A more systemic perspective explains that international humanitarian law represents a function of international human rights law; it includes general norms that apply to everyone at all time as well as specialized norms which apply to certain situations such as armed conflict between both state and military occupation (i.e. IHL) or to certain groups of people including refugees (e.g. the 1951 Refugee Convention), children (the Convention on the Rights of the Child), and prisoners of war (the 1949 Third Geneva Convention).
