1 The MAIN causes of World War I MILITARISM – The growth of nationalism and imperialism led to increased military spending ALLIANCE SYSTEM – By 1907 Europe was divided into two armed alliances IMPERIALISM – Economic and political control over weaker nations NATIONALISM – a devotion to the interests and culture of one’s nation

2 Nationalism: led to rivalries and conflicts between nations. Several ethnic groups were ruled by a European power. Ethnic groups did not want to be dominated by others and wanted independence. Russia and Austria-Hungary disagreed over the treatment of Serbs in central Europe.

3 Imperialism: European nations built empires. Colonies supplied raw materials and provided markets for manufactured goods. As Germany industrialized, she competed with other nations and colonies made her more competitive. Militarism: Empires had to be defended and European nations increased military spending enormously in the late 19th and early 20th century. By 1890 the strongest nation militarily in Europe was Germany Germany had a strong army and built up a navy to rival England’s fleet. France, Italy, Japan and the United States joined in the naval buildup.

4 By 1907 there were two major defense alliances in Europe The Triple Entente, once the war started were known as the Allies, consisted of France, Britain, and Russia and later the United States The Triple Alliance, once the war started were known as the Central Powers, consisted of Germany, Austria-Hungary, and Italy were later joined by the Ottoman Empire.

12 No man's land: The Territory Between the Trenches The territory between the opposing front trenches was marked with huge craters caused by the shelling; nearly all vegetation was destroyed. Both sides filled this land with barbed wire to slow down any rapid advances by the enemy. The machine gun and the new long-range rifles made movement in this area almost impossible.
