Kate TreanorMrs. MillerModern World History 12 December 2017The Main Cause of World War I World War 1 was strongly impacted by four major factors, including imperialism, militarism, the system of alliances, and nationalism. Specifically, imperialism was the most important factor and main cause to World War 1 because it created tension throughout Europe as well as outside it. Imperialism is driven by the want of materials, economic and political power, and for control of markets. In simpler words, imperialism can be explained as the want of power and control, causing a country to take it from less powerful nations.Throughout history imperialism has lead to fights between countries over territories that can in server cases result in war. In the events leading up to World War 1 disagreements about territories caused tension between nations. For example, European military powers expanded their empires by gaining new territories in places like Africa, the Caribbean, and Asia creating conflict between the territories. Europe is a very powerful country and had the power to take over nations, making others angry. Another example of how imperialism lead to World War 1 is the fact that Germany and Austria Hungary’s resources were running out and an easy solution for them was to expand their foreign colonies. Since Europe had such high power and a lot of control over foreign colonies, it made the competition of expanding territories hostile. Imperialism lead to many national rivalries leading up to World War 1. It created feud between nations that ultimately resulted in full fledged war. Lastly, Europe was discovering mass production benefits because of industrialization motivating, them to take control over less powerful countries to gain resources. Overall, imperialism created national rivalries making tension between nations. Out of the four main causes of World War 1 imperialism had the largest influence because of the chain reaction it caused. Specifically, imperialism lead to nationalism, militarism, and alliances. Firstly, alliances are when two or more nations have a agreement driven for mutual benefit. During World War 1 many alliances were created because of imperialist nations becoming extremely powerful, negatively affecting smaller nations. An example of an alliance that was formed during World War 1 is the triple alliance, including Italy, Germany, and Austria Hungary. Without imperialistic nations gaining power, alliances would not of been necessary, creating a lower chance of war. Militarism, the next cause of World War 1 is when a country glorifies their military. People who live in a militaristic country believe their military should be respected and praised. During World War 1 an example of a militaristic country was Germany. Germany believed having a strong military made them great, encouraging them to build up their military to showcase their power. Militaristic nations built up their navies as a demonstration of power and a use of defense. Without imperialism creating tension between nations militaristic countries would not need to go to war. Lastly, nationalism is the belief that the interests of a nation are of superior importance. A nation who is nationalistic believes they should have freedom of foreign dominance. Nationalistic nations have overconfidence and love for their country creating hatred for another. Nationalism created a feud between two nations, but not an entire reason to go to war, showcasing how imperialism gave nationalistic countries a reason to turn a fued into war. In conclusion, imperialism was the main cause of World War 1 because it caused tension between nations which then created a chain reaction including alliances, militarism, and nationalism.
