The concept of humanity has been much discussed with respect to humanitarian work and international humanitarian law. There is today an idea of a single humanity, with each member equally valued beyond superficial differences in belief, nationality, ethnicity etc., and a global legal framework exists to prevent needless human suffering, including in war.
Dehumanization arises linguistically as the negation of a common, positive and mutually supportive humanity, though there is no single definition, and it certainly predates its opposite. Research indicates that dehumanization increases the risk of conflict/violence, increases the risk of abuses therein, and makes it harder to resolve conflict.
This paper gives an overview of how humanity is currently defined and used, notably by the International Committee of the Red Cross (ICRC) as one Fundamental Principle of the International Red Cross and Red Crescent Movement, and what dehumanization means especially in relation to conflict and violence. The paper then explores why and how dehumanization happens and the real-world harm that can result when it is espoused or tacitly condoned by those in positions of power. Finally, the paper examines how global legal frameworks and the principle of humanity, bolstered by impartiality, independence and neutrality, in particular as enacted by the ICRC, work to curb and push back against some of the worst harms that dehumanization can cause.
The paper touches on the missing and their families as people whose humanity may be called into question in certain ways.
