Imagine that you are playing with your friends and you made rules for the game. These rules are there to make sure that everyone plays fairly and nobody gets hurt. They also help to avoid any misunderstandings and fights during the game.
The Fourth Geneva Convention is like a set of rules that countries agreed to follow during wars. It's named after a city called Geneva in Switzerland where many countries got together and made these rules.
One of the most important things about the Fourth Geneva Convention is that it protects people who are not fighting in the war. These people can be civilians or those who are hurt or sick. It also protects prisoners of war from being mistreated.
Just like how your game rules have punishments if people don't follow them, the Fourth Geneva Convention has punishments for countries that don't follow the rules. This helps to keep things fair and prevent anyone from getting hurt more than they already are.
Overall, the Fourth Geneva Convention is a set of rules that countries agreed to follow during wars to make sure that everyone is treated fairly and nobody gets hurt unnecessarily.
