International Day of the Disappeared is observed on August 30, 2019. It is a day created to draw attention to the fate of individuals imprisoned at places and under poor conditions unknown to their relatives and/or legal representatives.
The impulse for the day came from the Latin American Federation of Associations for Relatives of Detained-Disappeared (Federación Latinoamericana de Asociaciones de Familiares de Detenidos-Desaparecidos, or FEDEFAM), a non-governmental organization founded in 1981 in Costa Rica as an association of local and regional groups actively working against secret imprisonment and forced disappearances in a number of Latin-American countries.
Work on secret imprisonment is an important part of the activities for a number of international bodies and organizations in the fields of human rights activism and humanitarian aid. But the definition of the Missing or the Disappeared goes far beyond the victims of enforced disappearance. It includes all those whose families have lost contact as the result of conflicts, natural disasters or other tragedies. (With material from: Wikipedia)
