How did each of the four causes contribute to ultimate war?
Nationalism caused intense competition among nations, with each seeking to overpower the other. By the turn of the 20th century, a fierce rivalry had developed among Europe’s Great Powers. Another force was imperialism. The nations of Europe were competing fiercely for colonies in Africa and Asia. The quest for colonies sometimes pushed European nations to the brink of war. As European countries continued to compete for overseas empires, their sense of rivalry and mistrust of one another deepened. Another cause was militarism. The nations of Europe believed that to be truly great, they needed to have a powerful military. By 1914, all the Great Powers except Britain had large standing armies. In addition, military experts stressed the importance of being able to quickly mobilize, or organize and move troops in case of a war. Finally, was all the alliances formed. Growing rivalries and mutual mistrust had led to the creation of several military alliances among the Great Powers. This alliance system had been designed to keep peace in Europe. But it would instead help push the continent into war. By 1907, two rival camps existed in Europe. On one side was the Tripe Alliance, and the other was the Triple Entente. A dispute between two rival powers could draw all the nations of Europe into war.
