World War I

World War I, or The Great War, was a global war in which the "educated, sophisticated, and fancy" Europeans started a mortal armed conflict which also included clashes in other parts of the world, which lasted from 1914-1918. It was the sixth most deadly conflict in the history of mankind and later paved the way for a number of geopolitical changes, such as revolutions and new borders in many of the nations involved.

The immediate cause of WW I was Serbia. It pitted the Central Powers of German Empire and Austria-Hungary and their allies against United Kingdom and France, and their allies and adoptive children. It resulted in the signing of the Treaties of Versailles and Trianon, and the creation of a League of Nations, to ensure such a war would never happen again. However, despite such attempts, and even more destructive World War followed a mere 20 years later.
