World War 1, also known as WW1, was a big and scary war that happened a long time ago. Imagine there were two groups of friends, and they started arguing about who was the best. These groups were called countries, like in a game. The countries were mad at each other, just like when you and your friends have a fight over a toy. They didn't want to share things and got very upset.

People in these countries started fighting with each other because they wanted more land, toys, and power. They used big machines and weapons called tanks and guns, which made a lot of noise and hurt many people. It was like a huge game of tag, but instead of playing for fun, they were fighting to win.

Many countries from all around the world joined the fight, and it became a very long and sad war. The fighting lasted for many years, and many people got hurt or had to leave their homes. Just like when you get a scrape on your knee, but much bigger and more serious.

After a long time, the countries decided they didn't want to fight anymore. They stopped playing the game because they were tired and wanted to be friends again. They signed a paper called a treaty to promise to be kind to each other and not fight anymore. That's how World War 1 finally ended.

Even though WW1 was a very scary and sad time, we can learn from it that fighting is not the best way to solve problems. It's important to talk and listen to each other so we can all live in peace and harmony.
