. Alliances By 1914 all the major powers were linked by a system of alliances. The alliances made it more likely that a war would start. Once started, the alliances made it more likely to spread.

6. Imperialism All the great powers were competing for colonies / territory. The British feared Germany in Africa. The Austrians feared Serbia / Russia in the Balkans

7. Nationalism This was an age when all nations wanted to assert their power and independence. In Europe Slavs, aided by Serbia and Russia, wanted to be free of Austrian rule. Serbia’s national flag

8. Significant Individuals 1. Kaiser Wilhelm II Built up German army and navy Aggressive foreign policy Determined to make Germany a top nation. Distrusted by other powers “Germany must have its place in the sun” “The world belongs to the strong.”

10. Significant Individuals 3 Bethmann Hollweg German Prime Minister Gave very strong support to Austria during the July crisis while Kaiser was cruising on his yacht “The Austrian demands are moderate. Any interference by Britain, France and Russia would be followed by incalculable consequences”

11. The Crisis 1. 28 June 1914 Heir to Austrian throne Franz Ferdinand visits Sarajevo. Capital of Bosnia, recently grabbed by Austria. Hotbed of Slav nationalism Seal of the Black Hand group

Russia mobilises her troops to support Serbia Germany demands that Russia stands her armies down.

17. Why did it take so long for America to get involved in the war? America was isolationist. –“Why should I get involved in someone else’s problems?” The Monroe Doctrine (1823) sought to isolate “the American continents” from European influences and problems. In this cartoon, “The Great Wall” (1914), the Monroe Doctrine is shown as a protective shield for the United States.

18. Submarine Warfare The Germans warned Americans their merchant ships might be hit. Reaches a crisis point after Lusitania is torpedoed in 1915—128 Americans died. After sinking of British and French liners, Germans promised they would not sink unarmed ships without warning  SUSSEX PLEDGE

23. How was the war looking for the allies? Russia left the war after its communist revolution in 1917. Russia’s withdrawal allowed Germany to fight a one- front war with all its troops concentrated on France (remember this point when you study WWII!). Not Good... Calling for a Communist revolution, anti - Tsarist protesters gather outside the Winter Palace in Petrograd, Russia, February 1917.
