The International Criminal Court is a special court that deals with issues of crimes that are serious enough to be considered a crime against all people. This means crimes like people killing other people in war or leaders who have harmed a lot of people, not just those in a single country. The idea is that no matter where the crime is committed, people should be held responsible for their actions and punished for doing bad things. The court is made up of judges from different countries who all agree to work together to find justice for people who may have been hurt by criminals. They also work together to make sure that people who committed these crimes don't just go unpunished and that they don't do the same bad things again.
