World War I
WWI
WWI is just that, one of the 2 wars that involved the whole world. Half of Europe, Russia, and the U.S. so not the whole world but about half of it. WWI was one of the most horrific wars in history. This war was full of new technology in weaponry, and new strategies to help win the war. Some new creations were, trench warfare, dogfights, and u-boats. A strategy that Germany had was to march through a neutral country to surprise the enemy. That didn't work out well though.That country declared war on Germany and helped the other side win.
The Treaty of Versailles
The Allies got dealt a huge blow when Russia dropped out of the war. This gave the central power an advantage because Germany could focus all of it's attention on the eastern front. The Allies powered through though and won the war by strength. They then signed a peace treaty except for a few countries who thought Germany should be punished and should have to pay for all the damage they caused.
