Causes of WWI

During the late 1800s, tensions began to rise between countries in Europe. Many countries began to stock up on weapons and military forces. Nationalism caused angry feelings between countries, and imperialism caused rivalry between countries. Alliances such as the Three Emperors Lead and Triple alliance where made in case of war. Many armies and navies where expanded because of militarism. Because of conflict, Serbia threatened Austria, and Russia threatened that they would support Austria.

Because of alliances made, Europe was split into two sides that where angry and in compition with each other to be the best. Each country beleived it was better than the other. All tension was let loose when a Serbia assassinated Arch Duke Franz Ferdinand. War broke out between the two countries, and because of previous alliances made with countries, other countries became involved in the war. Later on, because of American ships being destroyed by war, they too entered and helped the Triple Alliance win the war.
