When World War I broke out in August 1914, both the Central Powers and the Allied Forces believed that it would be over by Christmas of that year.

One of the most important reasons that the First World War lasted so long was the failure of the Schlieffen Plan. The Schlieffen Plan was an operational plan used by the Germans to take over France and Belgium and carried out in August 1914.
