World War 1 started in 1914. This war was the first war to be global. Many nations and powers were involved in this war. The cause of this war was many things, such as the conflicts and hostility between the great European powers. Others were Militarism, alliances, imperialism, and nationalism. A more immediate origin of the war was because of the decisions made by the statesmen and generals during the July Crisis of 1914. The July Crisis was the assassination of Archduke Franz Ferdinand and his wife Sophie by Gavrilo Princip.
The war came after a series of diplomatic clashes between the Great Powers (Italy, France, Germany, Britain, Austria-Hungary and Russia). The war was between the Allies and the Central Powers. The Allied forces had 5,525,000 dead, 12,831,500 wounded, and 4,121,000 missing. The total was 22,477,500 Killed in Action, Wounded in Action or Missing in Action. The Central Powers had 4,386,000 dead 8,388,000 wounded, 3,629,000 missing. The total was 16,403,000 Killed in Action, Wounded in Action or Missing in Action.

I also got information from my Grandmother.
Both of these sources gave me the information I wanted but the website was hard to understand and some information seemed to contradict. When this happened I asked my Grandmother and she helped clear up my confusion. I give the website a 4/5 and my grandmother a 5/5.
I think this event is important because it was a huge changing point for the entire world. The world is a lot different now then it was then.
