The Geneva Conventions, born from the ashes of World War II, form the backbone of international humanitarian law. These four treaties, along with their Additional Protocols, set rules for armed conflicts, protecting wounded soldiers, prisoners of war, and civilians. International criminal law builds on this foundation, defining and punishing crimes like genocide and war crimes. The International Criminal Court and other tribunals enforce these laws, aiming to end impunity for the worst atrocities and provide justice for victims.
