Abstract
After the Second World War in 1945, the notion of ‘crime against humanity' emerged to condemn the killing of the Jews by the Nazis. In reaction to this shock, several countries stood in favour of conveying a new way of thinking about international relations, and tried to set up a new kind of intervention. This concept is commonly called humanitarian intervention, and is associated with the normative theory. If an intervention has been traditionally defined as a breach in the sovereignty a state which interferes in this state's internal affairs , the humanitarian intervention claims to reach a different goal. It aims at preventing any potential mass killing and genocide in the future, at helping people and at guaranteeing the respect of the Human Rights. However, there is actually no exact definition, as it remains a controversial theme. There are various types of humanitarian interventions, which can be classified such as the forcible ones, the non-forcible ones, the long-term ones or the short-terms ones.
