Causes of WWI

World War I was an extremely deadly war. Many innocent people were killed. The improvement of machine guns, poison gas, and other deadly weapons of war contibuted to the massive killings. One of the most important questions we ask ourselves is that how did the war start? There are many answers.
One of the biggest causes of this world war, was nationalism. Nationalism was the love for one's country. Because of this love, it fueled the hatred that one ocountry had for another. Countries would make speeches or hang posters to show which side they supported. Countries who supported one another would do their best to support and defend their friends. Those who were enemies would do everything in their power to kill the other.
Another cause of the world war was militarism. It was how each country was able to keep their own military up to standards. This meant that they kept their military ready for war at all times. The european countries all had powerful armies. Each one had their own plan to dominate the other civil authorities. Before even going to war, armies would have a full scale battle plan drawn out.
Another cause of the world war was the assassination of king Ferdinand of Austria-Hungary. He was killed by someone from Surbia. Austria-Hungary realized they had a right to blame Surbia for the killing of their leader. Becaus of this they decided to declare war. This event leaded to the start of World War I. One of the most deadliest wars in the world. I have to admit its hard to believe.
