International Holocaust Remembrance Day, is an international memorial day on 27 January commemorating the tragedy of the Holocaust that occurred during the Second World War. It commemorates the genocide that resulted in the death of an estimated 6 million Jewish people, 5 million Slavs, 3 million ethnic Poles, 200,000 Romani people, 250,000 mentally and physically disabled people, and 9,000 homosexual men by the Nazi regime and its collaborators
The International Day in memory of the victims of the Holocaust is thus a day on which we must reassert our commitment to human rights. […]
We must also go beyond remembrance, and make sure that new generations know this history. We must apply the lessons of the Holocaust to today’s world. And we must do our utmost so that all peoples may enjoy the protection and rights for which the United Nations stands.
