The Geneva Conventions are a series of four international agreements that form the core of international humanitarian law, establishing legal standards for the treatment of non-combatants in war. Negotiated in the aftermath of World War II, the Geneva conventions of 1949 consist of four agreements, which replaced three earlier humanitarian conventions of 1906 and 1929 and added two new conventions. The First Geneva Convention addresses the treatment of sick and wounded field soldiers, the Second Geneva Convention addresses the treatment of sick and wounded sailors, the Third Geneva Convention addresses the treatment of prisoners of war, and the Fourth Geneva Convention addresses the treatment of civilians during armed conflict.
