At 11am on 11 November 1918, the First World War came to an end. Today, 108 years later my students and I began an article about World War I. Although many people know quite a bit about WW II, not many know about WW I anymore.
In order to be a world war, fighting has to take place on every continent at the same time. The two world wars took place 21 years apart. When you look back at it, the first world war was a direct catalyst for the second world war. Many historians consider the 21 years between the two world wars as an armstice rather than true peace.
