The effect of the Great War was huge, on the countries involved. The worst effect countries were Germany, France and Great Britain as Germany had some 2 million men killed. But this is nothing to France's losses, France alone lost about 3 million troops, and about 5 million wounded, they lost about 75% of there whole military force. Also a lot of French towns were destroyed, and hundreds of acres of farmland were destroyed, by the Germans. This crippled the French economy for a while. Great Britain also, received heavy casualties from the Great War, but they were not as badly affected as Germany and France were.
But it wasn't until after the war that Germany felt the full effect of the war, in June 1919 the allied countries met in Versailles in France to decide the peace treaty, and how to punish Germany. They decided to strip Germany of its colonies (Lorraine, South Denmark and Bavaria.) Also Germany had to pay a whopping fine of 6,600,000,000 pounds, to pay for all the damage caused. To make matters worse, France took over most of Germany's western Factories; further crippling Germany's economy, making it difficult for Germany to pay the money. Most of the German public were forced to live in shelters and eat in soup kitchens, as there country went poor, so did they. Germany had really hit rock bottom, as its economy collapsed, people found it hard to pay for groceries, as the Deutschmarks value plummeted to 2 million deutschmarks per American dollar, loads of bread became millions of deutschmarks, and people could not afford it. So after the war Germany was the worst affected country out of them all.
Also in Eastern Europe, the other European power, the Austro-Hungarian Empire was broken apart, into smaller countries, Czechoslovakia, Slovakia and Poland. So there was no longer to big Empires of Europe, they were replaced with smaller less powerful and less threatening smaller countries.
