Question

un eveniment care a zguduit lumea în engleză ​

Answer 1

World War 1 started in 1914 and a lot of countries fought in it like Romania, the USA, Russia, France, Germany and a lot more, I guess that's why it's called "World War" 1. Millions of soliders were killed, empires fell and new weapons were invented. It's one of the most important events that you learn about in history class, too.
