These days very few people think about or remember what took place during those four terrible years. We forget too that the seeds for World War II were germinated during World War I. Germany was humiliated and bankrupted by the terms of the Treaty of Versailles, and Adolf Hitler took advantage of German anger and frustration to take power.
Though we tend to remember those who died during World War I on November 11th, I think we should also try to understand why the war began in the first place. You will find some wonderful books for young people about World War I on the TTLG website on the World War I feature page. I hope you find something here that interests you.
