European Civil War

Okay kiddo, so a long time ago, there was a big war called World War II. It happened because some countries in Europe wanted to take over other countries and do bad things to people because of their religion or race. Many people died and it was very sad.

After the war was over, the countries in Europe wanted to be friends and work together to prevent another war from happening. They created something called the European Union which helped them trade things and work on things together.

However, sometimes people in different countries still didn't agree on things and got upset with each other. This led to a lot of arguments and disagreements between different countries. Some people thought that this could lead to another war, like a civil war within Europe.

But don't worry, it's not happening right now and the countries are working hard to make sure they stay friends and don't fight with each other.
