The Treaty of Versailles was what ended war with Germany, requiring them to pay for the damages of WW1, forcing them to disarm their military, and accept responsibility for causing the war. This map shows how the Treaty created nine new nations as well, now that the Central Powers had to surrender their colonies to the Allies.
The above political cartoon is about the Treaty of Versailles which ended World War I. The cartoon shows the Treaty of Versailles document rolled up and a man crawling out of it wearing a German helmet that says "Hitler's Party". The significance of this is that it shows that the Treaty directly created Hitler's fascist Nazi party which would plunge the World into another long and devastating war, World War II.
